timnjulie Report post Posted May 9, 2022 2005 Holiday Rambler Imperial 400 BP diesel pusher type A motorhome. During lightning storm I arrived at Motorhome, entered turning on lights which dimmed (brown out) to almost black. So turned lights off. After storm lights would not work. only plug in receptacles work. I installed a new inverter box, but no change. Removed surge protector and plugged directly to power plug , no change. Looking for ideas. Share this post Link to post Share on other sites

wildebill308 Report post Posted May 11, 2022 What does your surge guard say about the incoming power? Did you check cycle the circuit breakers on the generator? What was the voltage at the plug in receptacles? What was the battery voltage? Bill Share this post Link to post Share on other sites
timnjulie Report post Posted May 11, 2022 Surge shows on and at power pole ok. Generator puts out power. Did not check at receptacles, will check tonight. Not sure on battery voltage. Still need to test transfer switch. Thanks Share this post Link to post Share on other sites
aztec7fan Report post Posted May 13, 2022 is there a chance your coach got directly hit by lightning? there was another thread recently where a coach was hit, and it fried so many systems, the unit had to be written as a loss by the insurance. it was a really bad fight for the owner. not trying to scare you. I hope it's just one fuse, relay, or circuit that needs replacing in your case. Share this post Link to post Share on other sites
timnjulie Report post Posted May 15, 2022 Had a technician come to Campground he discovered the power switch at the door needed replaced. Thank you for your suggestions. Share this post Link to post Share on other sites
