Im having the Same problem. i accidently pulled the clutch safety button with the clutch pedal, so i had to disconnect the wires to get it in the right spot, and when i pluged the wires back in now it wont start, same situation as you. Battery terminals are tight, head lights are bright, just wont turn over.

 

have u tested the clutch safety switch? make sure its sending signal when peddle is pushed down. cant find the volts spec and gotta go unload crab from the boat so ill look later. later. lol.

 

Well i found my problem.. when i replaced the clutch, i was pumping the clutch pedal..i guess i pushed to hard and to fast and broke the clutch button when the pedal is pushed down..so i took a piece of wire and completed the circuit, and what ya know it started right up..lol later i cut the connector off and hot wired the two wire together and put a wire nut on them with some tape..now i dont need to push the clutch pedal to start the car..lol i still push the clutch out of habit tho.

 

u better fix that switch or u will be starting in gear and running into or over something. its real easy to forget.

 

i still haven't fixed my problem, i haven't had time and the weather has been crappy. Maybe I can get mine fixed sat. I am going into withdrawals...
