Brake pedal press causes voltmeter drop
#1
![Default](/forum/images/icons/icon1.gif)
1994 4.0 coupe, USA spec.
When I press the brake pedal the voltmeter gauge drops a couple of volts and returns when I lift off the pedal.
I have heard of this on another forum. Suggestion was a bad/poor (white) multi-connector under the steering column with a large brown earth/ground wire. Cut off the connector and hard solder the wires together.
Anyone else had this problem, root caused it and cured it?

My '94 is/was doing that Voltage drop with the brakes uuntil I replaced the brake lights with LED types. The voltage still drops but not as much. Now the turn signals really cycle fast because there isn't as much of a current draw for the flasher. I have the resistor pack to put on the turn signal but just don't have as much time lately to mess with it.
I did notice that the abs relay does cycle and cause the voltage drops also. I've seen some posts about the ABS system pressure vessel having leaks that may cause the ABS to cycle the pump to build pressure again. Another when I got time project.
