i know it is not the timing light,,i used it on my dads f-350 just minutes before i tryed it on the 7,,now what is the deal,,do you have to have some special timing light??

this is a regular old light,,, one goes on a plug wire and the two power wires go to the battery.

i looked in my shop manual but it was about as descriptive as a blind guy explaining what color your car is.

Should work just fine.. Not that it helps much, but my timing light is a Pep Boyz special and no problems firing.

It's trickey, but most inductive timing lights will fire.&nbsp Move the inductive pick-up along the spark plugs wire - it usually works when the pick-up is closer to the spark plug end.

It's not self powered is it? I've read in a manual somewhere that self powered timing lights won't work on rotaries.

LLADNAR

no it is powered off of the battery

My "deal of the week" timing light from the local auto parts store works fine. Id suggest moving the lead, like Ted said, close to the plug.

Would it make a difference what PLUG he's putting it on? If he's putting it on the trailing, it might not be as effective

Not, really, he should get a reading off any plug, if the light is inductive.

should get a light off any of them, it'll just line up with the different pully marks.

how old are the plugs? worn out ones will not show a light. or if you wires are too thick it might be hard.
