JDcrawlers Messageboard

Thanks for all the feedback on the 12V problem.I did have it wired correctly with the resistor in the right location. The problem was the machine was backfiring and acting like a possible wiring problem I might have created when I rewired . Eventually,fter a long process of elimination,I located the...

I have installed an alternator (1-wire) on a JD 420C. The tractor is wired for Neg grnd.The 12 V coil is new and requires an external resistor.My question is ,does the resistor go in line between the coil and distributor or is it okay to install inalternator to battery line?

chains had just been installed prior to photo,the tracks have been relaxed to proper dimensions .Good pick up.

I just experience the same problem on my 430. Ultimately, I took the machine apart and sure enough ,clutch plate stuck to the flywheel. I dug a little into my memory bank and remembered that is why it's a good idea if leaving unused for any extended period of time to put a block of wood against the ...

you might try putting a battery trickler on the 6 volt and let it recharge to full capacity for a couple two or three days. Once it is fully recharged you shouldn't have a problem. I run all 6 volts on four different crawlers and have found this to be a problem if only running for a short time in re...
