i have a heavy duty cig lighter plug with alligator clips that i'll be trying out connected directly to the battery. otherwise, the positive is the center and negative is on the outside, if you have some test leads that are heavy enough gage wire, you could clip those to the plug.ok dump question. by looking at a cigarette adapter plug how would i hook up directly to the battery?
not sure if it will help or not because my battery is only putting out 12.5 volts, where it should be making 12.8 or so. if that doesn't work, i'll hook it up to the 48 series in the g/f's volvo, if that doesn't get the thing running right, i know its the fridge.
thing is, it seems to do fine if the truck is running and i hook it up. it seems like something about starting the truck with it hooked up throws it off. maybe its tripping the low voltage cutoff and turning the compressor off?
i pulled the cover off last night to see if there is anything obviously wrong, and didn't find anything other than the power wires to the compressor controller weren't seated all the way down on their spade connectors. started it up and set to 20f, checking the temps at various intervals. i started at about 4:45, and it took until almost 10:30 to get down to 22 degrees. is this normal from what everyone else has experienced? it stayed at 30 degrees for over half an hour as well, while the rest of the time it was dropping 5-9 degrees every 15 minutes. any ideas why it would do that?
