• Upgrade to four 6 volt batteries?
    Thanks for the advice Ray!! That gives me the info I need to get this all redone!!

  • Upgrade to four 6 volt batteries?
    Oh, follow up question: I am reading differing opinions...Should I just avoid CCA wire? I am seeing some good offers on Amazon, but don't want it if it is unsafe.

  • Upgrade to four 6 volt batteries?
    That great Ray! I won't worry about that then! :)

    After watching your battery upgrade video, I've also been thinking I should upgrade my wiring for everything. When I first installed the inverter, I just used the wires they included. After watching your and Eddie's videos, I am sure that what I have (mostly #4 AWG) is undersized! I have a 1500 watt inverter (with a 3000 watt surge) and am not sure which gauge wire I would need. Do I need to account for the surge or just the continuous? I would think the continuous should work...but wanted to double check.

    If I understand it correctly 1500 watts / 12 volts = 125 amps.

    "The Google" tells me that #2 AWG Copper and #1/0 AWG CCA wire would support 125 amps.

    Does that make sense? Or should I go bigger?

    Thanks so much!!
  • Dometic Fridge not turning on
    Just a quick update on my issue: Ray you were right, it was the control board that was the issue. A quick click of the Buy button on Amazon and this part and a few minutes to install and all was right in the world again!!

    Thanks for your help!!

    :groan: Yikes! I guess this is a harder problem than I thought! The only thing I can think of to try next is to replace the control board on the outside panel. I'll try and swap that out and report back...

  • Doing the thermostat least trying...
    Thanks Ray!! I think you know everything!!! :up:

    Thanks Ray! This confirms the info from your first link. I feel more confident redoing the new thermostat install!!!

    I am still a little concerned that the AC didn't start when I connected the green and yellow wires though. Is there possibly another fuse to check other than the breaker? Or am I wrong in thinking that the compressor would start up immediately if I connected the wires?

    Thanks again!!

    Oh, forgot to mention that the I checked the AC breaker and it looks good. Also, I am on shore power.

    Ray, that is awesome!!! Yes it is a Duo-Therm by Dometic. I should have included that. That certainly answers the big question!! I really don't understand it, but it seems the green wire is the hot one! Not sure why it was plugged into the GRD on the original thermostat. :chin:

    Starting over, I unwired everything and just tried the green wire with each of the others. The white wire started the heater as expected. The yellow wire (ac) did nothing...strange. Shouldn't this start the AC?

    I didn't put the green to the red...I feared fire or something...

    Afterwards, I thought that I would go way back and just reinstall the orig thermostat, to make sure that I didn't ruin anything. Everything seems to work fine including the low and high fan. I cannot test the AC because it is too cold in my shop for it to kick on.

    Anyway...I am stumped. I'd greatly appreciate any other thoughts/suggestions.

    Thanks again for the link!!!
