I have a Valeo CH8 alternator
and the stock Volvo alternator
on my Volvo
. Both alternators have a whole swack of wires on the back of them. Recently I noticed that the positive power cable had come off the Valeo alternator. Upon closer investigation someone had used the wrong size lug (too big) and just tried to crimp the snot out of it to hold the cable. Of course, with time and vibration the cable fell out. I purchased the correct sized 8AWG lug and crimped properly and reinstalled. Now getting to my problem....
I'm only getting about 6 Amps charging
when the engine
is running and I don't know what's wrong. The boat is French and came with a battery monitor
made by Thira Electronique. I can't find an English
manual for it and I don't know whether or not to trust what it's showing me but it shows me the house bank voltage, current
going in/out of the batteries through the shunt, and how many Ah's I'm down. So yeah, when the engine is running at night and the wind
aren't pumping anything in, the engine alone is giving me 6 Amps (all power consumers off). In the day my solar
was pumping out 6 Amps as well and the battery monitor
was showing a combined whopping 13 Amps! The Valeo alternator is rated at 14V, 60A. I know enough not to expect anywhere near rated output but 6A vs 60A is a bit much, and what about the other alternator's output?
Some more information to ponder. When I put my volt meter to both alternators I was measuring 12.75V and 12.88V. This is when the battery bank was down a lot. Later I came back and measured again when the bank was up a bit and I was measuring 12.95V on both. Still, doesn't this seem low? Then I have this clamp on meter that measures current
, although I know the unit is broken so the readings it provides aren't accurate, but when I clamped it on the stock alternator it showed current but on the Valeo it read 0A which leads me to believe the Valeo is not putting out anything. Could it or it's voltage regulator
been damaged when the cable fell off?
Any idea how to troubleshoot this?
Any assistance would be greatly appreciated. I'm a beginner cruiser that's been hit with a bunch of problems at the same time and I'm trying to dig myself out of these issues and CF has proven to be a great resource. I truly appreciate everyone's help.
