Does it have electrical wires to the back of it or does it have a drive cable?

On the back of the alternator there are 3 wires,

1. is the main power supply wire to the battery via the starter
2. is the wire for the charge light
3. the last is for the rev counter.

the rev counter is operated by the voltage generated by the alternator. put a multimeter on the alternator out put main supply and it should read 13.8 to 14.8 v.
The second small wire for the light should read 12v with the engine off.
and the third wire will have a varying voltage depending on the engine revs............................................................................................
