Default Best Timing Light

I need to buy a new timing light. Mine is very, very old. Anyone got a recommendation for a reasonably priced, adjustable light that will work with MSD multi-spark ignition??

I just purchased a Sears non adjustable light for less than 40$. Works well and has a bright light you can see outside. Don't know about the adjustable part though.

If I were you, I'd get the timing light with the timing advance. I have this one from Summit Racing ($55.95) and have had no problems with it.

Harbor Freight has one for $29.95 that is adjustable and has a bright light.
It is THE SAME light sold at SEARS for $49.99

Does MSD ignition require a special/different timing light? if so Why?

I like this light but the Summit web site says that it is "not compatible with multi-spark ignition" (under notes). Are you running multi-spark ignition??

I am running MSD, I will be adding MSD distributor so I will need to set timing. I didn't change timing (or I don't remember) when I added MSD box.
I have a Craftsman timing light (no advance).
Just want to know if MSD requires something different? Better?
What are you guys using with MSD?

Recommendations for what will work ??

Just a guess, but I think that "multi-spark ignition" probably refers to dual point ignitions that were popular on high performance cars in the 60s, prior to the advent of solid state electronic ignitions (like MSD). I've got a Sears adjustable light that works great with the Pertronix setup on my 69 Mustang. My Vette is the stock single point distributor, so I suppose it would work fine with that too. I doubt that MSD would require a special timing light.

I've just emailed Summit, on this light, asking them if this will work with MSD ignition. Hopefully they will reply. I'll post if they do.

I just got a new light this year myself. Its Innova 5568 digital. I bought it for $100 from Amazon. What I like about it is not only an advance timing light but also has a tach and charging system read out as well.

So in one device you can set it to 36 deg and then rev until you hit it and see the exact rpm right there on the light. It is a little more but it is nice. Not sure about MSD.

This is the light I use. I like the tach and charging readout. The dial back advance is very useful if you do not have a degreed balancer. You cannot check full advance if you do not have a light like this or a degreed balancer. Checking initial timing is like kissing your sister. Pretty much worthless.

Yes it worked when I had a Multi spark ignition and it works on my buddys MSD distributor.

I have heard back from Summit and they confirm this light doesn't work with MSD. To bad, it looks like a good light for the price. I will check out the Innova. It's more than I wanted to spend but as you know "you get what you pay for". We'll see.
I'm open to more suggestions.

Aha! Now I know what the advance is for on the new (to me) lights. Thanks for the info.

There is an Equus/Innova light without the charging feature for around $80. I use my Sears digital multimeter.

With all due respect to RagTop69, most of the above is a bad guess. MSD is a brand of Capacitive Discharge or CD ignition. The technology fires several times over a short period of time at low and midrange RPMs as compared to points or HEI which fire once. (MSD=Multiple Spark Discharge) Because of this, many timing lights cannot accurately "see" the timing. It is the same reason that when running an electric tach with an MSD box you must connect to the tach output on the box rather than the negative side of the coil.

Regards,

Rob

Well ok, I bit the bullet and ordered the Innova 5568. Thanks to Johnt365, Gordonm's advice, and the fact that it comes with a nice case, I took the plunge. A few extra bucks won't kill me. It gets delivered end of next week. Thanks for all your help.

I don't think you will be disappointed... EQUUS/INNOVA is making some very fine and well respected electronics for the automotive industry.
http://www.equus.com/

If you have a '96 or newer vehicle you will find their code readers to be a very reliable and useful tool for any modern tool box.

Good luck... GUSTO

I am looking at buying the Actron CP7529 Digital Timing Light. I have one question will the cable reach to the battery in my '79? Also if anyone has any pros or cons on this it would be appreciated.

Thanks,

Rick

Rick
Use the battery positive terminal on the back of your alternator, put the negative clip on an intake manifold bolt. Also, it is usually better to attach the #1 plug wire pickup near the distributor. No heat from the exhaust manifold to melt anything. Also pay attention to the pickup...it is probably directional and have an arrow pointing towards the spark plug end of the wire.
