Re: Another HEI Application

"I have a Crane H1-6 multi spark unit on the shelf and was thinking of adapting it for my '47. I was thinking that I could use a 6 volt positive ground to a 12 volt negative ground unit as the power source. I have a Crane Hi-6 on my old 84 Volvo 240 with point ignition and it works very well. Any thoughts?"

As long as you can get a negative 12v timing signal to the control box when the points close I see no reason why this wouldn't work. The points or ignition module are merely switches in this application. I have to admit that I am a rank amateur at this type of work. I merely disconnected the one extra wire in the Pertronix, positive ground ignition module as it was the quickest and easiest way that I could figure out to get the negative 12v signal that the Jacobs control box required from what I was working with at the time. I ain't a mechanic nor an engineer. I adjust real property insurance claims for a living. That's one of the many reasons that I appreciate this forum so much. Even with it, since I decided to stop letting other people screw this car up and start screwing it up myself, I sometimes wind up having to do stuff two or three times before I get them right. This was one of the FEW things that I've done that worked right the first time.
