Title: Pin identification on Ball style compressor for a 3 in 1 hookup? Post by: SIGNGUY on August 29, 2017, 08:55:34 am I am trying to wire up a ball style compressor with a 3 in 1 starter..
I am not sure what pins are what on that style. I found an older diagram from Johnnie G that shows the common on top, Start on Lower left and Run on lower right. however the color of cables used in this diagram show reversed from what the 3 in 1 on show? this was on a pancake style compressor. I need info on the Large ball type compressor in a 81. Right now I have it hooked up as show on Package of 3 in 1 , White to start, black to Common and Red to Run... but it trips circuit. please help.

Post by: johnieG on August 29, 2017, 09:29:36 pm I assume you mean it trips the circuit breaker...with the power off, disconnect the 3-in-1 from the compressor & ohm each pin to the case of the compressor ( sandpaper a small spot on the case to get a good connection to metal) I think you will find it has a shorted winding to ground/chassis, in which case it's toast.

Here's an old post where I explain how to find what the terminals are with a meter on a single phase compressor. I agree with Johnnie, it sounds like it is grounded and definitely would be toast.

thanks for the tip. Title: Re: Pin identification on Ball style compressor for a 3 in 1 hookup?

Is it the original compressor? Title: Re: Pin identification on Ball style compressor for a 3 in 1 hookup? Post by: johnieG on September 02, 2017, 06:02:25 pm Is it the original compressor? I believed he said it was original in a V81, probably a Blisfield hermetic, quote " a large ball compressor" certainly a picture would help in any case. Is be surprised if it wasnt shorted to ground from the symptoms |
