So i'm recommissioning this coach bit by bit. Everything worked at one time, everything sat for several years. During my covid quarantine i got
most of the RV systems working great.

Then i installed a 100 amp gel cell to test the charger and battery life.

SO at this point the furnace begins failing intermitantly, it won't ignite. so i research that a bit and figure it's the sail switch.

Then i plug the AC back in and the furnace lights up. Conclusion- as the battery wore down it wasn't moving enough air to move the sail switch.

I need to install a volt meter/battert monitor.
