Problem with my charging system ???
|
Yves Desilets
Hi again,
This time, I'm confused with the readings of voltage on my SG II. Recently, I had my charging system and battery tested by my mechanic. The diagnostic shown on his device (electronic application) was that everything was working correctly on my EV. But that's not what the SG indicates when I'm on the road !!! In fact, the voltage reading is always around 13,1 Volts and sometimes indicates 12,9 volts. I was thinking that my alternator was not charging correctly 'cause somebody on a Rialta Group here in Canada told me that his SG was always indicating 13,5 Volts while driving, no matter if lights, radio and AC are ON !! So, is there a problem with my charging system even if a diagnostic showed nothing wrong ? One thing I noticed is that my engine battery tends to drop a bit over time to 12,3 Volts, especially when I don't use the van for a week or two....Thanks. Yves '97 EVC Canada |
¿ªÔÆÌåÓýHI Yves - I had a similar problem with my ¡¯97 EVC and traced it back to the coach battery low voltage. If the coach battery voltage drops, it will pull the whole system voltage lower while running as the alternator attempts to charge both batteries. This led to me to discover that the Magnavolt house charger system/inverter was inoperative. I replaced it with a newer inverter (as per Michael Diehr¡¯s helpful blog posts). As a precaution I also replaced the solenoid that connects the coach battery to the alternator while running. The solenoid connection points were rusty, as were the grounding bolts in the rear of the van for the inverter.I do also try to keep the coach battery charged during long periods of resting.? Hope this helps,? Alex

Yves I don't know what's going on with your charging-battery system, but if your not driving it very often, get a 'battery tender' for either the starting battery or house battery or both. The battery tender will keep them in top shape, fully charged, even desulfate them. There are all kinds available, just be sure the one you get is applicable to your batteries.
