Just to be a picky person - it's TACHOMETER. Not tacometer. We don't care how many tacos you have.

Mmmmmmm tacos

Not sure what you mean that it is charging. Anyway, the A3 tach gets 24 volts from the system, has two wires to the sender in the bell housing and that is it. Sometimes the sender gets a little loose and does not receive the signals (one pulse per tooth on the flywheel) and sometimes it is a connector problem.

They are not easily available on the market so you will have a time if you can't get it to work. I finally bought a civilian unit with a digital hourmeter, it is working great.

The charging thing was me thinking the TACH may be geting its signal from the alternator.
Thanks for the info now i go look

I would pull the sensor out of the bell housing and check to see if a piece if metal is stuck to it. It is a magnet and the metal would cause it to stop reading the teeth on the flywheel.

Riddle is right. The sensor is real easy to remove and check- if you have the engine and transmission lying on the garage floor. If not it is kind of tough.

You can get to it by going over the driver's fender. You will see the two wires going to the bell housing. Or, you can remove some of the firewall plates and get to it from the cab.

Haha! Yea it is not very fun to get to. I went over the fender.

You could use a multimeter on the wires coming out of the sensor (maybe dash if you read the wiring diagram) it should produce a ac voltage as the flywheel turns.

Crack it wit ahhh HAMMER....... That fixes everything

Tacometer? Is that the instrument which displays the total number of tacos you have eaten while drivng your deuce?

 

[doghead]

Yes, They had them at the restaurants that I ate at while out in San Diego.

 

[gungearz]

No, no, no, a tacometer is the meter on your dash that tells you how many tacos it takes to make for your deuce to run. I don't know what he's talking about. He said he has an A3. Tacometers are on A2's.
