Need electrical dragram on LA 145 John Deere riding mower

the coil wire is only a kill wire. it goes through the wiring harness through safety switches back to the ignition switch.

Something is loose causing a bad ground situation. Which will cause the wire to be burned. Locate the loose part and tighten it.

I’m happy to assist further over the phone at https://www.6ya.com/expert/christopher_722ea729aae6fd07

Hope this helps

Put the new belt on the back pulley. Place the other end of the belt onto the front pulley. By hand turn the front pulley and the belt will feed it self on.

If you can't find a wiring diagram, no problem. Follow the wiring to where it was ripped out. If it's your lights it's usually a black (ground) and a brown or brown with stripe for the lights.
Another way would be to just match the wires on both sides where they were ripped out. Example: RED TO RED, BLACK TO BLACK, etc. Make sure any wire with a stripe matches.

Here is a link with diagram and routing configuration, I hope this helps.

Sorry, a new battery is in the works.

Check your battery connections. Pull spark plug. A lot time the cyl. will with fuel.

This is the instructions for a L118 you may be able to find the 145 at the same site

Hiand welcome to FixYa, I am Kelly

This is the deck routing diagram:

There are 3 models of the LA145. Hopefully this is the correct diagram. The deck belt routing appears to be the same on all 3 models.

Thanks for choosing FixYa,
