Fuse slot 12, HST Calibration

adegiulio · Apr 27, 2012

I was looking at my fusebox and noticed a fuse was sitting askew. I pulled it out just to check it, and when I put it back, I mistakenly put it in fuse slot 12. After starting the tractor back up it wouldn't move. I noticed what I did wrong and switched the fuse back to its original stop, but now the tractor still wont move. The sticker on the fuse box explicitly says not to put a fuse in slot 12, which makes me think its used by a diagnostic tool or something.

So, does anyone know how to recalibrate or clear this condition that I've created? I have a rented power rake in the back of my truck that needs to be lifted out (and used while rented) so time is a bit of the essence here.

Thank you for any input.

When the calibration fuse is installed, it erases the original calibration parameters from the controller. A new calibration must be performed to reset those parameters. If any of the sensors or potentiometers are out of adjustment, the calibration will fail. They will need adjustment before calibration will be successful. This is best performed by dealer that has the proper tools and info to repair.

Yeah, I found a thread online from someone who did it without the equipment. I sent them a PM, hoping they will get back to me. So frustrating since I have so much work to do..
