I DIDN'T
notice that this was unconnected. I have to look at the
circuit.

So the
voltage drop across the diodes is normal when not connected to the pack? I
expected to see 42V and that it would drop when I connected the pack. The manual
says 40V is OK but doesn't say where, before or after the diodes...

That's not all that far off. 36V into a low pack is GOOD. You
can only source so much current (20 A for the standard charger) and you have to
overcome the pack resistance. Think about it; if you had a dead pack it
would probably take 400A to bring it to 36 V instantly (and that would kill
something...). In time, you should reach 42-45V.

voltage
I was testing my charger
to see if I had a problem with output voltage, I did it with the main disconnect
out. I have recently replaced the capacitor and the diodes. I have a voltage
drop across my diodes that seems unusual. I have 42V going into the diodes, but
only 36V going out?
But if I let the pack charge, the charging voltage
will reach 42V once the pack is charged up...
I have
a diode bridge that I used instead of the stock diodes. I got it from a friend
with a couple 36V EVs (Commutacar and Lectric Leopard) and he assured me it was
well above specifications.
Thanks
