If any of you guys install isspro gauges and they work one day then dont the next , and start causing crap like instrument panel and tail lights to go out , check the "two bulb" gauges where the + and - terminals cross the back of the gauge for the gauge lighting . They are within 1/32" of each other and are held on with one rivet so they pivot slightly . Guess I hit a bump and they touched each other causing me a whole afternoon of gremlin chasin and headache .... Stick a screw driver in there and give it a twist to seperate the two and your good to go . Hope this helps and maybe save ya some headache and time .

 

Put some electriical tape on anything that could short.

 

Electrical tape on terminals wouldnt have helped . + and - are on opposite sides of the gauge from each other but there are also 2 bulbs which also are on opposite sides of the gauge . The terminals each have a slim little bar that crosses the gauge to feed the opposing bulb its + or - signal . And they cross so close to each other its ridiculous . They pivoted and shorted . The connectors never touched each other , just the little "bus" bars that they are connected to .

 

oh....
