We purchased a shasta class c motorhome. This is our first motorhome. We hooked it up at home to the electrical so we could clean it. When the electric was on or even plugged in if we touched any metal on the outside we would get a shock. I even got shocked when I tried to lock it. I had to go unplug the electrical cord and then lock it. We were using the cord the owner gave us and we tried another. Also the a/c would run but no air would come out. I don't know if we are missing something. There are no manuals for the motorhome. We bought it from an older couple and they are looking to see if they can find them. We are set to go camping Sunday and need to get this figured out. Thank you for any help anyone can give.
If you still had the problem with the other power cord, you have a problem in the main power cord or the circuit breaker panel, and your MH is not grounded, either by your cord, or the outlet its plugged into. I recomend you pull the plug until you get it corrected, dont wait until tomorrow.
You will likely need a VOM meter to track down the problem, and some electrical experience will go a long way, if you dont feel comfortable doing it, get some help.
It could be something vary simple, once you find it, and it may not even be in your MH, have you checked the house outlet for polarity and ground?

I think that the ground wire on your power cable has become disconnected. Look where the power cable attaches to the motorhome and be sure all connections are attached and tight.
Ground is not connected, and hot side of power could be leaking to the MH chassis.
The problem could be anywhere in the motorhome 120V wiring. The problem could also be in the outlet you are using for power supply. That also needs checking, many homes have wiring problems, especially older homes or after DIY electricians play with the wiring.
Shut the breaker off to AC unit and see if that cures it , Years ago I had made MH hot by trying to reseal roof top ac seal.. pinched 110 wire up there against the metal roof.
No matter whats wrong, if your getting shocked when you touch the outside of your RV, its not grounded, and this is the first problem you need to correct.
And when you do, expect a breaker to trip some place, in the RV or in the house.
You have current leaking to ground in your RV, or its power cord or power source, but its not grounded, and its sitting on rubber tires, that's why you are the path to ground for the current, and get shocked.
This could be vary serious and dangerous, pull the plug now and have it fixed ASAP, before a little kid touches it in the rain.

Ditto Ditto Ditto on Cool Mike's comments. If you have a "hot frame" and are not popping breakers, you have lost ground. This is a very dangerous situation and needs to be looked at NOW.

thanks to all who posted. We were on vacation and I couldn't reply. The couple came out and found that the air conditioner vent had a squirrel nest in it. We thought that solved it but later the shock came back. I believe it was what you were saying about the ground. My husband was making some changes to the electrical, we bought a new cord and such. He found that it wasn't connected under neath. Thank you all again for your responses. We had a great first trip with no problems. We are planning two more in August. Take care
