switched 12 volts
I'm installing an HEI in my 67 Coupe and would like to know the best
place to find a switched 12 volt source. Thanks |

No ballast resistor in a 67. Just the pink resistance wire from the
ignition switch. I just cut it at the back of the switch and ran my wire to the HEI, now i have the 12v.

I guess one MIGHT, in a WILD stretch of the Imagination, call that a BALLAST resistor, huh? Sheesh! It's NOT what it LOOKS like, it's what it DOES! Anyway, good on ya for solving it. -- Yeh, I'm a Krusty old Geezer, putting up with my 'smartass' is the price you pay..DEAL with it! |

Believe it or not, but i put a meter on a few of the fuses and they all
dropped off when the key was turned to start. Even the big post on the back of the ignition switch dropped off.

I didn't mean it the way it sounded about the ballast resistor. I know
what you were saying. Resistor wire/ballast resistor all do the same thing. Strange thing is, when i got the car, there was a ballast resistor on the right inner fenderwell. Not hooked to anything, but it was there?? JF Backyard Mechanic wrote: > JF > wrote: > > >>No ballast resistor in a 67. Just the pink resistance wire from the >>ignition switch.

It actually made a difference (though I have no idea why).

Nope, never thought of that. But i will keep that in mind for future
reference.

The internal resistance of the battery coupled with the high amperage required to turn the engine over will cause a voltage drop. ...or are you talking about just turning the switch to the 'run' position and you get the voltage drop? If you're turning the engine over, there's just no way to avoid a voltage drop and the voltage you read could be as low as 6 volts. Of course, the wire in the wiring harness has a certain ohms/ft resistance that could also affect your reading, but it wouldn't be significant unless you were reading the voltage right off the back of the starter itself. |
