Easy there dudes, it may have been KMS who twisted the knob too far. If he goes to the dealer, they can give him a crash course in how to operate it!
I think that one of those funny looking wire fuses controls the throttle but it has been a long time since I ran one and can't remember for sure.It seems the fuses are near the manual throttle toggle switch and there may be spares there as well.
I have repaired the computers in them before too,seems like the vibration over the years cracks the solder joints on the circuit boards and I just needed to reflow the solder to repair them.We also had a 2800 that needed the same thing.Ron G
The fuses that I remember were just a flat piece of wire on a plastic form maybe?They were ganged together in a fuse block and it seems that there were spares in the cover maybe?In any case you should be able to see a blown fuse.....swap a good one from the lights etc to see if it helps.The LinkBelts I have worked on were from the mid '80s.
I think they were behind your right elbow when running the machine.If you have to pull the computer I will check it out for you.Ron G
You cannot tell if anything is is blown by looking at it.The next logical move is to get a wiring schematic and a meter and start tracing the circuits that affect whatever your percieved problems are.I think Tyler Equipment is still the dealer.Ron G
