I found that I have a new problem today. when I turned the car off the car the brake pump stayed on. I had to unhook the battery to get it to stop. when I hoked the battery back up it started up again! does any one have any idea what's wrong and how to fix it? and by the way its a fully loaded 88tc.
I'm not familiar with the circuit, but it sounds like a relay is shorted out. A decent manual should tell you the location, and they are easy to test.
Booster relay is stuck on. Just look over at http://www.Turbotbird.com and do a search for brake booster relay and it will give you the location and probly a part number.
