Timing light and MSD ignition

[67rcks]

I have MSD 6T box.

My timing light - http://www.muscularmustangs.com/tools5.jpg (old sears/craftsman with advance dial) fails to work.

It works with regular point single spark distributor. Is there anything that can be done to the timing light to make it working?

Hmmm… The light connects to the battery ± terminals, and the inductive sensor cannot detect the spark in the #1 wire? Interesting.

Are you using different wires too by any chance?

Wires? I am using autolite # 96205, the other car that this timing light works with is carbed 4 cyl. and uses some noname thin wires. MSD tech said not all timing lights work with their ignitions, especially those with advance button. Has anyone seen this light working with MSD?

I have a MSD 6AL and MSD distributor and the first timing light I used was a really cheap unit from Harbor Freight and it worked well enough to get the car started. I later got a nice digital timing light to dial it in better, so if you have to upgrade your timing light it isn't a huge cost. You could also borrow one from a buddy.

I have the 6AL and the msd dist. I also have the craftsman timing light with the advance dial (mine is about ten years old, dont know how old yours is) . It works fine for me , never had an issue. It may be that your pickup is not getting the signal from your wires. Pull a wire from the 4 cyl and mount it as your number one on your car and try that. Other than that, I can't understand why it's not working other than its that model msd unit and that particular timing light as the tech said. Good luck.

BTW my light is model 21023
