Thor Vegas 2017 Electrical Issues

[rvtravel]

I have a 2017 Thor Vegas 24.1 purchased used 2018. Recently noticed converter had no fuse in the #6 audio/video slot. I inserted a new 15 amp fuse, began to have following operational electrical issues:

LED lights around the headlights stayed on.
The awning did not work.
Slideout did not operate.
Front window shade stopped halfway down, did not completely close.

Vegas hooked up to shore power/house and in USE engaged. Engine battery replaced before issues started but just noticed missing fuse.

Without the fuse, awning and slideout are operational.

Rear radio turns on when 15 amp fuse inserted. When audio/video fuse removed from converter, radio only turns on when ignition is on or in accessory position. Replaced fuse located in back of radio. Still functional only with ignition on. Previously, rear radio turned on whenever.

Electrical issues checked by two RV repair mechanics but not resolved. Last mechanic replaced the relay switch in back of converter per instruction from Thor electrical specialist. Electrical issues not resolved.

RV mechanic rerouted wiring for the LED lights. LEDs no longer on the 15 amp circuit, now work with on/off toggle switch. Window shade was reset and now functional.

RV inspected prior to purchasing, issues with converter not identified.

My wife and I have only used the Vegas locally in Orange County, CA. We’d like to venture out on a road trip. I want to continue using Vegas as is (without fuse in slot #6), my wife wants to find an electrical RV specialist to fix this problem. Any advice or referrals appreciated. Roger - Huntington Beach
