theres power on both sides of the field @ the brushes , how would i test the armature? maybe the guy i got it fron didnt replace it, the brushes i can see are brand new

Hey,
When you say power do you mean live voltage or ohm reading? If you have an ohm reading on the brush's from both sides of the armature it is probably ok..you can just check just the commutator bars also..you should have a reading all the way around.
I would start from scratch on this one and check the cord for live voltage..[sometimes you will get a ohm reading but live voltage will break down and not go thu..in other words.if you only have a few strands of wire an ohm will read and say it is ok but the voltage wont make it thru only a few strands of wire in your cord..not enough of good wire..] This is also true with other components..a switch checks ok with an ohm but when you check it with live voltage it breaks down in the switch and wont come out the other side..
Anyhoo, if everything is checking out with your tool it should be running..dang it!
