Hilti C4/36-350 Charger Issue: Green LED Flashing Every 2s, Battery Not Charging

I ordered one, I put it in and it works L6599AD and what damage is the status of the charger, what is the green diode? Is there any physical damage to the resistor system? Sometimes it rains MIP2M2, it does not necessarily have to be this system as above

The diode lights up for exactly 0.5 seconds and goes out after inserting the batteries, the same. For now, I checked the L6599 and it has a return to ground on the power supply. One of the keys is also compact, but instead I want to insert STF15N80K5. The original is not available either. I'll check the parts today, but that's not a problem. Has anyone put L6599D there or others that I can have by Friday?
Physical damage is not visible.
Thanks for the help.

I put L6599D and everything is OK, it so happens that I also could not buy the AD version and from the "Aledrogo" auction I bought 3 pcs of the D version; when they came, I didn't even notice that the seller gave me one AD and 2 pieces of D



to sum up, both systems will work in this charger;

if the diode does not light up, you have damaged IC2, and when it flashes for a moment, something sticks around IC1; remove keys chip IC1; check if its outputs are sticky; check diodes and capacitors for short circuits; search until the LED lights up and there is 13V, i.e. described above / earlier ... and when the LED is on, you can proceed to the assembly of IC1.

I also could not buy the original insulated keys and how I dealt with it read above ... good luck

R24-30-33-38-39 dirençleri sağlamsa ZD11(15V) diyot değiştir deneme yapmak için L6599AD olmasına gerek yok.

Hello, I will stick to the topic of the famous charger.
It came to me as in the subject.
In short, no reaction to connecting the power supply, apparently when it stopped working, the protection in the switchgear broke. At the beginning of my adventure, I picked up the L6599AD from the PCB and removed the 12N50DM2 keys. The fuse on the power supply was blown, which I replaced. Now, when the 230V~ power supply is connected, there is no voltage on C3. I checked the branch that powers L2 and it seems to me that the problem is on ZD1 - ZD6 zeners.
I add a small fragment of the schematic ... for clarification.

ben iki aşamalı olarak arızaya bakıyorum.ilk kısım yeşil led aktif ama şarj başlamıyorsa L6599ad kısmını kontrol ediyorum genelde şarj akımını okuduğu şönt direnç hattı üzerindeki R31-ZD16-D9 elemanlarında çıkıyor.
ikinci olarak yeşil led aktif değil ise mip2m2 ile ilgili kısıma bakıyorum.Bu tarafta mip2m2 çalışabilmesi için R24-R30-R33 hattının sağlam olması gerekiyor ayrıca ZD11 kontrol ediyorum.

Mine looks a bit different.

şarj cihazlarını test ederken seri lamba kullanmanı tavsiye ederim bu sayede parçalar zarar görmeden denemeler yapabilirsin

jumper kontrol edebilirmisin bazen sigorta patladığında kopma oluyor.

Today, having a moment of time, I checked / replaced ZD16 D9 ZD9 ZD11 ZD14 ZD17, as a result, the LED lit up.
MIP2M2 heats up despite the lack of L6599AD and 12NM50ND, is it normal that it heats up?

It should not heat MIP2M2, do you have 13v on 4 pins? what voltages do you have on the outputs of transistor Q5? give me the voltage value on MIP2M2 pin 5 watch out there is high voltage!!!

Hello, sorry for the late reply.
4 pin mip2m2 = 13V
5 pin mip2m2 = 275V
================
Q5
B to ground = 0V
E to ground = 0V
C - analogy, i.e. 13V

so yes, MIP2M2 generates you on pin 4: 13v correctly, but on pin 5 you probably have too low voltage because I had 327v there (unless the measurement was wrong)

the voltages I had on IC2; working charger after repair, he gives again:

pin 1/3: 5.97v;
pin 2: 1.9v;
pin 4: 13.02v;
pin 5: 327v
pin 6: none
pin 7: ground
pin 8: 1v;

you definitely have a damaged circuit in the vicinity of Q5, because on E- you should have 13v on the base, I don't remember how much it should be, but for sure some voltage for the base of the new Q5 (I mark my transistor has been damaged) check the resistor R50 and R49; provide voltages on PC4 optriotrak if this circuit is checked and sure that there is no damage the problem lies before PC4 (VO615A) that is where you had a fault I shoot because on the original PC4 I did not draw a diagram because I did not need it for analysis and I will not help you in the analysis no problem... that's all from me

Hello.
Before D5, and after ZD12 it is 327V, while after D5 it is 267V. ZD14 and ZD15 I still have "old". I do not know the value to prophylactically replace, because on 2 MIP pins 0V. MIP 8 pin 0 R to ground (short circuit).

Before D5, and you write after ZD12 (probably a mistake here because ZD13) is 327V, while after D5 267V.

Are you sure because I had 327V on pin Ic2 5 to 327V then I jump on the T2 transformer maybe on pin no. 1 of this transformer is what you write, and tell me on this transformer what voltage you have on the D104 diode and probably the capacitor C111 or there is C11 has a value of 220µF / 50V because I had 8.28V

You write: ZD14 and ZD15 I still have "old". I do not know the value to prophylactically replace, because on the second MIP pin 0V, and here it should be 1.9V on pin 2!

You write: MIP 8 pin 0 R to ground (short circuit). There should be 1V, you have something thrown before Ic2 on the primary one so that you would have to analyze it from the beginning, but I did not draw it because there was no need because Ic2 worked correctly for me; if you would draw it in detail from the network to Ic2, each element with a tortoise's trail, maybe we would find damage after measurements and there would be something more for posterity ...
I corrected TONI_2003

Hello.
You are right here the post earlier I misspelled ZD12, it was obviously about ZD13.
In the meantime, I ordered a new MIP, the new one between pins 7 and 8 does not have a short circuit like the old one. However, with the new MIP, after connecting the power supply, ZD17 burns - the green led stops burning and only the voltage on the 5th pin of the mip remains.
I observed on the old mip after turning on the 230 ~ V power supply, you can hear such a "twitch" from the L2 transformer. In general, I have probably had 4 such chargers from the company and each one was a relatively simple fault to diagnose, while this case is really time-consuming and interesting at the same time. In the evening I will check what you wrote about and edit the results here.

After playing with the change of the old/new mip, at some point the green diode stopped lighting up ... back to the beginning. I ordered zeners and am waiting for the shipment.

Good day everyone, I'm new.
I have a problem with the Hilt C4/36-350 battery charger,
in the input section where the TRIAC is located, I have already replaced the BTA12-600BW Triac and the PC1 optoisolator (MOC3036). I realized that there is the cascade of zener diodes ZD1, ZD2, ZD3, ZD4, ZD5, ZD6 which is faulty. Unfortunately I don't know the voltage of these zener diodes, the only one is ZD6 which, when tested, I measure a voltage of 15V.
Can you help me?
Some of you have the values of these diodes?
Thank you.

I attach photos.

What values of Q10 , D8 , ?

Hi, thanks for answering me.
They are not Q10, D8.
I would need the value of the zeners ZD1, ZD2, ZD3, ZD4, ZD5, ZD6. I have attached the photo with the position of the diodes highlighted.
Thank you.

Photo with zener diode position.

Hi. I have this charger. A few days ago, it completely died. I fixed it now and the LED is green light. But when I plug in the battery, the relay cannot work and doesn't charge. I tried different batteries but it's the same. L6599 is fine. Can anyone help me?

>>20594619
Hi, double check, because in my case Q5 is a MOSFET type BSS138N marking SK𝚜. I attach the diagram with Q5 and components connected correctly.

Can anyone help me with the voltage of ZD14? @ElektrodaBot

C4/36-350 charger C3 cap got separated from PCB
Damaged parts: R36; Q3; Q4
No voltage on IC2 pin 4 source ZD14 dead short
Need the voltage of ZD14

Added after 16 [minutes]:

Hello, the value of Zener ZD14 is 11V.

I would need the value of the resistors R24, R30, R33, R38, R39.
Thank you.

Listen up!!!
Because the charger mentioned in the topic is so popular, and there is such a serious damage that you cannot deal with, I propose to help you all.... In order to do this, I ask you from the forum to be someone kind enough to provide me with one unit for analysis on which I could test and help others to solve the problem.... Preferably with a battery that can be very weak as long as it is detectable.... Who will send such a set to me, I can help him and fix his other chargers.... I see on the forum that each of you asks something new and it is impossible to examine everything, but if I had such a kit to test, together we will solve any problem and there is no charger that cannot be done. Write to me, then I will be happy to help individually.... As soon as I receive such a set... about which I will inform...

And mine when plugged in flashes green and goes off and in 5 seconds flashes again , on the MIP circuit on the 5th leg I have 208V above they wrote that it is 320V ? Mine was shot all the primary section black I replaced a lot of parts L65 chip...all the small stuff around all the zener mosfets ....ech resuscitation of the corpse on the 4th leg of the MIP is supposed to be 13V and I have from 5V to 30V rising and falling to zero I have not yet traced the short circuit , on the thermal imaging nothing lights up anymore

Hello. I also came across this charger for repair, in my case nothing lights up and doesn't work, the LED is dark, I can't see anything burnt at first.
I really like your approach with providing the drawn diagrams and your willingness to help, so I will also try to contribute something useful to the topic as the repairs progress in my case. I have just started the repair and first of all what I noticed while analyzing the board and your diagrams:

you have drawn the end of the diagram incorrectly (the ZD6 anode is connected to ground). Here, your friend drew it correctly, with the fact that the transistor is Q10 and not Q5 (q5 is bcp54 and is in a different place):

Hi, check carefully, because in my case Q5 is a BSS138N type MOSFET with the marking SK𝚜. I am attaching a diagram with correctly connected Q5 and components.

In my case, the Q10 transistor is just shorted (kE or source-drain) and I don't know exactly what transistor it is, I think it's actually BSS138N marking SKs

For clarification, additional information
I have a charger again, and this time it's actually damaged from the ground up.

Q10 is BSS138N marked as SKs, i.e. 60V 230mA 3.5Ω N-Fet channel;

Note occurs:
the most popular BSS138LT1G marked J1 and has slightly weaker parameters 50V 200mA 3.5Ω N-Fet channel;
but we also have a more powerful player than the original, i.e. BSS138W 60V 280mA etc.

diodes ZD1 to ZD5 are the same and they definitely have 15V because I checked, they may have above, but the laboratory power supply was temporarily missing, and the larger one is temporarily grounded because it is in a different place when needed;

the ZD6 diode is probably 5.1V because that is how it is measured, but I will determine it later;
I have a damaged D15 diode with "13" printed on it, according to the SMD circuits page it is a 13V Zener diode in a SOD-323 housing; but in my opinion it is not a Zener diode because it would be printed on the ZD board; it's some kind of rectifier diode but I can't determine the specifics;

damage to the Z15 diode and the Q10 transistor blocks the operation of the Triac and it does not charge the main capacitor;
continued soon...

Mine had burnt R24, R30, R33 after replacing it with 1R. They continued to burn. Pre-measured diodes, none of them show a short circuit. Do you think I 2 should be replaced?
