Fired up the generator after 5 MONTHS of sitting. I neglected to plug in the battery charger, but the batteries were at 12.4 and 11.8, which was enough to get it done. Gen fired off, and I tested out heat and AC. I replaced a fuse in the battery charger and ensured they worked. My red top Optima's handled it great. Going to check on them in a day or so to be sure they aren't boiling away, but in the 2 hours they were on charger, no issue. I think I got lucky. Also got my replacement support leg on it. I am doing surgery on the old leg, it was banged by some hammer and dimpled the metal making it hard to extend. I also tightened up the fan belt, it was flapping around. I think I will need to replace as it's at the end of it's tightening travel. Good day!
