Ignition Problem Ford 1710

After checking the other thread I found a very interesting photo of a starter / solenoid posted at

http://www.tractorbynet.com/forums/new-holland-owning-operating/208022-1710-starter-dead.html

Mine which WAS working (acquired used a couple years ago) seems to be wired wierd. I'm assuming the heavy red wire in the photo is positive to the battery. On mine the positive from the battery is on the same terminal as the heavy braided wire that enters the starter.

The picture makes sense, my layout does not.

I just started reading this post so I am not sure what all you have done except for the new battery and some tests. My question, have you taken the negative cable off from the battery and also from the tractor frame and replaced the cable with a new one? With all the things not working on your tractor it sounds like a major lack of ground connection.

This could be leading to your problem. Sounds like the starter cylinder solinoid has been by-passed on your tractor. I am not sure what all problems this might cause. We need for a tractor mechanic's opinion here, which I am not. :confused2: I am surprised it has been working that way for 2 years.

Hi Ray,

I will check the ground, but I am getting 12.6 volts at the end of the positive to the solenoid grounded to the center of the battery terminal so I have not pursued this too far. I get the same 12.6 when I ground to the frame directly.

The guy that owned the place that came with the tractor had some interesting ways of working around problems, shall we say, so nothing really surprises me other than this ever worked.

I will see if I get any more input, but my next plan is to wire it correctly and then see if it does anything.

Good morning,

I got your pm. The pic you're talking about is my 1700. I'm not 100% sure if the starter on your 1710 is identical to my 1700. if the previous owner took the red cable and directly connected to the braided wire causes the solenoid to be completely bypassed why, I don't know. I wonderd if the solenoid still works. by connecting it like that he always has the starter energized but why.. nobody does that. When the solenoid is made it ends up doing two things, first pushes the gear of the starter to mesh with flywheel and then internally connects the the red cable to braided cable to start turning of the starter. You can independently check the solenoid have, you jumped positive from battery to the solenoid terminal? what was the result?

I'm just reaching here.. is there any possibility he rigged it up that that the the starter gear constantly meshes with the flywheel?? although it is totally bizarre.:confused2: and if so how he turns the starter off? is he manually starts the tractor just by jumping the red cable to battery terminal bypassing the clutch safety?

can you manually turn the starter? do you have any pics?

JC,

Put the solenoid wires on properly, but still get no volts at the ignition. It looks on the wiring diagram that power to the key switch is through a red wire from the alternator and through a fusible link (also red) from the battery to the red wire from alternator. No voltage on the red wire at the ignition switch. Can anyone tell me what a fusible link looks like or have a photo?

Did yo read my post? the red cable is directly connected to the battery to alt. Switching is done at the solenoid. can you turn the starter manually? alt body is grounded, use the hot from the battery to the braided wire at the alt and see if starter turns.

Read it. Changing my name to dumbford1700. Its a 1700. Put it all back together (as in your picture) cleaned up battery posts and frame ground and getting low juice on the ignition now - weak horn, one weak light on the instrument panel. I have it on the charger (even though meter said 12.5 volts).

cool, You're making good headway. Just curious why anyone would rewire it as you explained I think you'll have it running once battery is fully charged. I hope your solenoid is not damaged.

I haven't given up. Had to take the charger off due to rain. Pulled starter and next step is to have it checked. I will replace the battery ground strap for good measure.

Sidenote, called the local Ford tractor place to see how much a starter was and the parts guy couldn't believe it had a new part listed at $1000. He is checking aftermarket. Looks like this will be bought over the internet, if I need one.

Also anybody have any experience with rebuilding these things? Is it cost effective?
