why do gauges get wacked when battery put on
i was always curious of this, everytime i do something that requires the battery to get disconnected and then when it comes time to put it back on it goes on fine then i look at my gauges and theyre all out of wack. by this i mean the rpm and mph are pinned to the right and the temp gauge is usually just hanging, i have to keep taping the positive terminal onto the battery and hope it shocks it back to normal
and reason why this does this? is this normal?

havent tried driving to fix it, gonna clean the throttle body later today and will most likely try driving it before i try anything else

Some of my gauges will be maxed out, speedo temp. But everytime once i got up to cruising speed they popped right back

My tach & speedometer pegged when I replaced the alternator on my 2000 Blazer LS. The tach reset itself after I started the engine but the speedometer would not. I was able to reset/push the needle back to the left side by sliding a short piece of string trimmer line through and around the trip reset button. It took a little patients but it is working fine now.

From what i've read REXAZZ2 is on the right track - always unhook the neg first the the pos, when reinstalling the pos first then the neg - Key off for both disconect and reinstall of battery - surges the computer and other componets if done any other way - It can also surge the remote start and make it turn over while your trying to hook up the battery
