140 12v conversion complete

Postby jdeere86 » Fri Mar 25, 2022 11:08 am

hey everyone

finally got some time to attack the 12v conversion again -- got her fired up nicely -- was beyond happy --couldn't have done it without this forum- thought you may like some photos -- included is the wiring diagram I used -- I didn't bother with the lights as I never use them -- was able to re use good mount of original wiring -- worked so why replace

got parts i needed for this conversion from yesterdays tractors including the mounting bracket

did end up having to get a slightly longer belt

as mentioned i removed the lights and light switch so now I have a hole in the dash -- anyone have any recommendations for cool/useful gauges to put there in place?

I wouldn't open up the switch hole to fit a gauge. You might want to put lights back on some day. But that is just me.

How about a charge indicator idiot light? You can probably get one that fits the switch hole.

Lights have other uses like it you have to take in on the road it helps a SMV be seen as well as the operator to see at night. I think you get some snow in western Mass. The 140 is a great snow plow and the lights are a big help.

I had a cigarette lighter on one the dash of one of my 140s. I did drill that out and put a USB charger and a voltmeter for a motorcycle/boat. It has a switch so it does not kill the battery. It is nice to have volt and current meters.

I hardly ever use the lights on my tractors, either but they look so much better with lights in place. If it were mine, I’d put them back on.

The USB port is pretty slick, I put one of them on my golf cart. I can’t think of a need for it on my tractors, though.

It was the only voltmeter I found that had a switch. I bought it for the switch not the USB ports. I wanted to wire it directly to the battery side of the push-button starter switch and not through the key.

Thats a great looking job. My 140 has a factory installed alternator, so I tried to duplicate the mount, when I converted my little A over.
I mow with this tractor, so I installed newer sealed beam head lights and even added an extra one to help with mowing after dark, and a tail light on the rear.

I was going to remove the Mag, and put in on a distributor, but in the last 10 years that I have owned the tractor I have not had any problems with the Mag, so I hate to change it.
The 12 volt is a nice upgrade for a user class tractor.
