When I'm out and about, I get an awful lot of questions about testing ignition systems, especially how do I see all my cylinders at once on one screen?
We're going to do that today with this thing behind me called the SIA 2000.
This was designed to work on waste-spark systems and I have this hooked up to a 2001 Taurus which is a waste-spark car, so one coil fires two cylinders at once. This can also be used with flag pickups, use coil on cap adapter, coil on plug adapter, all sorts of different ways to do it.
I already have it hooked up to the scope so once we load in to the lab scope module, I'm going to go into Ignition Scope and I'm going to start off in a parade pattern. Let's fire up the car and see what we get for a pattern.
Let's pause that after a few seconds and that's looking pretty good here. Across the top, this yellow line, that is the side that's firing spark at the time, and then the green line is the waste-spark side. So that's the side that's firing on the exhaust stroke.
We've got a pretty good pattern here. We've got good spark lines across all of them, they all look pretty even, so this car, looks like it's doing pretty well.
You can also look at it in a raster pattern, they call it, so you can see all of them right on top of each other. You can compare cylinder to cylinder to see how they're firing.
And we could also look at it super-imposed over each other so you can take a look and see how they're firing in relation to each other.
There's many uses and lots of quick, easy ways to check your ignition system.
