295MK 120 wire diagram

Can I please get a wire diagram for a 295MK 120 V
I am getting L2 to ground short on one of my air conditioning units and I want to find out what else is on that circuit.

So, like your and many others(including mine) requests for wiring diagrams have been met with great resistance at Alliance for some reason.
Could you share more about your L2 ground short on you a/c unit? How have you come to this conclusion? What is actually happening? How have you identified the L2 to ground short?
I believe each a/c unit is on a dedicated circuit, so are you experiencing a short circuit on your ac circuit that happens to be fed from L2? Is the Ac tripping the breaker immediately?

I am getting continuity between ground and L2 on the one air conditioner. I turned off the circuit breaker on that unit and noticed that the bathroom gfi outlet is not working now.

I am getting continuity between ground and L2 on the breaker for that unit and noticed that the bathroom gfi outlet doesn’t work now since I turned off that breaker.

It now looks like the bathroom and everything In the bedroom is on the same circuit.

I am sorry, I just can’t fully understand your post. Apologies, it likely just the way my mind works.
Could you share the following?
Forgoing electrical checks, what complaint are you chasing? Ac doesn’t turn on, breaker tripping, what specifically caused you to start your investigation?
What specific wire or connection are you calling L2?
You indicated you turned the breaker off and lost other circuits, a ground to a true “L2” would be a direct short and would have tripped the breaker.
Your AC would be 120 v AC so the three wires involved would be Hot, Neutral, and ground. Yes, the hot would be fed from either L1 or L2 on the breaker panel.
Sorry for playing twenty question here, I am only trying to help and might not be able to if I can’t wrap my head around your post details.

Another question you say everything in the bathroom is on the same circuit. Besides the GFI what else is 110 volts in the bathroom?
Lighting and exhaust fan are 12 volt I believe.

I agree with Lantley, standard lighting and fan would be 12 volt DC.
The other thing I can’t get my head around would be the bathroom and AC unit being on the same circuit. The Ac by itself is going to pull @13 or or so amps by itself, so if someone would try to use a blow dryer or curling iron on the bathroom circuit, the draw would certainly exceed the breaker rating and you would need to shut off the ac to use those circuits.
More questions than answers, sorry!

I plugged my circuit analyzer in, and the power looked good. I then plugged the trailer in and noticed a red light indicating reverse polarity. When I touched the power post lid, I got a shock. I immediately turned off the power post circuit breaker to the RV.

Next, I checked the trailer plug connections—they were fine. I removed the wall in the passthrough to access the power relay box and see if anything was loose, but everything was secure. I checked continuity on the trailer side of the relay and found continuity from one of the 120V legs directly to ground.

I then opened the fuse breaker panel and started checking the power wires to ground. I found the one with the direct short, which turned out to be the fireplace breaker. I turned off that circuit breaker, powered everything back up, and everything worked fine as long as that breaker remained off.

Afterward, I noticed that my bathroom GFI was not working, and I heard a buzzing noise when I pressed the reset button. No breakers tripped when all of this happened.


Could the direct short in the system have damaged the bathroom GFI? I unplugged the fire place and I still have the direct short. looks like the wire that goes the the fire place is touching ground.

I would certainly think damage to the GFI is possible especially if it gets fed from the same leg at the panel. Other things could be a risk as well given the direct short you had. Great work investigating, and good luck finding the actual spot that has shorted out.
Could you keep the forum posted on your findings?

Anyone know how to remove to the fireplace drawer? It looks like the wire needs some slack!
