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
