Just dropped my van off due to one of my batteries not being right.
Starts fine but the secondary battery voltage is down to 11.8 the next day after a good run & then soon drops to 8 volts once the doors are open & the lights are on in the back etc... It goes up to 14.7 volts when on a run so it is obviously getting a charge.Didn't notice really when it was like this but I did loose my trip settings like mpg & average speed a few weeks ago but thought nothing of it. Most of the time the van is running so everything just works as normal.
I can't believe that with all the diagnostics in the van that this wouldn't get logged & warn me.
Anyone else had this ?
Thanks,
Jim
