cub cadet 72

the new one has three on the right side they are field, battery and lights and the one for gen is on the left side

This is a picture of the old one I took when I started restoring it and this is the one that I found on Amazon that is on it now

The main issue I see is, you have all 4 terminals on your old one hooked up and the L terminal is for lights which you do not have.

 

[Will bradshaw]

the old one also had ground and no tab for lights since the tractor did not come with them the new one does not have a tab for ground

 

[Will bradshaw]

i ended up having to ground it elsewhere and i did put lights on it

 

[bwstevens]

So the lights are fed from the L terminal ?

 

[Will bradshaw]

they are not as of yet i was trying to get the ignition and charging system straight before i wired them up

Newer V/R's are case grounded and need no separate ground.

 

[digger]

Yes, other wise that terminal is not used.

yes but there was a ground wire in the harness that went to the original regulator and the engine wouldnt crank over unless it was grounded

Check your wiring,

ive been over that diagram more times than i can count lol and there is a ground wire shown in that diagram going from the battery to the regulator

 

[bwstevens]

There should be a bigger ground wire going straight to a bolt on the starter itself

 

[Will bradshaw]

yes there is

 

[bwstevens]

then the starter should crank with the regulator ground unhooked.

so the ground up by the regulator is just to ground the regulator itself?

 

[bwstevens]

Yes so that the field part of the regulator works accurately . Not that any of the ones I have do work all the time on my big tractors. I have 7 garden tractors that use a mechanical regulator and 22 farm tractors that do also.

so does that mean I need to find a regulator with a ground on it and would that be part of my other problems?

 

[bwstevens]

Regulators ground through the base as Digger said last night so put the ground wire on one of the bolts that mount it. As for the problems it sounded like your starter didn't crank without the regulator ground connected ?

 

[Will bradshaw]

I thought that was the case but I double checked that after I got off work a little while ago and it did crank without the regulator ground connected. Did some digging last night and found a kit containing the points, condenser and a new coil all made in America supposedly so I’m waiting for that to come in now

 

[bwstevens]

I know what you are experiencing as I'm waiting for a new ignition switch from CC Specialties.
