Great video! What would happen if the potential relay was stuck on and kept the start cap on the circuit? Would the compressor be ruin immediately? Is a 5 2 1 hard start kit on a otherwise normally working compressor too much of a risk to use? Some HVAC technicians recommend it to extend the life of a brand new compressor while others warn me of the dangers of ruining a normal working compressor if the run cap or potential relays fails at some point and by the time it happens, it would have been too late.
You said it was a pain to check the start cap because of the bleeder resistor but you didn't explain how to do it. I know how to check a run cap but is checking a start cap different because of the bleeder resistor?
