Starting problems

[Lagersolut 613]

My 2005 classic GT is driving me crazy  - acted like the solenoid was bad, replaced it, same problem - juice everywhere,  but not the starter when turned to start - seat switch- reverse shut off- both jump wired shut - neutral switch checked good for continuity - I have over 12 volts coming out of the start terminal on the ignition into the relays but nothing at the starter side solenoid ( this problem comes and goes - had to quit looking ... decided to start working again tonight ) I can hear the relays " clicking " when turned to start - . I'm no electrician by any stretch , do have a multimeter and can do the basics - right now I'm wondering what and where else to look - cross solenoid terminals - fires right up .

 

Any ideas where this circuit is open ( at times ) not starting ?

Here is a detailed wiring diagram. The starter circuit has it's own diagram making it easier to trace.

Thank you Gary , I was going off the full wiring diagram diagram in the owners manual making it very difficult to isolate the starter circuit it start mode ....that's the ticket

I had a bad PTO interlock switch on one that cause intermittent starts (with clicking)

 

It was on an older C series, but since that was the one safety switch you didnt mention, I thought it would be worth a look.

This newer model has a PTO lock-out too, I was having a hard time deciphering which terminals needed to be checked for continuity , the owners manual diagram is very confusing and the thing decided to start working again - I'm down to that or the parking switch- if they check good I don't know where else to go but the relays - it has 4, not going to be easy to find - the PDF file Gary posted has the circuits broke down in separate diagrams for " run " start "   " off " etc.

Doesn't take much dirt/ corrosion on one of these tractor terminals to cause a problem. I've even seen where the corrosion starts at a terminal and gets inside the wire insulation

 Something listed on the parts list as a " clutch module "  # 15 , does anyone know exactly what this does ?

Started to upload the complete manual the detailed wiring diagram came from. The modules are explained in the Glossary now posted

Update: Finally found it , after weeks of chasing this intermittent problem, tearing the tractor apart only to have it start working just as I'm ready to chase wires etc ... took me right where I started - the neutral switch ....the switch itself was working - the plug connecting it to the wiring harness was bad .....for whatever reason the plug had a lot of slop in the connection even when it was locked together creating a dead spot ......cut it out and installed new plugs .

 

This was not an easy find - thanks for the wiring diagrams Gary - .. really helped me narrow this down.

I'm having the same problem currently!
