Thanks for the updates guys. The batteries are all brand new as of 2 weeks ago. My old ones were going bad so I replaced all of them at one time. $430 for 4 series 37 batteries. 18 month full replacement warranty and 36 month prorata warranty. I just priced deep cycle batteries for the house system, optima gell cells, $199 each.
The vanner looks like it is working well. I didn’t think that the lose of volts from the rear at 12.56 to 11.87/11.74 at the front lights was that big of a deal but appaently it is. I will go chasing the wire but it is bundled in the PVC tunnel, so may not be possible. May just have to run new wires to the relays.
I will continue to look for the reasons for the erratic voltmeter fluctations if someone has any ideas where to check next, but I, not being an electrical expert by any means, don’t know where to look next.
