I am doing some finishing touches on my 620 that I am working on and I can't get the rear lights to work at all. I am positive I am getting power to the lights and I am pretty sure it is an issue with the ground. I was reading old posts about people that ran wires down to the frame but I am not sure how to go about doing that. Suggestions??

we have used the tab on the back center of the frame where i believe the 3rd ling is suppose to hook. just put an eyelet on a wire on run it straight
to the battery ground.
if you have a 3 point or want a more concealed wire i have run an extra wire up the armrest with the 2 power wires, i actually drilled a hole just big
enough for the wire in the back of the light housing and hooked it right to the light socket.

I FINALLY decided to correct a design error on my tractor, where they used the frame and all the joints to return the ground current back down to the battery. I ran a separate green ground wire from each light socket down to the battery post. Voila, everything works, lights are bright. You will be correcting a design error. Go to it.

Why don't you run double wires to the lights and place them in a neat black shield and stop all your problems. I would use a ground block somewhere under the sheet metal to prevent moisture. I always gounded battery to one of the bolts for seat and battery platform.

Actually there's a lot of individual updates you can do to these tractors. From the factory these were run of the mill setups and weren't really supposed to be around 60 years. Another weak point is the grounding of the generator. All these problems plus all the excess vibration is why there are so many regulator and generator problems. Actually I think the regulator "should" never have been placed on top of the generator. Just think of how you're buying so many problems. Should have been placed under the dash board.

Machinery man I could never figure out why Deere put the regulator so close to that red hot exhaust pipe. When we used our two bangers hard it seemed like regulators didn't last long. Now that we just putz around with them the regulators last for years.
No. Ground (really chassis) needs to connect to the bulb socket by soldering (if you run the wire inside the light's body) or it needs to
connect to the exterior of the light's body with a machine screw. I've done it both ways. Either way you must drill a small hole in the
light's body that allows the wire to pass through or a machine screw to hold the ground wire termianl.

Actually, all you really need is a wire between the upper seat frame and the battery box. You just need to ground the seat frame to make the light work (assuming the light housing is making good contact with the seat frame). Especially if you've painted everything where the seat frame slides on the battery box.

I did the same thing. Drilled a hole and attached a wire to the seat frame under the seat then attached to the battery terminal. It works great.
