myv volt meter gauge is playing up :(

[Nic92]

ok so i have the car on acc and it works perfectly fine, i see the voltage drop after playing the radio, and then when i start the car it bounces and stays on 18v (which is the end) and sometimes it bouncing front and back, i brougth a Glowshift asuming that was a good brand.. already replaced once because of the same problem, i thought it was teh wiring to bat how it was all messed up.. but now its all fixed and its still fked so.. any ideas?

im thinking of just taking them out tbh

this is what it does as soon as i start the car but works when i turn of the car with accessories

get a multimeter and check the voltage at the back of your gauge, its most probably a stuffed gauge cause if your alternator was putting out 18v lots of things in your car would be fried

i know its not actually putting out 18V is why the actual gauge is playing up.

that kinda gives you your answer, how much did you pay for the gauge?

check it with ur digital gauge on ur cluster if u dont have a multimeter, if theres a differences put a different gauge in as u dont really need them since u already got 1 haha

meh i took the gauges out anyway, might get a hsv gauge pod & new gauges later.. the one i have now sucks

Sounds like noise. Try putting a cap across the terminals.
