Firing an engine out of the car, how to?

I'm not up to speed on electrical systems. I have a 401 nailhead Buick out of a '66 wildcat that I'd like to fire up & check out. I'm building a simple stand to be secure with a panel for switchs etc. but I don't know how to wire it. Can anyone supply a simple diagram ?

OK, seriously now ...

Get yourself a universal ignition switch, something like this one.


Standard (Blue Streak) part number US14, or NAPA (Echlin) part number KS6180

Terminals are all marked
BAT at "6 O' Clock" position
IGN @ 2:00
ACC @ 10:00
"ST" (START) is the center stud

BAT: connect to a (fused) "always on" power source or even to the POS terminal on the battery. Place the fuse as close to the power source as possible.

IGN: connect to all devices that you want to power up with the key in the "run" position. The ignition coil will most certainly be one of these devices. IF you are running a point-type distributor, you will want to add a ballast resistor in order to avoid burning the points or damaging the coil.
I also have all of the guage lights and an electric fuel pump attached to this stud.

ACC: it is not nessecary to run anything off of this stud, unless you intend to play a radio or something.

ST: run a wire from here to the "S" terminal on your starter solenoid. It supplys the juice to energize the solenoid and engage the starter. There might also be an "I" terminal on that old solenoid, and use of it is kind of optional. It's there as a by-pass ignition circuit, designed to deliver a full 12V to the coil while cranking. As soon as the key is released from the cranking position, power would go through the other circuit from the key switch ... through the ballast resistor.

Come to think of it ... I'm not sure if that coil was designed for use with an external resistor or not. Most are labelled "Use with external resistor" if one is required. You could probably measure the voltage on the "-" side of the coil while cranking to determine if the distributor is "seeing" around 6 Volts.


NAPA (Echlin) part number IC12 ignition coil

Make sure that the cake-pan is well-grounded, and you should be good to go.

yu dont need that, you just need to run tw small wires real quick to the battery post, and the two cables.


all you need is the solenoid wire and wire to the coil or HEI

i d this all the time with engines

very simple

just attac hthe wire to the coil or hei to the pos battery post

and the wire to the solenoid you touch to the post to crank it over

let it go when it starts


open manifolds and a radiator and hoses are the only thing else needed to run it out of the car, or as long as you want
