[Tigers] Alternator wiring

[Jay_Laifman at countrywide.com]

As indicated, most are not actually single wire.  On mine, there are 
three: B, S and L.  S gets looped over and connected to B.  B goes to the 
battery side of the starter solenoid.  L goes to the light on the dash. 

This L is very important though, and is not just the "light" it also 
energizes the coils for the alternator to actually charge.  The other wire 
to the light must go to keyed power.  So, when the keyed power is on, the 
power flows through the light to the coils which lead to ground and 
charges the coils.  When the alternator then spins, the power shuts off 
the light.

Note that my alternator is a Hitachi off of a Nissan Z.  I pulled the 
wiring diagram of the Z and found it wired exactly as above, including the 
looped S to B.  It did have one more item though.  Parallel to the light 
itself was a resistor.  This must allow for the charging to still work 
even if the bulb blows.  I never put in a resistor and my bulb has never 
blown.

Before I had this wired correctly, the alternator would not charge 
immediately upon start up and needed a blip of the gas to get it going - 
which charged the coils from the other end.
