I need a new timing light, I used it on a Chevrolet and it quit working, really. I see a lot of things about "Multi-Spark compatible". Is that a real thing? My old Actron CP 7519 seemed to work fine on all the cars with MSD ignitions. In any case, I haven't shopped for a timing light in a long time so I'd appreciate some input on what works well. Dial back would be nice, although I rarely use it. I see some have a tach. That would be nice if it is accurate. All inout appreciated. Chuck

We go through a ton of them on the dyno. Always killing one because a lead gets stuck up against a header or something. We've used pretty much all of them, MSD, Acton, you name it. They all work well with MSD stuff from what I've seen.

I personally don't like dial-back lights unless your balancer only has one mark on it. I've seen a lot of guys screw up the timing that way.

I don't like a dial back either and right now I'm using a cheap o Bosch one from Oreilley auto parts. I too have used the Actron and other similar lights on the dyno and I've never seen any real difference even when checking the timing at 6000rpm.

Brent and Dave,
Thanks for the replies. It confirms my experience with MSD ignition and plain Jane timing lights, they all seem to work. I normally don't use the dial back either but, when I encounter an engine with very few degrees of timing marks, the dial back is better than not knowing where the initial or total advance is. If I could find a replacement cable for my Sunpro (Actron) CP7519 I'd keep using it. Thanks again, Chuck

I have an MSD 6AL on my dyno and it doesn't seem to bother a regular cheap timing light but with that said I have seen one of those boxes mess with a digital dial back light and make it act wacky.

Dave, I've heard the same thing about digital display timing lights. Thanks for the input gentlemen. Chuck
