Electrical twitch !

[BT SNAKE]

I have noticed of late that I have a twitch in all my guages.
This only happens when I put the brake on or the turn signal.
If I put on the turn signal all the hands in the gauges twitch in sequence with the turn signal blinker. I don't know why I never noticed this before but now it really bugs me. Any ideas as to what I can look for that's causing this ?

Hershal,

Right off the top of my head, a loose or poor electrical connection. As the brake or turn signal bulb lights up, it draws more current. This current is passing through a poor connection which in effect is a resistance in series with the current flow. This resistance will drop a few volts of electricity. This drop of electricity is felt by the gauages and results in the flicker you are seeing.
This connection will be one that shares its supply of 12 volt power to both the instruments and the brake lights. Heck, it could be the main power connection at your fuse box or .......anywhere. Just start looking around and tightning screws, checking crimps, .... you get the idea. It will appear to be very elusive, so just keep plugging away until you find it.
Good luck

PS if you own an old analog voltmeter, you can use this to locate the fault too. With the black lead of the meter to the engine block, start measuring the voltage at the battery terminal while the turn signal is flashing sway. Start moving along the 12 volt line until you find a spot where the meter starts to flicker slightly. You've found the spot.

I would check your ground connections in the brake switch circuit and your turn signals.
Good Luck!

I'm gonna give it a fresh start in the morning. I am not an
electriction even though I wired this car. I follow directions
pretty good though. Hopefully I'll find the gremlin sooner than later.
