Re: [ihc] RE: Relaying George's power

[George B Humphrey <xgbhx@xxxxxxxx>]

John and Jim,
	I think I am understanding this. First of all, yes, I do have a Ford
solenoid. 

	The Bosch relay has two trigger inputs? One triggers during cranking and
one triggers during run? The run trigger will also prime the fuel pump
before cranking, correct? 

	Something I don't understand. Aren't both sides of the Ford solenoid, in
a sense, hot? It Just takes the ignition switch to complete the circuit.
If I attach a trigger wire to the side that runs to the Delco solenoid,
it completes a circuit; Battery- solenoid- relay-ground. Wouldn't this be
the same as connecting the trigger wire to the battery?

	I also wonder about the resistance wire. If it is only used during
running, why didn't the fuel pump prime when I tried to use the coil as a
trigger? I got nothing in run or crank.
