pyro flickering while breaking????

[railhor5.9]

its installed right, but everytime i push in the brake the pyro fickers.... moved the power straight to the battery, the ground to the battery as well, wats wrong with it?????????????????????????????????????????????????????

What brand of gauge? Autometer?

My thought would be a bad ground, but it sounds like you covered that. Where do the wires for the gauge run? Sometimes I'm kinda careless with my routing, could your brake pedal assembly be rubbing on the wires for your pyro?

Bad ground between the engine body/frame will do that. You might try running a ground from the VR to a manifold bolt.

would my tach thats strapped to my alt do that too?? does anybody else have one of these tachs set up like that?? everytime i turn on my lights, it flickers like crazy.

I have the auto meter tach with the alternator pickup, I have noticed it move slightly with the engine running when I first turn on my lights but that's it for mine. With the engine off and the stereo on with the volume up the needle will jump to the music.

It seems the autometer stuff is real sensitive to voltage changes. Not a good thing on our lousy wiring system. My isspro egt gauge on my 93 will do some funky things when the grid heaters cycle sometimes.

same here

Yup, and Rumblefish's tach never did anything weird in my old 91.

maybe it has to do with the location of the ground.. like how good its grounded?? mines grounded on the brake release bracket thats bolted under the dash..
