Let me know if you are in hookups.
Batt. was at near full charge, pushed by two Trojan 6V...same issue when I hooked up the generator. im really thinking it is an internal furnace issue, a switch of some sort or an igniter. anyone had a similar issue and a result that I can look at.
Great talk, thank for the hint, keep em comming
