My favoret hobby: trying to understand all the bits and pieces of my gmc
I have this idear that the alternator is not charging my house batterie as good as should be. I had this feeling for a long time
I have a smart combiner cyrix. And I just installed a victron bm 700 batterie monitor
The batteri was down 60Ah when I started the engine. House batteries were charged initially with 18 A. On idle. Then I drove of had my light on and drove for 2 hours. That only charged my house batteries with 10 Ah
Now I try to understand what happens with the alternator. It has the sensor to the + distribution point. Now does the alternator stop charging when the starter batteri reaches a certain voltage ? Thus not charging the house batterie? Or is there just to little left with lights on etc to charge the house? No aircon, no invertor running. Fridge on 12 volts
Does a alternator loose power when it gets old?
Is a100 A alternator a straight swap ?
Thank you
