This GT19 showed up for sale. Which I had been looking or planing on building something with more power to run my 60" deck and the vac bagger.
I've been working on it for about 2 weeks, fixing a bunch of stuff, glad I have a GT18 basket case that I could steal the $$$$ front PTO setup out of, and trouble shooting the electrical system.
I've come to the conclusion that it's a 931026 and it originally had the transistor interlock module board, which is on my GT17, that was replace with the 531160 or 531236 interlock module service assemble.
Sometimes I could get the PTO's to engage, if I turned my head just so, held my mouth just right and wiggled the PTO switch like this, but now I get nothing. If I get off the seat with either switch pulled the engine dies, like it should. After hours of probing w/ my VOM and reading the electrical section in the repair manual.
I'm beginning to suspect the round time delay module w/ the 3 yellow, black, and red wires.
If I jumper the red wire to ground, the relay clicks and then if I pull the PTO switch the clutch engages.
My question is, does anyone know the part number for just the time delay module that comes in the 53123600 interlock module service assemble that is $185 from Jacks.
I don't need the relay and wiring, just the time delay module.
My guess is that a $120 53125500 module from the newer 931029 GT19 Could be the correct part but I would hate to spend that kind of money on a guess.
I was going to take the one off my dads GT20 but it has nothing that looks like what I have. Then again maybe the 53125500 updated module is a time delay and relay in one and he has already replaced it. If he wasn't on vacation in Hawaii for 2 weeks I'd ask.
Then again, for $100 I'll tear mine apart, if I can separate it from all the black goo they filled it with, find out whats what and build my own.
While looking through the PM-931000.pdf looking up bolt lengths for the 60" deck, it shows the 531236 Interlock Module Service Assemble and lists all the part numbers. 030843 is the Time Delay Module which updates to 53125500 $119.75
