Atwood G6a-8e

[damammel]

I have a 6 gallon gas only Atwood water heater in my 2016 287bhsw. At the end of last year i had an issue with no spark but if I lit it with a grill lighter it would start and come up to temp. After I would need to light again if it needed to reheat the water. I followed the online tests and found the lamp track(blue wire) in the board was bad. I replaced the board and everything worked. Just started camping this season with the new board installed. Tested at home and it was good. Got to the campground and used it one day. Now I have no gas or spark and all circuits have lost continuity between them and the ground terminal. I’m going to clean the ground off well before installing another board but I didn’t know if anyone has come across something like this. Btw I installed the 1st problem board and I’m able to light it and keep it going. 2nd board won’t keep the gas valve open. The fuse is good in both boards.
