It’s a deep cycle battery and yes I definitely did not measure it under load .   The lights come on and function as expected .   I charged this battery on a solar panel,  but we don’t use that for anything else .   Stove is from the 70s, just straight propane .   I’m new to this , taking over for the father inlaw who’s not able to help or advise anymore . 
 

will get some more clues after this coming weekend .  Many thanks everyone !!!  

Yes my mistake, definitely should have gotten the model # , will do next time ( 2 hours away ) .   I did give everything a pretty thorough clean.  Battery is 12.3V and propane works on stove, although I’m not sure that equates to adequate gas pressure.  
 

I didn’t look closely at the igniter for hairline crack, and don’t think this one is adjustable for gap.   We have no access to AC as fridge is in a cabin off grid and without a generator .  
 

I don’t smell any propane while I’m waiting for it to lite, is that normal ? 

Not sure of the model number , but we only have access to propane so we can’t test the AC on our fridge .   Normal operation, you turn it on and it will fire the igniter up to five times and then break for awhile before repeating .    Currently it only fires once, doesnt lite and then won’t attempt to lite again .   Any suggestions?
