Good morning gentlemen,

This is a photo of my spark advance cable. Is it alright that it runs along the starter like this?

Thanks!

Hi John

Yes it is alright.
It pretty much has to run where it is.

Just be sure you have clearance between the advance cable and the live terminal on the switch just outside of the left edge of your picture. 🙂

I believe it originally had loom over the cable or made on to the cable to prevent accidental shorts. I used some from Restoration Supply the fit the cable very well.

Thanks, I thought that might be the case. I had though about drilling a hole in something like a black rubber ball, and positioning it on the cable at that point.

At assembly a fabric sleeve insulated the cable from the positive post on the starter switch. There also a rubber cap on the post to help prevent contact with the electroloc cable.

I put a boot on the end of my battery cable at the starter, this protected it from shorting out against the electrolock and/ or the advance cable. been very happy with it. 5737B

here is the article and testing i did on a few variants

Or you could use shrink tube on the advance cable.

For mine I use a small length of rubber vacuum tubing. That cable does move some when being pulled out to retard the spark.
