Hi guys i love this site superb mature super guys anyway i have a sears 3 h.p air compressor that wont start under load? you can uncouple the belt and it runs? The start switch is working checked it with a amprobe and the start capacitor has been changed.i disassembled the motor cleaned and checked the bearings? this one has me stuck?? the motor has no data plate which is illegal i thought the tank has 3 h.p. but it has a 16 gauge cord.p s when it loads down it emits a high pich sqeel? thanks in advance?
thanks i have tried bigger cord ,uncouple 2 lines from compressor to tank i am not sure where the unloader is? How can sears advertise a 3 h.p motor that only pulls a few amps and has a #i6 cord.It must me the rating at the compressor end?i can rotate the compressor by hand.It is a used unit and looks to be a few years old/ thanks guys i am gonna try again .
