[Fot] Sprint Alternator

[Scott Janzen]

Steve Smith sent me wiring instructions for the one I just installed, which 
worked great over the past weekend. The large terminal with the threaded nut 
takes a (fat - I ran 8 gauge) wire straight to the battery.  This alternator 
also has a receptacle for ana electricical plug from the Chevy Sprint wiring 
harness - there are three spade connections within the receptacle.  One of 
those needs to be connected to the ignition circuit, so that when the 
ignition is on, the alternator's built-in regulator is recieving a signal to 
tell it to charge.  When looking at the connections, the three blades form a 
"U", with two blades parallel and one perpendicular across the bottom of the 
"U".  Connect the power source to the blade on the right side of the U and 
it should work fine.  The bottom one is not used, and the left one can be 
hooked up to a trouble light - if the light is on your alternator is not 
charging.  At one point I had a link to another site that explained why this 
works, but can't find it now.  I did not use it, in any case.  If your 
friend is running autocross or hillclimbs, for less load on the engine just 
pull the wire off the blade connection - the alternator is no longer being 
told to charge - no 45 amp drain on the engine power and your car runs off 
the battery for a little while- plenty to power the ignition for an hour or 
so.
