The isolator switches on the batteries appeared to work in preventing the draw - as I had 12.5 volts prior to starting the tractor - and was enough to crank er over.
I also checked the current via positive terminal post - to positive cable with the tractor off. Put meter on battery's with tractor running - shows it's charging - 14.2v's. Interestingly - I started the tractor up and ran the idle up a little - and checked that broken white wire behind the switch for voltage - ad. The rest of the wires were dead with the key off (grn, dbl black, broken white). I have a grey wire that is dim hot with my test light - meter showed 2v's. Checked my wires for voltage with the key off- The blue, and brown are hot 12v's. The white wire spade was broken off from behind the switch.
#24 VOLT ALTERNATOR FOR JOHN DEERE 4020 INSTALL#
*I purchased a new switch from JD today - and will install and report back.ĭiscovered a few things when I came home and took t he old switch apart. (Start every 3-4 days to fill a hayfeeder) Is this telling anybody anything? I dont have a clue where to go next.but getting tired of having to boost every time I need to start the tractor. (one is quite a bit dimmer than the others) Went up to the key - all spades on back side are used. To my understanding - with the key off.my white wire should be dead. Unhooked the red/white wire clip that goes into the alternator - checked with test light.red = light, and white = dim light. Both batteries showing 12-13 volts after a charge. Tractor sits for one day.and it wont start without boosting. Hooked the batteries up parrallel (Both pos to starter - both negs to tractor frame) Switched her over didnt seem to have any problems. Seemed to help for awhile - but not long and was back to not starting if sat for more than a few days.Īfter many suggestions to switch the tractor over to 12v- I bit the bullet and bought the kit. At the time - was a 24v system.ġst thing I did was replace the battery's - 2 brand new JD 12v's. I can switch over the 24v system to a 12v system between 400 and 800 for all. This past summer - if the tractor sat for more than 2-3 wouldnt start. John Deere Alternator Wiring DiagramFor example, the alternator symbol is.
