My 90 SC brake system is driving me nuts. Both brake lights are lit and stay lit as long as the ignition is on. I removed the pump relay and jumped the contacts. The pump comes on and pressurizes the system. I checked the voltage on the contacts for the relay coil and it reads about 11 volts and goes to zero when the pump pressurizes the system, so it seems that the pressure switch is making and breaking. However, the isn't enough current to activate the relay. I bought 2 service manuals only to find out that the ABS system apparently operates by magic as I can't find any indication in either manual that there is any wiring associated with it . The car has less than 100k on it and runs great but stopping this great hulking mass is sort of a problem.
Oh, I did replace the pump relay. It was cheap and available..........and did nothing.
Any thoughts?
