John Deere LT 155 wont start

So I have a 1998 John Deere LT 155 and it won't start anymore. My dad and modified it so most of the wiring that would be on the key switch is on auxiliary switchs. I think my problem is that the wire that would ground out the magneto is just constantly grounding it out. Anyone got any advice?

those re-wiring jobs seem to always lead to problems.  I would start with the ground wire, check if it has continuity and if it loses continuity to the frame when the key is on.  If that is the problem, either a new wire or following the old one and finding the short is the answer.  If that is not the answer, start with the basics.  Do you have gas, spark and compression.  If so, it is probably a timing issue.

Assuming it cranks and has fuel then no spark is the issue.  The mag being grounded would be the first thing I'd check.  Remove the ground wire at the engine wiring harness plug to see if it'll run.  

A complete description of the problem would help pinpoint the problem.

So I put a wire to power and it runs now. What is normaly off and start on the key switch are run and run is off. I'm not going to touch it. I'm just happy it runs 😂
