Bobcat 553 interlock control voltage output.

[ORSTech]

I'm getting about 8 volts to the hydrostat travel lock solenoid, coming directly from the interlock contol box. I don't belive this is correct. What is happening is: the solenoid is de-energising while in motion. I assume I need a new interlock control box, but know the specified voltage would help. Does anyone know? Thanks, Chris

Its possible you have a bad ground too. 8v may be correct, they do run their coils at weird voltages..... I assume this is the lift arm lockout? and not the park brake rite?

The lift arm lockout was already screwed up in the interlock box, so I bypassed it to keyed power, but now that the park brake is turning on. So It's definetly the box that's the problem, the coil is fine, I tested that. So we're just getting a new interlock control for it. Thanks for the info!
