Gauge Question

When you did the MAD upgrade, you may have disturbed the factory splice in the black wire from the ammeter. One of the wires in the splice goes to the voltage limiter for the gas and temp gauges. The limiter is built in to the gas gauge and provides 5 volts for the gas and temp gauges to function correctly. OR possibly the limiter decided to take a dump.

Edit: I misspoke about the splice and the wire to the voltage limiter. I was looking at the wrong in harness splice! See my follow-up post
