2003 TC30 Won't Start

[Harry in Ky]

The starter has a ground wire? Can you elaborate a little on that?

Good day folks,

Blue wouldn't start for me today. I call her Blue on account of her color...lol!

Hope you don't mind me running this by you before I go down the part buying trail. I suspect it is the ignition switch but at $300 per unit want some more assurances before ordering. Am I missing anything in your opinion?

Thanks in advance for your help and interest!

This is what I've done.

1) Tested continuity between starter engage pin on switch with starter connector - Good.
2) Engaged glow plug. Illustrated good on dash.
3) Positioned key in run position. Illustrated good on dash.
4) tested voltage in run position, good. On glow plug position, good. When I move the key to start position, I LOSE VOLTAGE.
5) the seat safety switch is disconnected and shorted out to make a closed circuit. Been this way for years.

Also it appears this switch part number is dependent on the PIN of the tractor. I have looked on the tractor and online for the PIN but can't find it. If anyone knows of this please pass it along.

Thanks again and cheers, Greg.

I had the same problem with my 2000 tc29d. It turned out to be that the ignition switch was loose and instead of going all the way to the start position it stopped short.

Looks like I spoke too soon. Blue is down again despite it starting 10's since I cleaned and tightened the + battery wire to the solenoid.

It would appear that I am not getting 12v to engage the solenoid. The solenoid works as it closed when I applied 12v to the tab.

I traced the wire back to a relay that is close to the fuse panel. Checked it for continuity and it passed.

I am getting to the end of my limited skills here. Any thoughts? Are those relays prone to failure? It's cheap and wouldn't mind swapping it out for ***** and grins. Could it be a safety switch? I disabled the seat switch years ago and it appears sound.

By the way for anyone doing this repair the hidden bolt on the starter is a nut and bolt unlike the visible fastener. You have to take the front and side panel off to get a wrench off of it. I am embarrassed to say how long I spent trying to remove it thinking it was stripped, meanwhile it was simply spinning.

Thanks in advance for any additional feedback.... cheers

Thanks for this .... a lot cheaper than OEM.... I almost dropped when quoted. cheers

Meant to say battery wire.... I was burnt out.... good catch.... cheers.

Maybe I missed it in your description- does the motor turn over when you try to start it or nothing happens?

Sorry missed this.... no nothing happens. As it turns out not getting 12v to the solenoid activate terminal. traced the wire to a relay and checked good for continuity. Cheers,
