    Gents,
    I figured the best way was to copy the troubleshooting in the Merc-O-Tronic service manual, so that is what I did. Then broke it down to test a single diode, then complete the circuit by adding the anti reversing switching. This I added so a guy would know to trouble shoot as well if no charge was shown, All part of the charging circuit. Frank, Wasn’t inclusive of the bridge test but completing the charger circuit testing if this wasn’t known. We need to remember the early bridge was light years better than was on the market at the time as an alternative rectifieing full wave circuit.
    If it was me I would not even test. I would get a new bridge silicone diode set for reliability. Then again I have a selenium bridge in my Merc O tronic built in Canada & it functions well. But no heat or vibrations to deal with.
    It’s all so elementary! electricity will pass one way & not the other, basically. Reverse the leads & the diode reverses output…..It’s a one way valve. But then we could get into ripple voltage & add a cap to smooth that out. Mercury charging has no regulation with the older units & no frequency blocking for the radio either. All in the eyes of the beholder I would agree, I love a debate discussion. 😀
