Having just completed my second partial restoration of my Tiger to include new wire harness. I have noticed a drain on the battery so I installed a cutoff switch for the time being and something I wanted to add anyway. I recently turned the battery cutoff on and my buddy noticed the gas gage needle rising WITHOUT THE IGNITION SWITCH TURNED ON. While I can probably figure this problem out I would love to get the answer and spend less time dealing with it. When I rewired the car I elliminated the voltage regulator using a 1 wire alternator, I'm sure this has nothing to do with the situation though the wires that normally hook up to the regulator are now capped off. Again probably not an issue. Thanks for any input you might have.
