Water heater would not fire - a lesson learned

[BurgPath]

Dewinterizing my 23SS today. Flushed the system, installed a new filter and filled the water heater. After testing out the gas I tried to fire the water heater. No click, no noise. Red light next to the switch stayed on. I tried hooking to 120V while troubleshooting, system wouldn't fire.

I'll save you the long story of my failed attempts to fix this.

Found a blown 30A fuse in the fuse panel. Replacing it caused it to blow right away. Took me a bit but I finally found my error. When I installed my new battery I reversed the + and -. Odd thing is everything worked when backwards even the lights.

Reversed the cables, installed a new fuse and the system worked as it should.

Glad it wasn't something major wrong but amazed I missed something so simple and obvious.

Unless lights are LED they they don't care which way there are connected. Slide and awning might work backward from normal.
