What makes you think it is bad? What kind of issue are you having with the unit?

 

There was a bad terminal I need to replace. The ohm reading just seems low!

 

How do you replace a Bad Terminal on a sealed pump?

 

Thanks pecmsg. That makes me feel it’s ok. Waiting for kit.

 

Just wiring harness. The ohms just seemed low. But your link helped. Thanks

 

If the terminal is burnt you will need a repair kit with screw down connectors................

and even those are generally temporary!

 

I did state generally.
If the terminals are burnt/ discolored then it’s going to fail. How long depends.

 

I have always been told by my trained as long as c-s and c-r equals the s-r ohms then the windings in the compressor are good. It's when that number doesn't add up or you get infitnite resistance (unless it's on internal overload) or if you got short to ground.

I'm going to be following this post just for my own knowledge.

Back to the original poster was wondering I'm now also curious if the level of resistance matters or as long as the numbers add up your okay?

Ok, I got the compressor going. Had to tap it a few times. Don’t know if that really helped. But in been good for a week now. It’s 14 yrs old and supplies a hydraulic elevator machine room. Thanks

 

Did you check the operation, SH, SC?

 

Can the hole get plugged and allow the Accumulator to hold the oil? Yes but highly unlikely, Extremely long shot at best!
