OK, time for an update. Earlier today Greg Ross, who is also attending the Balloon festival, stop by my coach to see if he could help. After reviewing the conditions I stated previously in this post, we looked at the wiring inside the Surge Guard and confirming all connections tight and voltages in spec, he suggested we “reboot” the system by tuning off the generator and turning off the battery switches, which we did. After turning the batteries back on we once again started the generator and it appeared to work properly. I ran the generator for 4 hours while it went through bulk, absorb to float, all worked well. After turning off the generator for several hours I restarted it and it performed as it should. It appears that the reboot worked. Lights and heat for the first time in four days.
