![]() The only real downside is that this test light relies on operator skill for accuracy due to its analog nature. ![]() Worth mentioning, the detachable cables can be replaced if damaged, which is a possibility when working around a running engine. Besides, the grippy handle with a built-in protective guard ensures a safe and comfortable operation while using one arm only. This device will easily fit into any engine bay, thanks to its slim barrel and compact shape. The analog advance dial is very helpful when checking base timing and when advancing or retarding the ignition. It will enable users to diagnose a no spark condition, check the timing advance or retard and perform a skip circuitry test. Still, with features and functions that allow tackling even the most demanding tasks, it is more than capable. The firm also has a range of timing lights in its lineup, with the 3555 model being the entry-level variant. Innova is a manufacturer producing specialized tools and equipment for automotive enthusiasts and professional mechanics. What to Look for When Buying a Timing Light.After all, no need to pay the big bucks for a techy model that you won’t really use. Consequently, make sure to correctly evaluate your budget and needs before you start shopping. Some work better for older cars, some are better suited for beginners and some of them will really only be useful for full-fledged mechanics. You’ll see that we tried to select a little something for everyone. To help you find the right model for you, we reviewed and curated a selection of some of the best timing lights out there. However, like most other tools, there is a wide range of different models available on the market. Since they have such an essential task at hand, timing lights should be precise, reliable, and easy to use. This tool allows monitoring when each of the spark plugs ignites and to correct whatever needs to be corrected for optimum performance. Whether you want to adjust the spark timing or simply check if it’s properly set, there’s no way around it, you’ll need a good timing light. It’s now common for engines to also have a variable spark timing in an effort to provide the most power and the best fuel efficiency possible. And with technology improving rapidly in recent years, cars are now all equipped with variable valve timing systems. However, for the engine to run optimally, the spark doesn’t only need to happen-it needs to happen at the right time. I found a bunch of other articles with recommendations along the same line too, although most of them weren't coming from official MSD folks.If you work on cars a little, you already know that it’s the spark plugs’ job to light up the air/fuel mixture inside the combustion chambers. In that article, it looks like an official MSD tech support guy is recommending to buy an old-fashioned timing light (a non-electronic one without an advance adjustment). I found this MSD tech support article: Timing Light I've done a little more searching and reading about MSD ignitions and timing lights since last visiting this thread. As you guys know, this thread of action was derailed in a dramatic way by my FE misadventure that Winter. Without the the dial back you are trying to read the little numbers and distinguish between the (rather small usually) marks.Īfter all this time, I'm looking to get my hands on a timing light again.
