well the battery cables go into the battery control box... and I cant find any other wires to trace (I did find two large red wire going off and up and under the vehicle, ground muddy, not crawling under a car that is not mine in the mud LOL I am a 55 yr old disable female... as my excuse ;) ). I tried the neutral thing too and still nothing. The battery light and the check engine light are the only things that light up (besides Odometer)on the dash. I put the charger to the 100a jump start and still nothing.
Main battery at 12.9v, charger says fully charged. but have the charger on one of the other batteries again and will just try charging both those batteries and see if anything happens after they are both charged and let you know. in the meantime, I will see if I can find a repair manual for it online somewhere to see what is what...
Knowing my luck, it needs a repairman to come fix it and this one is not mine; I was letting a lady store it here and she was supposed to come get it today (but I have not heard from her in over a month).
Time will tell but I am wondering if in 3 months, I will be starting the paperwork for a lien sale....
(and, it has not started for over a month, I just joined today looking for some guidance as my fulltime RV is a vintage VW bus. Now THAT I know how to fix....)
