Alternator Tachometer Install

[Vossie]

Hi All.

so i just bought an aftermarket Apexmeter tachometer that is driven off of the alternator.

has any one else installed this unit before or one that also uses the alternator?

another question, which point on my alternator is the 'W' point? i have the original 2F alternator, externally regulated, hooked up. thinking @bj40green might be able to help out on this one

another question, what should my idle rpm for my 12HT be?

You should be able to run it off the neutral wire out of the alternator. It is one of the wires in the 3 pin plug, to check which one it is use a voltmeter and check the 3 wires. The wire with 7 volts with you engine running is the neutral, the other 2 are field and earth.

ok thanks.

next question, does anyone know how many poles in the alternator?
