Car Charging & Lighting: Starting Car with Charger Connected, 16A Rectifier, Diesel Battery 60

Question

CYou can start the car with the charger connected and charging the battery. I have a 16A rectifier and the car is a diesel battery 60.

Oh, I gave enter too quickly.
As for the question - will it not cause some confusion in the car's electric fuses etc.

goldwinger · Answer

It's not good for a rectifier

lanzul · Answer

Probably not too much.
There are special chargers based on gel batteries for this.
Remember about the starting currents of I = 150 A, for example: the Polonez starter has a power of 1.5 kW, with a voltage of 12 V it gives I = 125 A (easy to calculate, P = U x I).
When it comes to emergency starting the vehicle, I suggest buying a starter battery (gel with a built-in charger).

Are you running a hypothetical car or a specific one? What are the reasons for this launch? Little problem under average conditions. But if you cause a large voltage drop in the installation, the rectifier will try to equalize it, which means it will run at full power or exceed it. And now, if the rectifier has any protection, it will work. And if not, it will be damaged after a longer load. And if the car is equipped with electronics, it may revolt due to sudden voltage changes.

Hello
It's not a hypothetical car - it's a 1994 Ford 1.8d no electronics, simple. Almost always in the morning I have to crank the starter for a long time to make it click and the battery sits down. So I came up with the idea to start the car with the charger connected (Safe Rectifier Set 12V to 200Ah).
Today I was at the mechanics to check the pressure in the cylinders and it turned out that all of them have perfect pressure, the glow plugs are ok and the injectors are also ok - so there is no fuel. But with long shooting - it lights up and the battery crashes.

Such firing with a connected rectifier is a commonly known and used procedure. Unfortunately, it doesn't help. In this way, the starter will not spin any longer or faster and only, as colleagues wrote earlier, can damage the rectifier.

Or there is simply no electricity - battery and accumulator to be checked.

lanzul · Answer

[...] ... so there is no fuel ... [...] If so, you must start with the fuel pump rather than the electrics ?!

Mr.K · Answer

It often happens when the battery is old and has lost its capacity, in order to eliminate another defect, replace it (borrow a good battery from someone) you will see it burn or buy a new battery.

neo_dc · Answer

Put the check valve on the fuel line - fuel should stop flowing back into the tank.

Increase the weight on the engine and repair the starter, you can also manually (I think there is such a pump) pump up the fuel with the ignition on, turn the ignition off for a while and try to start again.
