My '74 has a 19mm Master Cylinder.
The dash warning light has been flashing incessantly - I disconnected it a while ago. Tonight I was busy breaking my horn mechanism in the steering wheel (IMG:style_emoticons/default/blink.gif) and I decided to try to reset the button on the MC to stop the flashing. Here's the deal. With the car on the ground and a flashlight, I managed to find the reset button. Hit it, reconnected the warning light on the dash, and it now functions correctly. (stops when the parking brake is released) However while I was reaching in there, I accidentally disconnected what looks like a Ground wire. I don't think I have any hope of finding where it connects without taking the car to a shop and getting it up on a lift, so... What is the risk of driving it with the ground wire disconnected from the MC? I don't think I've ever fixed something on this car without (IMG:style_emoticons/default/sheeplove.gif) something else. If it's not one thing, it's another. (Or as Freud put it: If it's not one thing, it's your mother.) |

Is the wire connected to the master cyl. switch brown with a yellow stripe? It should be connected to it if your switch has a reset button. On the orignal switch there were two wires. The "ground" you think you disconneted is solid brown and IS a ground, except with the one wire switch it is not used...connects to nothing....
