no shore power

I have checked the breaker boxes outside, all good. The inside breaker switches were not tripped but flipped them off anyway, let them sit a few seconds, the flipped back on. Nothing. I have solar and when it is on I have power to all my plug ins. Where else should I check as to why my shore power is out?

Solar should not have any impact on your AC so I donít understand that issue. Do you have power when running the generator? Tracing an electrical failure is pretty easy with a multi- meter. Start at the park pedestal outlet and keep testing connections until you get to the onboard fuse box. Thereís probably a failure in your shore power cable or the ATS.

Yes, I have power on the generator. I have a digital multimeter but do not know how to use it (belonged to my husband). I have the manual but not familiar with terms. Got black plugged in to COM but red has 2 different plugs, 10A & VmAF (some other symbols not in my key pad). There are 4 areas to dial into V, upside down U, Batt. and =A.
Can you help guide me through it? I am parked in the back of a Moose Lodge and no one around to ask who might know.

Just went and bought a new extension cord and that solved the problem. The old one (6 yrs old) apparently Had a short so even tho it had juice, was not making a good connection with my newer cord that plugs into my RV.

Glad you got power back! Enjoy your trip.

Well, if you are not familiar with that you maybe shouldnít do the level of testing I was suggesting. AC current is dangerous and testing wire connections requires getting right down into it. Donít want you to get hurt!

But youíve already made good progress. Since you have power when on the generator you know that everything ďdownstreamĒ of the ATS (automatic transfer switch) is working properly. The ATS is the very first thing on the coach that the pedestal power cord goes to. SO...you really only have three possible problems. First, the pedestal power might not be working - can you try plugging into a different power source? Second, you might have a problem in your power cord - the connections in the ends occasionally go bad. There isnít an easy way to check this without using your meter other than just examining the plug and maybe wiggling it when plugged in to see if the power can be restored. Third is the ATS. It might have failed but more likely there is just a loose connection inside it. Again though there isnít a really good way to check it without taking the cover off and testing. Which is quite dangerous if youíve not done it before. If itís not the shore power Iím afraid I have to recommend you call in the cavalry for a rescue. Fortunately it should be pretty easy for an experienced tech to diagnose. Good luck

The red goes into the VmAF jack for almost all measuring. Checkout some Youtube videos.

Your ATS and almost all your electrical components are under the seat in front of the bathroom. There should be a piece of plywood under the cushion held down by a couple of phillips head screws.

Grad you got it fixed with a new cord. BTW, the old cord was "open" not shorted. If shorted it would have been smoking and tripping pedestal breakers.
