gauge flickering

[(92)cummins]

When ever i start my truck up and drive it the voltage gauge and temp gauge flicker, then when i hit the blinker they flick from one side to the other in the rythm of the blinker and im lost at what could be causing this

[collegekid]

mine used to do that, reset my crankshaft sensor and they went away and quit doing it

Are you talking about the crank position sensor and if so how do you reset it

[PToombs]

It should be .050 from the balancer. Just loosen the bolts and it slides up and down a little.

Ok I'll try that when I get around to it
