Powermaster problem.

I was going to take my 86 GN for a ride,but when I started it up the brake light went on and didn't go off. I pumped the brakes 15 times with the engine off and took off the reservoir cap. It was low on the fender side. I added fluid to match the other side. Still a hard pedal. Any ideas???

Pm

Look for a leak. Check the front control arms where the hard line connects to the rubber line to the wheels. Also check the rear axle where the line T's to go to the rear tires. Once you find why it was low it is time to bleed the PM and the lines.

Check you fuse. I'll bet it's blown.
If it is, you need to run the diagnostic procedure to determine why it blew.

Are you talking about the fuse prw brk in the fuse panel? 30 amp?

Yep.
That fuse blows from the motor running too long.
It draws too much current, or just has a short somewhere.
Either way, if it's blown you have some investigation to do.
