One more AC 720 Wiring Question....

Recommended Posts

mj
Came up with one more…I’m thinking this one I should be able to figure out but as you can tell my strong suit surely isn’t wiring! On page 26 in the parts breakdown for the rear pto & rear pto clutch there are two parts listed, the jumper wire (#2028808), and also a switch (#2028809). The switch part # is the same that is listed in the instrument panel breakdown, so I’m assuming that is just the on/off switch for the rear clutch that goes on the instrument panel?... but can anyone tell me where the jumper wire goes? The only jumper wires that are listed in the parts manual electrical diagram are for the optional hour meter. Any idea’s for me on that one? In my new wiring harness diagram it lists the jumper wire but it is listed like this: (Clutch?) Jumper lead? Doesn't say for sure what it is or where it goes....Thanks much in advance…..

Not all tractors had the rear pto. Since it was an option at one time if you added it you would have to add the dash switch and the jumper would be for the start circut. The start circut loop goes through both pto switchs and the neutral hydro switch you asked about in the other post. The switches are doubled up meaning 2 switches in one. One side energizes the clutch, the other is the interlock for the starter. On the starter side of the switch you must remove the plug for the starter circut, insert a small flat screwdriver in the locking tab, remove ne wire and replace it with the jumper wire. Take the wire you just removed and replace it into the new plug end and place both plugs back on both pto switches. This should return the starter interlock to working order. Thats the factory way. These starters drew a lot of load and gave the safty circuts a little trouble. I would suggest adding an aux. solinoid to help. I won't go into details here now but you can make your own or club member Al Eden offers a kit to do this with instructions. Do a search on powermax starters and it should come up. That will discuss it in more detail and talk about what kinds of problems they have and why they need this modification.

      Good morning peeps! I’m always searching for helpful information with my AC collection. Hope to find out new information and pass on my own experience in restoration. Here are some pics of my babies. I’m still looking for front rims for the 410 so yesterday I put the 310 wheels on took it for a drive. Working pretty good but still needs some carb work. Gotta get the 310 running next. Have a great day!😁
