Thanks Drew, Dee, and Kevin!
Yes, I definitely plan to add a thermal switch to the replacement motor on the rebuild -- hopefully to prevent such a thing from happening again, ugh!
Mike WA6ARA suggested a company down in LA that rewinds motors -- I sent them a description, and they wrote back at 11pm last night (!) saying that there would be no problem with this one, but to send it down so they could take a look and give a quote. So .. the defective motor is on its way down there now.
I'd still like to get a replacement of some sort, whether or not the rewind is successful -- can anyone confirm if the G5400 azimuth rotator motor will physically fit in the G5500 gear assembly? I know the capacitor is inboard in the '5500 and at the controller on the '5400, but are the two motors physically similar?
Thanks everyone!
