Electric clutch wiring

Ok the cross of the T is constant positive with key on, ( Didn't check off). The pto switch completes the ground. ( Cub Cadet 2500 series) not sure if that will help but I hope it does.

Yea I was surprised myself I figured the switch was power supply and the clutch may be grounded to frame or thru the engine as well . I did use a meter though and there's no ground in the wiring unless you pull the switch out. Again that's on a Cub Cadet though.

It's pretty common practice these days for anything automotive in nature to have a wiring harness for almost everything (including grounds). My F350 wiring schematic shows an incredible number of ground wires run all over the place. We can thank computerized systems for that.

You don't mention what tractor you're asking about, but with all Simplicity tractors that I've looked at wiring diagrams for, the switch supplies the +12v to the electric clutch.  Older tractors had the negative side of the clutch wired directly to ground or used the clutch case as ground (single lead coils).  The newer tractors had the negative side grounded through interlock switches or an interlock module. 

I'm not sure if the electric clutch coil cares which way the current  flows through the windings, but it's always better to wire it as the manufacturer prefers.

was originally a one wire system.

grounded thru case .

New clutch is two wire.

plus ground is diode  protected

So I ran power to clutch thru the top of T connector

and the ground thru the vertical part.

new switch disconnects both power and ground

      Hello glad I got on this site. I hope to upload a couple of photos of my Simplicity Broadmoor 
      Model 707 Tractor. I have replaced all the belts on it and installed a new ignition switch.
      Have a mower deck which was in poor shape , repaced a couple of bushings and welded the
      deck where there was some holes. The tractor and mower deck came from a friend and the 
      mower deck metal was getting pretty thin. Some new metal was put in it and we also undercoated the underside of the deck. This was done by my friend Greg Toulman.
      I have not put the mower deck on the tractor yet, waiting for Greg to come home and give me a hand. Can you please tell me if there is a manual for the mower deck and where I could get one.
      I would also like to get some moon wheel discs as well.
      I will try and down load some photos of the tractor when my wife shows me how to. 
      I really love driving this tractor and also how well it is made compare today's tractors, especially the flexible rear end and the rollers.
      Tell the next time 
      Paul
