Just wanted to let everyone know I sorted out my electrical woes (at least some of them) turns out I had faulty ballasts in the lights
and a dead motor fan. Bypassed the ballasts to convert the lights
to LED, and found a cheap motor replacement so I am good to go there. The swamp cooler and furnace
are still inoperable, but I will get around to them by and by. Anyways, thanks everyone for the advice, support or caution. Best.
