Triumph TR6 - Over Current showing on Ammeter while driving

Today I took out the 69 TR6 for the first time this year.

I noticed while driving that the ammeter was reading very high while driving. This is uncharacteristic as usually the needle is just slightly +ve. (My gauge does not indicate voltage but current and has no numbers on it.)

I assume the alternator regulator has failed. Anyone disagree or have another opinion?

And any opinion on if I will damage the battery, coil, radio etc. if I take the car for a full day ride tomorrow as planned?

Thanks for your help

Hello Michael,

Hard to give you a perfect answer. But my car do that when I turn on headlamps. This meseaure the amount drain by ammeter. The best way to check thing is ti use a voltmeter. You connect on battery. At rest it should give near 12V. Engine running between 13.5 and 15V.

Cheers,

Thanks Jean,

After my drive yesterday it seems to have settled down and returned to normal. For the first couple of hours it read high and I kept it down by using headlights. By the last half of the trip it seemed to correct it self and read as it used to. Probably some other failure about to happen. Maybe the alternator is going.

There was no problem starting the car after running it so the battery is charging.
