    4020 24v questions (pt 2)

    Hey guys- I asked a few questions about the 24v system a while ago and learned a few things, but I have come up with a few more questions and hopefully you can help. It was suggested I put a battery disconnect on, which would help with battery life: 1) Does this help only if there is a drain...

    How to get 12V power from 24V system?

    Looking at those 24v to 12v converters like hemmjo posted.. I see they have 24v input and 12v output screws.. I'm assuming my input wires would be just like the starter? Negative from LH battery and positive from RH battery to the converter? And then just hook my accessory up to the 12v...

    How to get 12V power from 24V system?

    Sounds good. Maybe my LH battery crapping out is purely coincidental..

    How to get 12V power from 24V system?

    If I do the above test and there is continuity and I can't use the RH battery, I'm still ok to use the LH battery?

    How to get 12V power from 24V system?

    It seems to me like its small, but I'm not really sure how to test it? All it runs is a little solenoid that switches a valve from side to side.

    How to get 12V power from 24V system?

    The way I have been doing it for years is how I described in my original post.. I have a red wire and a black wire coming out of the box (which is bolted to the fender). The red wire is connected to the + of the left battery, and the black wire is connected to the - of the left battery. The...

    How to get 12V power from 24V system?

    Tractor is a JD 4020 with the 24V system, and I need to get power to my planter marker control box. The easy answer is to run a + wire to the + terminal on one battery and a - wire to the - terminal on the same battery, but that pulls a load from the one battery, and I have read that those...

    JD 4020 24v Questions

    That's awesome. The fuel gauge hasn't worked for a little while, so that's cool that its likely an easy fix. And I'll have the batteries load tested sometime!

    JD 4020 24v Questions

    Pulled the floor plate off this evening and see where the ground wire is bolted to the chassis, but its definitely not connected to the battery. There is a half of a slo-blo fuse holder, but the other half and wire (to the battery) is missing. I will definitely fix it tomorrow, but is that...

    JD 4020 24v Questions

    77771, so a 1964. I'll have to look under the foot plate, but I'm 99% sure the batteries are connected with the crossover cable. I haven't used the planter at all since last spring. Good to know that I might want to get power to that box some other way. I didnt figure it would matter much...

    JD 4020 24v Questions

    Just looked when I was home and didn't see anything connected to the + terminal except a wire I have attached there for my planter marker control box. I'll look again this evening now that I know for sure what to look for.. and I'll take the floor plate and see if there is anything under there?

    JD 4020 24v Questions

    May be a stupid question, but where is the small ground wire? I don't remember seeing one anywhere. Is it on the starter, or somewhere on one of the batteries?

    JD 4020 24v Questions

    Thanks for the info guys. The batteries are not real old, I think 2-3 years. I'd love to convert it to 12v, but its actually not my tractor and only gets used for food plots and some random brush mowing, but probably 20 or so hours a year, so hardly worth the expense unless actually...
