There are most likely tons of folks who could explain it better but here is
my understanding and my reasoning...
The Barry Grant Fuel pump has the ability to pull 25 amps on start up.. and
he recommends you use a Constant duty solenoid which looks just like a ford
solenoid except that it takes a 5 amp circuit to start it or turn it on and
then rather then releasing it stays on with minimal amperage draw.... this
is the best way to give a high drawing system power according to several
sources I have....
The wiring issue is really about not being able to find squat this other
guy did to the car before I bought it... he had used a single color and no
labels.. The wiring harness really isn't a harness at all it is simply a
supply of quality wires that are color coded and the give you a basis to
start the system... they don't have anything else.. some cute wire ties..
and so on.. this thing is a $50 dollar option from AUTO ROD... not Rod
ware.. my mistake... it is just a place to start.. you sould see my mess
that I made of the shop floor with the old junk...
Basically I wasn't liking the fact that I had to tap the gages to make them
work and the switches were nothing but the finest Wal-Mart quality....Yeah
it was time to do something permanent... All of the systems I am putting on
the car are long term systems that I am going to use to build the Healey..
but for now I am learning my happy butt off....
