Ok here is one for the books...
I traced my problem to starter solenoid. I ordered one from dealer. I recieved and it had a cracked plastic housing. So, I mess with my old one and see if I can remove plastice housing. Let me say you can't (well you probaby could but it would be hard) and I broke an internal wire messing with it.
I get the dealer to take the new one back and replace it at no charge. I then put the old one back on. This was so wires were tucked up neatly and I could still use tractor (big hills are great).
Anyway, once all buttoned up, I jumped in and decided to try and start it. I don't want to have to get the truck and have the wife pull me and tractor to the "hill". Well to my astonishment it started right up.
Long story short, new solenoid broke, old one broke (remember broken wire from above). New one sent off to dealer, old one re-installed and it works. New one on the way, still needed (that darn broken wire again).
So, once this is done,
Zetor will start fine. Then its time to replace the lift pump.
End of not starting story.
