and why assume that the BandC is delivered with plated (i can
=99t remember with what) replacement connectors in an attempt to carry more c
urrent without overheating, per their instructions.
I have no idea if they are effective, but mine are not (yet?) charring fwiw.

Set your meter to AC voltage and measure from the main bus to ground while t
he engine is running. If you see more than one volt in the AC scale, suspect
a blown diode inside the alternator or possibly bad brushes. Remember, the a
lternator is only supposed to output DC voltage. This isn=99t a perfec
t test, but it is quick and easy. A ripple meter is an even better way to ch
eck stator and diode condition, but most amateur builders will not have one i
n their toolbox.
