Lost AC Power

Hi All,

Another adventure with my Alpine Coach. We were out at Cuyamaca Rancho State Park hosting the annual family camping trip (20 attendees). I started the generator and after the delay, I heard the relay clunk but no power transfer. After checking the gen set circuit breaker (it was ok--not tripped), I shut down at re-started with the same result. However, this time I noticed the display panel for the RV Surge Monitor saying "Open Ground".

After some discussion with my brother-in-law (an engineer) we decided to check out the mysterious black box called the Transfer Switch. After removing the side inspection plate (gen set OFF), a flashlight inspection revealed a disconnected ground wire on the output side. The copper conductor had come loose from the connector. We wiggled the wire back to the connector and tightened the screw. Re-starting the generator all worked as it should with no error messages and plenty of AC power.

I'm sure I saved many dollars in not having to replace a fully functional transfer switch whose only problem was a loose ground wire!

One of my not exactly jokes that I like to type goes like this:

Many RVers have a few screws loose... Like the one in your transfer switch.

You might want to check out the breaker box some time when you don't have 120vac about... I found a bunch of them there too.
Home is where I park it!

When you have a chance--check out the thread on loose wiring. Places to check include both AC and DC curcuits and include the genset itself, the junction box above the genset area [bottom of floor{ceiling} between driver and passenger], xfer box surge protector--if separate, all the breaker/fuse panels, and other places like the junction box under the bed in the 40ft TSs. Doing this check once a year or so wouldnt be too often--our rigs do a lot of bouncing around.
