Re: Help with wiring to solenoid
This thing has obviously been modified or converted and so no one can assume anything about the wiring, so as other's have said, the wiring/ compontents themselves can be causing the whole problem.
We need to know what kind of alternator you have and how it's wired, if nothing else, post some pictures.
there are different wiring schemes for solenoids.
Some have a "grounded base" where the "small terminal" feeds voltage IN to the solenoid, through the (magnetic) coil to ground
Some have an "insulated" base and here we can get into trouble, there's at least two different wiring schemes
some insulated base solenoids have the coil hooked to a small terminal AND one of the big battery terminals----you ground the small terminal through a one--wire switch to energize the solenoid
Some insulated base solenoids have TWO terminals, and therefore you must hook "juice" to both those terminals
HOWEVER on wrench in the works is the popular "Ford" solenoid used for years and years on Ford cars and trucks. It has TWO small terminals, but it is a GROUNDED BASE--one small terminal "needs" juice to start, and the other small terminal becomes hot when the solenoid is engaged. This small terminal feeds 12V OUT to the coil for a hot spark during cranking
The next wrench in the works is does this tractor have any safety switches? Seat/ clutch/ transmission/ etc?
Get a 12V test lamp, a digital meter (they're cheap now, 20 bucks here and there, parts stores, Sears, etc) and get yourself some good heavy alligator clips and make a couple of jumpers. You CAN buy them at Radio Sh## but they're not particularly good quality.
So determine why the solenoid won't crank FIRST
What did you do, what is this "second" starter button you hooked up?
