125 Wiring

I picked up a 125 off my brother that had been sitting for years. Didn't take much to get it running. It needs a battery which I picked up. The wiring is pretty brittle. I have the wiring diagram. It doesn't look like the wiring was hacked much if at all. In the diagram it shows the red wire going from the solenoid to the one side of the ampmeter. My wire goes right from the battery. There is a wire behind the dash unconnected. It is part of the harness and the end appears red and has an eyelet on it. Up at the regulator there is what appears to be a red wire unconnected with a spade on it. I put an ohm meter on it and the wire behind the dash. No connection. I have found the eleectric lift wire. So I ruled that out. The diagram doesn't seem to show this unknow wire behind the dash and up at the regulator. They might be connected but damaged somewhere in the harness. There are no lights on this 125. The grille is empty.

The negative battery wire to the generator seems small in gauge size. Also the same for the positive off the solenoid to the generator. I bought needs 6 gauge with end for this. If the 125 pans out I might consider rewiring it or buying a harness.

By the way the serial number is 219800. From a chart I saw I think this makes it a later '67. Maybe someone can confirm.

I have been looking at the 125 owner manual which has a wiring digram in it. There is a wire labeled #1 up by the regulator and dash. It is listed as a headlight feed. The wire I found could be that wire used if there were headlights. I'm missing the grille screen and headlight panel. There is no headlight switch were it would be so I assume the wire was just part of the harness should lights ever be added.

It could be, hard to say without seeing it. You say the wiring harness is pretty brittle, which is common for the series, I would replace the wiring harness with a new one, and solve some problems. There are some good aftermarket harness' available, one that comes to mind is from Mike Lamar, rustypete@integrity.com , and it has all the terminals labeled as to where they go. They are made just like the originals were as to wire color, terminal ends and wire braid. I think one for your 125 is $65 but you need to check with him to be sure.

I second this recommendation. I ordered a wiring harness from Mike Lamar for my 1200 Cub Cadet. Very good quality, sent ASAP too. I removed one wire at a time and then replaced it with the corresponding wire from Mike Lamar. I've had zero problems with my new wiring. Even my neighbors comment on how quickly my 1200 fires up once I hit the key switch. :{_}: :{_}: :{_}:

I got a harness from Mike. Correct. Very fast ship. each wire is marked and a diagram is included. I ordered a new IGN switch at the same time. I have the harness in place and things are working much better.

I would like to find a headlight insert next.
