hi I have got a john Deere 3130 the problem I have got is on my solenoid is when I connect the battery to the solenoid the starter will start to run although I have got the key in my hand and I have not gone in to the cab to start it I have tried many different solenoid and they all come with the same fault does anyone have any idea what it could be as I need to use my tractor but I cannot because of this anyone with help or suggestions would be appreciated or know of anyone who would I have also posted this on equipment as well forgot to say that the starter makes the sound when a 12v is added but will not crank the engine over  though as I would not have control over it so the battery's are disconnected until I can find the fault or get someone to look at it
many thanks john

ooh be careful, i saw a tv emergency programme about a farmer whose tractor started when he was on the ground and it ran him over.

It would appear that this is a solenoid problam, than you say you fitted ones,
were thy new. Is the solenoid on top of the starter?
check wires up to starter switch and also the switch.
For a short.    Could be a starter, when its not cranking over the engine.
Some input hope this helps

Hmm...


if the starter is cranking the engine then:-

My first guess would be that the problem is the starter 'keyswitch';
my second would be the wire that goes from the starter switch to the solenoid is shorted to another wire.


if the starter is spinning up but NOT cranking the engine (and it's happening with different solenoids):-


then my best guess would be that the solenoid was not fitted correctly:- there should be a rod sticking out of the solenoid at the opposite end to the electrical connections. The rod has a hole through it's end - this rod should be hooked over the end of a lever in the starter so it can pull the lever when the solenoid operates.


If the solenoid rod is not hooked over the lever, then when you fit the solenoid into place it will push the rod into the solenoid and close the contacts - making the motor run (but with the lever pushed forward the starter wont engage with the engine.


This is assuming your starter is constructed like the ones I've seen - so it's just a guess.
