I have the "light" and "brake" dash warning lights on, and the "charge" warning light on dimly. All my brake lights are working. Disconnecting the brake reservoir connector and / or shorting it with a jumper changes nothing. One of its pins is continuous with ground, the other is also only if the handbrake is pulled. Otherwise it has 11.8 volts when key is in on position. Car runs fine. Any suggestions appreciated.
