i had an oil pressure gauge that was working fine... all the sudden it topped out! so i bought a new one hooked it up to make sure it worked and it did then when i hooked the rest of the wires for the light it topped out! and wont work no more. it will still power up and light up but is just topped out. the wires are also connected to the volts gauge next to it so i dont use so much wire. NEED HELP!!![:@][:@][:@]
