On my 1999 Hunter 410 the oil pressure indicator instrument light on the engine control panel is not working. It is either a burned out light bulb or a loose wire. All other instrument lights on the panel are ok. Before I start taking everything apart, I was wondering, if the lense can be prayed off from the outside to get to the bulb. If this does not work, which screws have to be removed to take out the assembly from the arch? The ones on the white outer plastic ring or the ones on the black panel? Any one who already had this problem and replaced a bulb, I would appreciate your comments.
