A few weeks ago had a tech check the batteries in my rig and they cleaned the terminals and said the batteries were sitting I believer around 12.6 volts which was good.
I was at the rig yesterday installing some items so the house batteries were on and I also had the inverter on. Within a little more then an hour the lights dimed and the panel was showing the house batteries at 11.6 volts. I had to start the rig to get the generator started and I let it charge for about 4 minutes then turned the generator off. The batteries were showing 12.6 again.
There is no way there was enough time to charge the batteries in that little time, any ideas on what may have caused this?
