What would cause high oil pressure and high temp on my gauges? This is an 83 318ci with 60k miles.

I also lost my brake lights.

This van was set up for a camper and has electric brake system on it. It always had good oil pressure but it seemed to run cool, now I am not sure what is going on.

Thanks.

 

On the back of the instrument cluster is a voltage limiter for the gauges. If that went bad and is now allowing too much voltage to pass, your gauges will read higher. Your actual temperature and oil pressure are fine, it's just the gauges are reading high due to the excessive voltage.

Brake lights - Did you check all of the factory fuses plus any that might have been added for the camper conversion? Did you try jumping out the brake light switch down at the pedal to see if they work?

 

Brake or parking/marker lights? the connector for both go into the drivers side A-Post and then along the upper rail. The parking lights are into a 6 pos socket which also has the turn signals, rev lights, and the gas gague sender in it. The brake lights are powered by a seperate bullet style connector that goes into the same area. You can check that for power. You can also check that the other side has continunity to ground as well. The last switch to check is the brake pedal switch itself.

The dashboard voltage regulator can be replaced at a parts store. It was about $20 I think when I picked one up.
