I've noticed that sometimes when I start my engine, all the gauges (speedometer, tach, oil pressure, volts, fuel) jump straight to their maximums for a couple of seconds, then go down to their normal readings. Is that normal?

 

yes

 

Mine never did for ten years then the gauges started pegging on start up a couple of months ago.

Then I replaced my OEM battery and they stopped pegging.

 

Mine does it to I drive mine about twice a month.. I was thinkin the battery to b/c I still have the factory one..

 

Thanks guys. I was kinda suspecting the battery as well. I'm thinking I'll have to replace it sometime this winter.

 

Mine did that one time leaving the store, the next time I went to start it the batt was dead. I'm with everyone else...batt.

 

yea it will do that if you unhook the battery for a while then reconnect it. Even with a good battery.

-replace battery soon-

 

i agree with patman.

 

Battery

 

your battery and or alternator is on its way out

 

This is triggered by a drop in battery power making the gauges go back into calibration mode where they "peg out" This also happens when you disconnect the gauges and reconnect them.
