    Hello all, I have a Century Car battery charger that I would like to repair. I think that a Transistor is bad, I can't find a parts diagram of this charger, because it's too old according to Century. Model # 6z763B part # 141-291-910. The charger has power until it get ti the circuit board, where, I believe it goes through a Transistor of some sort.

    Thanks for your help, T D & H

    We might be able to tell something based on clear photos of the circuit board. That transistor may be an SCR.

    Looks like an SCR based on the number you provided.

    Datasheet - S1055

    If this is the case the pinout should be K A G (Cathode, Anode, Gate)

    Check this post for info on this device and a simple check you can perform.
    The Silicon-Controlled Rectifier (SCR)
