electric spark

[wisconsin johnnie]

Every time I touch my neg cable end to the negitive battery post, it
sparks and trys to turn the engine over. Key is off tractor in neutral.
It a 12 volt system converted over about 6-8 years ago. All
sugestions are appreciated.

It would help if you told us the tractor you have since the 9N did not always have a true solenoid. If it is an 8N then you problem is either the starter button stuck in the down position or the solenoid has welded it self closed. If you have a solenoid some times you can tap on it to free it up

It's an 8n, and I just replaced selinoid

You're solenoid is either stuck or wired wrong. Is it the 3 post or 4 post solenoid?

Stop guessing & do some diagnostics. Remove any wires on small terminal(s), leaving only the large terminals connected (one to battery & one to starter motor) and then reconnect battery.......what happens now?

Just because it is almost new does not say much these days. It should be a 3 wire type and if not then you have the wrong one and that can be the problem but if a 3 wire you may have in on back wards since there is a true battery side to some and a true starter side and if on back wards they can do funny things or you got a new bad China junk solenoid

Johnny........you do know the IGNITION key has 'nuttin' to do with the starter motor, don't you??? The ONLY thing that messes with yer starter motor it the BIG thumb switch by yer tranny shifter.

When you replaced yer starter motor mounted 3-terminal solenoid, remember to mount it so the little MIDDLE terminal faces the tranny and is hard to gitt-too. Then connect the little middle terminal thru the bottom of the dash panel to the BIG tranny push-button starter button.

Surprizingly enuff, 12V conversion has 'nuttin' to do with yer reported problem ...but... a reversed 3-terminal starter solenoid will cause the problems you are complaining about. .......respectfully, Dell

isconsin johnnie....don't pay ANY attention to the NOISE that you are getting in some/most responses here. I am amazed at what some put out here as knowledge/advice! Continually amazed! FACT: install the correct solenoid with the two big terminals reversed and the result is that it will do absolutely nothing/zero/notta!
It won't "act as your's is acting"!
It won't do "funny things"!

Disconnect the small wire at the solenoid and try to put the cable on the battery; does it turn the starter on now, or not? If it still does, the solenoid is stuck; if it does not, the little wire has a defect causing a ground to the tractor or the starter push-button is defective.

IF it is the correct solenoid, 3 terminal, for an 8n.. and if you have it wired correctly.. make sur ethat the small wire from the thumb switch is not chaffed and grounded to the frame. if it still wants to turn over hooking up that lil wire.. check the switch with an ohm meter to see if on the odd chance the switch istself is shorted.. perhaps at the small terminal at it's base.

What is a nuttin Switch?

 

[wisconsin johnnie]

I took your suggestions and tried to figure out where my problem lies.I switched my cables to the selonoid, touched the neg cable to the post, and nothing happened. No headlight, no nothing. So that told me I had not mounted my cables to the selonid incorectly. I then hooked everything up like normal and took off the wire from the started button to the selonid. touched the neg cabel to the post and it sparked, so I eliminated that as a problem source. I now wonder if I don't have a short somewhere in my wireing throughout the tractor. Any easy way to help diagnois whch wire it could be?

What are you talking about? Where did anyone say nuttin switch?

ou should have had one big solenoid terminal connected to starter motor. The other big solenoid terminal connected to a battery cable AND a big wire going through the ammeter. So, now what did you actually swap? From where to where? We need to address 3 wires here.

Mimos.........what do you think 'nuttin' means??? Its MY writing stylistic form for NOTHING.

I answered......"the IGNITION key has 'nuttin' to do with the starter motor" .......therefore....... the IGNITION key has NOTHING to do with the starter motor .......UNDERSTAND???? ........respectfully, Dell .........sheesh!!!

 

[Anonymous-0]

Oh, I understand now, But why do you use that type of writing?, It makes your answers hard to understand?

I am no expert and there are many on here but maybe I missed it have youtried disconnecting the starter switch? Just a thought.
