Angry USE/STORE switch failure

The 12-Volt supply shut off during a camping trip in our Four Winds 22E motorhome. I discovered that the Intellitec Battery Disconnect Relay 01-00055-002 had burned out. It has gotten hot enough to burn the flooring where it was mounted. But the real problem was the momentary USE/STORE rocker switch was sticking in the "STORE" position causing the coil in the relay to heat up (and also discharge the batteries). Eventually, the relay failed caused by the stuck switch. A temporary fix for the switch was to pull off the rocker and push a small amount of SuperLube Silicone Dielectric Grease into the switch mechanism. The permanent fix was to replace the switch with an identical one (American Technology Components #AH-ASY-1-5-039, Battery Disconnect Switch, SKU # 78739394420) that I found at pdxrvwholesale.com. It was a costly failure to replace the relay and two DC27 Batteries all because of a bad plastic switch.

At least it was a problem and a solution and not just a: How come my solenoid is burning up question?

Welcome to the forum. You state the coach is a Four Winds but you don't mention the model year. Is this a newer coach or something older? Knowing this might (operative word) help others anticipate an issue in the future.

Thanks for the write-up.

You only see a user name, join date, location and posts, so placing pertinent info in the write-up helps those viewing from an iPhone.
