Hello all- I have a a 334G ser 234514534 that the two speed travel quit working. Any Bobcat gurus have any tips or insight. I have a shop manual but the electrical schematic is incomplete. Any advice is appreciated. Thanks!

Good day
According to my information, the two speed is controlled by a solenoid valve No.49 on the schematic I have read, the second unit from the accumulator. I suggest first check out if this is getting a signal when you switch. The coils are common, so you can switch to eliminate. My wiring schematic is not so good, if you like to share the correct one I can try to help some more.
Kind regards

It is spool #7. No power is going to it. When you press the 2 speed switch button the controller "rabbit" icon does not come on either. I've checked the two speed switch button with an Ohm meter and it's checking good. I then suspected the controller was bad so I switched out the controller with a known good unit and still nothing. It's a witch hunt.
