I disassembled the distributor to discover that I had made a mistake. That was a sign that something was not right. I was definitely moving it more than 10 degrees (L10 is supposed to be 10 degrees of distributor advance which is 20 at the crank). I decided to get my old protractor to measure how much I can move the distributor rotor. After some tweaking it was down to 40+ advance. Then I tested at above 3,000 rpm when the multiple sparks are supposed to be phased out and it should transition to a single spark. From what I was reading I should get a fluctuation of a few degrees but not off by that much. I was seeing advance up to 50 and I started thinking that this could not only be due to a timing light error. No problem with the one I have now.Īfter reading more and more about timing lights and multiple spark ignition i started thinking that something was fishy with my system. The first one of these I bought was and the dealer replaced it. If this is what you had, perhaps it was just a faulty timing light. It is fully adjustable, with a good tach and digital display. It can be used on ALL 12v negative ground systems, either points or ALL electronic ignitions. I've always said when it come to electronic stuff, I'm lost and that's my disclaimer! While it produces around 40000 volts, I don't believe it is multi-spark. Does that come from the MSD coil? I am familiar with my Pertronix Ignitor II and coil. To be totally honest, I am not familiar with CDI multi-spark ignition. It does claim to be CDI compatible, but it is not adjustable nor does it have a tach from what I saw online. Your choice, but I would pass on that one. Tony, I looked that timing light up out of curiosity and I hate to say this, but the reviews are not too good for that one.
