I have an older tractor about 15HP maybe a 1990 MTD. But the main thing is there are so many wires even with a new battery the tractor refuses to even make a clicking noise upon turning the key.
But having said that I wish to just get rid of those wires. And do a simple hot wire for now to see what is what.
I have watched some videos on hot wiring including a push button starter and kill switch toggle as a new modification to eliminate all those wires. I don't care about the lights working or not, just want the engine to turn over.
The thing that my tractor has that might be an issue is some sort of ground wire with a mini molex connector that plugs directly under the carb bowl. When the tractor did run when you unplugged this wire, the engine shut down.
These are some things I have noted that I need to account for:
1. The coil has the spark plug wire and a thin black wire( ground I am guessing )
2. If you look at the starter side of the engine,you see the hot lead ( from battery ) going to the starter, another red wire for going back to battery ( to charge it ) and then some other wires. The other wires concern me, not knowing what they do.
But if I do a simple a very simple connection where I connect say a black 12 gauge 15 amp wire to the new battery (- side ) and on to ground, and then a brand new red 12 gauge wire 15 amp wire (+ side ) to battery going to the starter with all the other wires removed except the spark plug wire, will the starter engage? I don't care about back feeding current right now to re-charge the battery, just whatever the minimum configuration is needed to figure what the problem is. In 2014 I had to take the kill switch out which sits under the seat because this was a problem then. After that it worked fine for a while. But it seems there are so many safety features, gauges, lights etc which I don't need is messing up all the electrical to the point where nothing works.
So will this work?
