Capacitor swap
by: Bill

Are you 100% sure that the capacitor you "swapped" is the correct one for the motor?

Hi bill thanks for the speedy reply,there isn't any additional equipment drawing power so I've swapped the capacitor with one I had off a spare bambi compressor and still have the same problem,so I also changed the start relay and still no result,what I did forget to mention is that I've got one pump off the bb50d and one pump off a bb24v running on my bb50d compressor,the bb24 is the one that gets hot and the bb50d pump is the one that shuts off early,
Kind regards Geoff

Bambi compressor motors
by: Bill

Is there anything new in the power supply to the compressor?

Are there now other items on the same power feed to the compressor that may be drawing power away from the compressor motors?

If not, then see the page on this site about how to check motor capacitors. They may be the issue.

Let us know please.
