Test with timing light

PostAuthor: Quarinteen » Wed Nov 22, 2017 4:49 pm

Saw this post below about testing a cylinder with a timing light. Anyone have instructions with that?

Exactly what do you want to check with the timing light??

You ever get a manual yet? Coarse, I don't know if the later manuals cover this, anymore. As they may have figured since timing is not adjustable, probly just left it out. Don't seem to see anything in the latest Haynes. The earlier Clymers (81-87 XVs) had a blurb in there, bout what to look for. Bout it, though. Either way..wouldn't be tough to just use any 12v light, hooked to #1 coil (hot primary)..turn engine by hand and wait for the light to come on. Then just look thru the timing peep hole and see where the (F) is. Not much you can do about it. Unless ya wanna screw with a C5-ignition.

The OP of the thread ( Loss of power, backfires, running on one cyl.) used a timing light to see if his front cylinder was firing.

Are you asking because you want to know if you're getting current to the plugs, or do you want to use the timing light to check the timing ?
