    Greetings to everyone, my Hilti C7 / 36-ACS charger doesn't want to turn on anymore. I found fuse F1 blown, and transistor Q2 shorted. Can anyone help me with the wiring diagram?

    P.S. Sorry for my bad English. HILTI C 7/36-ACS 230V Battery Charger Not Turning On: Fuse F1 & Transistor Q2 Issues

    Hello,
    for what do you need wiring diagram? just replace faulty components and try if it works.
    I would check also at least this big capacitor
    Good luck

    Hello - the electrolyte is probably damaged, please check.

    Hi,

    Can you please tell me the name code of IC1?

    Many thanks! šŸ™

    It looks like the plastic cover from the big cap is "peeling" off from the top, this is the sign that the cap needs to be replaced. The "peeling" may be from the bottom also. Replace that cap too

    Hello,
    Check also the resistors near the transistor, especially one that is the shunt (low resistance). Always use a 500-800 Ohm resistor to discharge the big cap before replacing it.

    Hi I have a problem. When I plug the battery, charger starts, fan works and after 10 seconds charger stops. Did anyone solve this problem? I replaced L6599AD IC and MIP2M2 IC but same. Relay, triac, mosfets, all zener diodes good. Battery is good. Anyone can help me?
