This morning my alternator
, a one year old 120A Iskra, started causing an alarm
on my engine
It is controlled by a Balmar
I checked the field voltage and it looked okay, about 8 volts.
A clamp-type ammeter on the B+ line to the batteries
shows zero current
even though the battery
voltage is more than a volt below what the Balmar
is telling the alternator
Also a volt meter on the B+ terminal shows battery
voltage when the engine
is off, and doesn't increase when the alternator is running.
What I think is odd is that even though there's no output, the alternator heats up fairly quickly. I can also feel it kick in because the engine RPMs change a little when the Balmar tells the alternator to start.
I've searched this forum, and reread the section in the Calder book about alternators, but didn't find anything about an alternator that has no output, but still heats up and bogs down the engine.
Any ideas on what the problem could be?
