No I can not lol. Maybe try another cap. I got on once new that turned out bad and I put the old one off another unit back and tested it and all was good. I got two I can sell you cheap that are only 14 years old,,,,,

I did try another cap 2 in fact

With new caps in place, read draw of compressor. Still bad, another unit. They do sell units that are more robust. Probably built like the old ones.
Funny you had two go bad at same time. Is the voltage to all three units staying the same when running? Problem with a leg of the 50 amp source?

Voltage is good on both legs 121v ,I got another unit up and running now thanks to Van I pulled the blower motor and the thrust washer was gummed up and wore out, cleaned the coils and oiled the motor bought new washers at RV place and was surprised they had the washers for 3 bucks ea its running on a steady 13 amps this morning but it is cool here.The last one is going to be replaced it is low on Freon from a long screw rubbing a hole in a line lol you can tell some service tech has been in there on the unit changing the condensate pump  1/2 the screws were missing and taped up wires.John Coleman told these were the roughneck design with thicker tubing,mounts and coils

Sounds like them heat waves keeps ones on thier toes with A/C maintenance. That thrust washer issue you mentioned is a good find as it was eating 10A dragging the armature' s spin!
Florida has finally hit the mid to high 90s with similar humidity. Aug. is commonly our hottest month. We're enjoying the new ponderosa central HVAC upgrade & are noticing decrease in electric & cooler quicker cooling cycle. Stay cool...

Hey Cliff, throw Chris up there an have him patch the lil' hole up. A son in law has to be good for at least some things lol!

[chessie4905]

I patched a hole in condenser a few years ago with an aluminum. solder stick with a propane torch. Wipe area clean and rub stick into tubing while applying torch. It worked fine. It is the stuff the vendors show attaching soda cans together. Ive always been skeptical of them, but it worked fine. Available at Harbor Freight also, but not wbere I saw the demonstation.

Cliff,

Not trying to be an a$$. Do you have a clamp on AC amp meter? First diagnosis, is to find the wiring for the compressor and measure the amps during startup and run conditions. Without that info, it's guess.

One thing that will cause high amperage on the compressor is if the outside fan is not running. Without a fan removing heat from the high side, the compressor is under tremendous load, i.e. high amperage.

Richard I do have a clamp on meter and the outside fan is running and spins easy.the one with the leak is the only unit not working now, the compressor will not start now

Great !

Sorry I was late to help, internet is not very good in the middle of nowhere Montana.
