GT20 Rewire

Last weekend, I went out to start my tractor and nothing, not even a click. Check the battery and it's fully charged. That tells me it's the safety circuit again. I knew I would have problems with this tractor from the day I bought it since you could tell the previous owner had modified the wiring already, so I did a complete rewire. Added some relays so I don't have to use the old pull switches if I don't want to and simplified things. It works great now, and I even got the lights to work that didn't before. From top to bottom the relays are Kill Switch, Lights, Front PTO, Rear PTO. I have room for more if I ever find a cab and want more lights on a different switch or something like that.

The reason it didn't start before the rewire was because the rear PTO switch had fallen apart. I took it out, found the pieces, put it back together and peened the sides back in. Works like new.

I am an Industrial Electrician by trade, so this stuff was actually really fun to me. The relays aren't necessary, you can do a complete rewire without them, but I like having them. Plus they are able to be mechanically turned on by hand, so if something is wrong they actually help with troubleshooting.

Re: GT20 Rewire

A tiny bit of overkill, but I like it!

I am an industrial process control designer/installer for the asphalt/aggregate industry, and love to apply my weird skills to odd ball projects. I have a cyclonic air filter system for my home wood working that is run by a Koyo DL06 PLC pulled from a job site. TOTAL overkill for such a simple job...

Re: GT20 Rewire

I am not getting out the ladder logic or anything, but a few relays to centralize power distribution never hurt. This is my second time rewiring one of these, but the first one was an old S14-H with points and no hour meter or rear PTO, so it was really simple. I really like the look of the relays too.

Re: GT20 Rewire

I have had more problems with ignition switches than anything else. Would think Ariens could actually make a replacement that worked for what they want for them. The last lost power to the start circuit on the second start with no return on electrical parts after take out of the bag. Can not discuss the work around for that one.

Yeah, I didn't go into any detail because of the forum rules, and I did all of this extra relay addition because Ariens wants way too much for new PTO switches and I have seen a lot of guys have issues with replacing them with anything else, so I went this route knowing I could always replace the switches later because I have relays now.
