JD 1050 starting issue

egal680 · Feb 27, 2011

I have always had a starter issue with my 1050 since I bought it 4 years ago and I have been jumping the starter to get around it but want to fix it once and for all. Turning the key would sometimes start it and sometimes not ( it would just click ) . Battery was replaced - no difference. Rebuild starter - No difference. I have continuity from the back of the switch pole C to the low voltage terminal on the starter. And the resistance drops to .2 ohms between the C and B ( starter ) poles when I turn the key to START position . but I just get one click when I turn the key . But - if I jump the back of the switch between the C and B poles - the starter jumps to life. So this leads me to suspect the switch even thought the resistance seems ok through it . I have also read posts about a low voltage kit AM107421 that might fix this problem . Can ignition switches read good resistance and then not function properly or will the fix kit work for this issue. Any pointer would be much appreciated.

:welcome:
Can't comment on the resistance question, but I'd get a new switch and go from there. But that is me.

Or add the jumper with a on/off switch to continue starting it that way.
I'll look forward to any answers that might help with the switch problem.

If JD is offering an aux relay to handle the current to the starter solenoid, that tells me that the ability of the switch, interlocks and wiring in the circuit is inadequate.

BTW, that is what I added to my Jinma, works like a charm.

Thanks, Ill take all the advise. Im going to reinstall the switch with a jumper for a little while ( just to make sure it really is repeatable ) and Ill look for the solenoid kit correct the circuit restrictions . Thanks

I would like to get a aux switch for my 1050

Are all 4 battery cables connections clean & tight?????? The battery ground cable end that attaches to tractor is often overlooked and the culprit. I also recommend adding a starter relay(solenoid) in between ign switch and starter solenoid.

I have a 1050 and am not experiencing any of these issues. Would you suggest that I get this part also? If so, what is the part number?

If it ain't broke don't fix it.

This will probably help more than any of the other ideas/suggestions. It SURE worked for the JD750 I used to have, which would often "just click" when I turned the key. Once I put the extra solenoid on it, it never failed to crank again.

I ordered the relay kit (AM107421) and received it today. The instructions are for Kawasaki. Does anyone have instructions for a JD 1050? I might be able to figure it out if I had a schematic, but don't have one. Any help would be greatly appreciated. Thanks. Ron
