66 Dart gas Gauge

You could take four "D" batteries in series to duplicate the current. 6V won't hurt the gauge.

Please read it all, because I don't exactly know what your gauge cluster looks like.

3 POSTS SCENARIO

• Pull out the gauge cluster
• follow the printed circuit pattern, on the circuit board, to the mounting screw to determine the "ground", trace it back to one of the three fuel gauge posts and attach the neg lead to that post
• of the three posts coming out of the fuel gauge, the other two posts are "voltage limiter in" and the other is fuel gauge. You can put the positive lead to either. If the gauge does nothing ( give it a second or two ), move the positive to the other screw. If your gauge is good, then the gauge will move to "full".

CAN TYPE VOLTAGE LIMITER

• Pull out the gauge cluster
• follow the printed circuit pattern, on the circuit board, to the mounting screw to determine the "ground", trace it back to one of the three "voltage limiter" prong sockets (voltage limiter pulls straight out) and attach the neg lead to that prong socket ( you can use the metal of the gauge cluster, but the socket is better)
• of the three prong sockets of the voltage limiter, the other two sockets are "voltage limiter in" and the other is fuel gauge. You can put the positive lead to either. If the gauge does nothing ( give it a second or two ), move the positive to the other screw. If your gauge is good, then the gauge will move to "full"

• You won't hurt the limiter or gauge if you choose the wrong post, as the only effect would be to cut your battery voltage approximately in half. A paper towel tube or flashlight body can be used to hold the batteries

That's my thoughts. I hope this helps you.....it's what I would do.

Does someone else want to tell me this will NOT work? Let's help the man out.
