Anybody got a clue on this one?
The starter on my Yamaha Moto 4 250 started groaning when I try to start it. Eventually it would spin over and start. The other night I figured I'd better do something about it. I had what looked like an identical starter off a Moto 4 200. I put that one on and it wouldn't work at all. I hooked it to a battery with the jumper cables,still nothing. I took the original apart and it had a lot of oil in it. I cleaned it all up,put it back on and it started right up. I rode it,shut it off and it wouldn't start again. I took the other one apart,it had oil in it too. I cleaned that one up,wouldn't work. I ordered a new one but it's not here yet.
I had some time on my hands today,so I took both of them apart,cleaned everything up,took the best parts from the two and made one. I hooked that one to a battery with the jumper cables,negative ground,it spun. I put it back on and it was spinning the wrong way. I took it off,hooked it back up to the jumper cables,positive ground and it spun the right way.
I tried every possible combination of armature and field housing,got the same results every time. The plastic was partially melted in one end cap,so that was the only thing I couldn't try swapping out. No matter what I did,it spins backwards when I hook negative ground or put it back on the machine. I haven't had any other wires unhooked.
Last time I put it back on,I hooked the jumper cables right to the starter,positive ground and it started. Shut it off,turn the key right back on,push the starter button,it spins backwards. I even tried switching the cables on the battery in the machine and it blew a fuse.
I'm stumped. If the new starter turns backwards when it gets here,I'm not gonna be a happy camper.

Today's Featured Article - Grain Threshing in the Early 40's - by Jerry D. Coleman. How many of you can sit there and say that you have plowed with a mule? Well I would say not many, but maybe a few. This story is about the day my Grandfather Brown (true name) decided along with my parents to purchase a new Ford tractor. It wasn't really new except to us. The year was about 1967 and my father found a good used Ford 601 tractor to use on the farm instead of "Bob", our old mule. Now my grandfather had had this mule since the mid 40's and he was getting some age on him. S
