I'm helping a friend with his '70 Sovereign
and we're working on the AC right now. It's got the TAC110-1 unit with the wall thermostat and no heat strip. The condensor fan works just fine, I believe I'm getting 24VAC at the transformer (it hums, and need to reverify it when I head back over today), but the compressor does not even attempt to come on. I can do auto AC and have never ventured into these types of units, but I've been reading this forum for hours and have picked up a few things.
Next steps for me include:
-verifying that we're on a 30A circuit
-verifying the transformer output voltage
Everybody seems to center on the start capacitor (the 25 uf one), and I'm good with that since I measured continuity across the terminals and no capacitance. I've also measured no capacitance on what I believe to be the run cap (the 43-53 Mf can with the resistor).
All that being said, I know that a few people on here have found modern equivalents for these parts, but I have yet to see the part numbers posted. For posterity's sake (and my own selfish reasons), could anybody post what they're using as replacements or what their research has turned up? Thanks for any and all help.
