We Don’t Get Fueled Again !

Here’s how to test the fuel gage.

Remove the sender wire going to the gage.

Use a potentiometer with a value of 90Ω or the closest you can find.

Connect one end the potentiometer to the gage from the location you removed the sender.

Connect the wiper of the potentiometer to ground.

Turn the key to RUN.

Slowly adjust the potentiometer from 0Ω to 90Ω.

If the gage is bad it will exhibit the problem you have.

If the gage is good it will display a smooth transition from end of it‘s range to the other.


Happy Racing!

When you see fog lights on in good weather beware. Low performance driver ahead.

How bout those nitwits too scared to drive without headlights in the daytime, and the nitwits that need headlights for a little rain
