[DeTomaso] Connecting A High Torque/Gear Reduction Starter In A Pantera

[SOBill at aol.com]

Mike,
 
 
Boyd411 wired his new starter just as you suggest. He  found that the 
starter cranked a cold engine slowly and could barely  crank a hot engine. When 
he changed the wiring for the solenoid of the new  starter to be activated 
via the OEM solenoid direct to the battery his  starter performed perfectly 
hot or cold. It seems the solenoid of the new  starters require more current 
than the OEM ignition switch START position wiring  can handle.
 
The OEM solenoid serves as the source of battery voltage  measurement for 
the alternator regulator and can be used to activate the white  wire of 
Duraspark ignitions when starting the car as well as bypassing the  ballast 
resistance. The Duraspark white wire retards the ignition timing when  the engine 
is cranking. This retarding the ignition during cranking makes life  easier 
for the starter.
 
If you have an after market ignition with no ballast resistor and a  one 
wire alternator you can dump the OEM starter solenoid.
 
Have fun,
