Motor capacitor burnt out on kindlet ?

[peatff]

don't mean to hijack the thread but I bought a second hand electric cement mixer that needed re-wired, the wires were off the capacitor so I re attached them and got the mixer running again, only in reverse:blushing: could this be because I maybe wire the capacitor wrongly?

 

AC start capacitors should not be polarity sensitive, were the wires off because someone had swapped the motor ? I got a pressure washer out of the skip at the bike shop and fitted a new capacitor and ran it for another 3 years till the pump packed up.

No it was the original motor but some genius took all the wires out of the starter switch and couldn't figure out how to put them back. Anyway I took the motor, switch, and wiring to a guy who re wired it, all I had to do was put everything else back together, maybe he wired it wrongly?

Sounds like the connections were reversed on one of the windings.

thanks Cornish wood burner, is it a big job to fix?

Normally just reversing two links and possibly a supply connection. What needs to happen is to reverse the supply to either the start or run winding, not both. Considering the motors history, I would take it to the guy who wired it for you.

much appreciated, will do.
