TORO Proline

I just bought a used TORO Proline 32 from a good freind of mine but I am having problems with the clutch. He put a new clutch on it about 6 months ago due to the blade not ingaging. Now that I have the mower I can mow for about 10 min and the relay will burn the contacts up. The first time this happened the relay would not allow the clutch to engage and I replaced the relay. With the new relay in I was mowing for about 10 min the relay stick again but this time the clutch will Not disengage. I was woundering if maybe the clutch good be deffective but at $400 I would like to hear some other advise first. By the way I dont know if it matters or not but the relays that have been used are from a Auto Parts store and not the TORO dealer.

Thanks for any help
Mark

Was the clutch bought from a Toro dealer?
Clutches are directional. If the clutch plate is pushing the belt instead of pulling it,
The clutch straps wil bend and lock it up. Stay on without 12 volts.

First I would replace the terminal in the relay jack. Dirt = high resistance = heat. Enough to easily melt things. Second check the clutch coil resistance and for a path to ground. Both good and bad. FYI relays aren't close to being all the same.

I checked the resistance on the clutch its self it is very low just under 2 ohms. And I have good grounds and no shorts to the frame. I have not checked resistance for the harness its self that will be something I do. I will also check the terminal ends and clean them all


Thanks for helping out

I have bypassed the relay and the module and put in a fuse inplace of the relay incase it shorts out or gets hot. I made the handel switch the permanent on off switch and mowed my entire lawn about 30 min worth and it worked fine. I don't like it like this as its not the way its mint to work. I think I will leave it like this until I can replace this old mower with a new one in a few months. If any body as any suggestions on what's wrong with it let me know as I would like to put it back the right way

It could be as simple as a dirty connector. Really. I'm not just making it up.

I cleaned all the connectors with contact cleaner and my air compressor the connection at the clutch pig tale was very dirty but my problem was still there, the only wire getting hot is the power wire from the relay to the clutch I am thinking maybe this aftermarket clutch is the problem. I tightened all the connections that felt loose also.

Is there a way to test the module and also does anybody know what the voltage is suppose to be going to the relay or the clutch.
