Lunaire TSC-16H Schematic

Does anyone have a schematic on an old Lunaire air conditioner model TSC-16H? I have a Trojan 10 Meter and having issues with mine tripping the GFI circuit at my slip as soon as I turn it on. The heat index today is 110 degrees!
Any help or guidance would be greatly appreciated.
Thanks, Mike

I have a 1986 10 Meter mid cabin with a lunair system in the front cabin, mine has a wiring diagram on the A/C assembly. Are you tripping a 30 amp breaker for your power cord or do you have a 20 amp GFI outlet. If it is a 20 amp GFI outlet I would try a different one, if it is a 30 amp circuit breaker that sounds like a short somewere on the A/C unit or a bad compressor in the unit.

Thanks for the quick responses. I am tripping a 20 amp GFI circuit. It was working fine for a couple of months and would only trip the GFI occassionally, but now it trips every time and turns on for less than a second. It is a brand new receptacle and the wiring is also new there.

Is it possible to get a copy of the wiring diagram you have on your A/C assembly or maybe even a picture if it's not removable?
Let me know. Thanks, Mike

I did not know any one was still using 20 amp shore power most marinas are 30 or 50 amp as thats how most boats are set up , and most have no ground fault are you sure your a/c is just not overloading it on start up ? a bad start capacitor could do that.

I have the unit pulled out and will test it on a 30 amp circuit and see what happens. I'll check the starting capacitor too...good idea. Thanks.

GFCI circuits will go bad over time with that much load on it. Remember 20 amps at 120volt times the lenght of the circuit, you will get some voltage drop.

Mike, My A/C unit is mounted in a enclosed compartment there is some disassembly required to get to it. I am going to rock hall this weekend so I will not have time this week but maybe next. I was also looking for my original trojan manual to see if there is a wiring diagram in there.

I took some readings and found the motor start capacitor to be bad. I'm replacing it today and will run some more tests. Thanks to all for your help and suggestions. I'll let you know how it turns out. If you do find that diagram and can share it with me, that would be great.

Mike, were you able to get a copy of the schematic off of yours?
I replaced a faulty relay on my AC unit also and it turns on now without tripping the circuit, but the compressor will not turn on. I had to cut the wires on the temp sensor when I pulled it out but spliced them back together. Will a faulty sensor make the compressor not turn on? Can the sensor be bypassed? I want to jumper power directly to the compressor motor itself but not sure which color wires to go to on the terminal block. There are quite a few wires that go into the compressor at the bottom.
Thanks again to everyones replies. Mike

Hey Mike I have not had time to pull apart that compartment, I will not be down this weekend but I will try to do that on the weekend of the 20 if you need it.
