sorry about the delay. I'm now having an internet problem. It seem ok for the moment.
I open the little black junction box beside the compressor. the white wire from the 120vac goes on a terminal that says PLC Starter according to the little diagram on the label on the fridge (I just noticed). the black wire of the 120vac coming in goes to the thermostat. the other side of the thermostat goes to another terminal that's on the compressor. the other wires inside the junction box are all black and they jump between different terminals on the compressor.
does this help?
the suppco spp6 only has 2 black wires.
the spp6 says on it "relay and hard start capacitor".
here is what it looks like:
so i unplug the black wire going to the compressor coming from thermostat and plug in series the spp6?
this should work, try that. you say its running now do you think you should wait and see before doing this?
the fridge only runs when the alternator is running, otherwise it triggers off the inverter. I will try plugging in the spp6 as you say. thank you for your help!!!! I will try this later tonight. THANK YOU BRYAN!!!
