When I turn my switch on the red light on the right hand side comes on. I think its the oil pressure light.it goes out as soon as motor starts. the red light next to it stays off till you start the machine then it comes on. some one said that was a low hyd pressure light. if so why doesn't it come on with just the key turned on. thanks

They both should be on, then go out when started.
The hydraulic pressure senders do go bad over time, i suspect it's nice and easy.

the right light does go out when you start the motor. the left light comes on when its started. sounds like I need a new sensor. thanks for the info. first experience with a bobcat.

right right should be hyro pressure and charge pressure combo. Left is in some units oil pressure and water temp. id look for the oil pressure sender and disconnect it and see if lt stays off and then look for water temp sender and do same. I think the sender wire color for your lt. in question is yellow/black stripe.

If it indeed is the hydraulic oil pressure/temperature sender, they are very common to fail.
