Forum Title: dead battery charger
Hi-Thanks for having me on. Hoping someone could answer a question on a 6/2 ampcar battery charger that I'm trying to bring back to life.There are three wires from the secondary side of the transformer the two outside (red)wires go to diodes (one for each wire)that are attched to a common bar(heat sink)which is attched to the positive battery clip. The other wire (black) goes to the negative battery clip. My question is, should the two diodes be attached with their cathodes to the bar? Thanks

What you have is a center tap full wave rectifier. The cathode is the positive and should be connected to the bar.

I thought that was right but was alittle confused since there are two wires going to the bar each with a diode.Transformer is also burnt up so can't check voltage on the wires.Thanks for the help.

If the transformer is burnt -- it's dead.Stop.Buy another device.
