I'll tell you how I have timed my vehicles for years and it works like a charm with no light.

You need 2 people for this. 1 in the drivers seat, this person does a "brake torque" the driver seat person sets up to do a burnout. But DO NOT break the rear tires loose. Just load it up as much as you can without turning the tires or moving the vehicle. Just try to keep the revs and torque fairly stable.

While doing this person 2 moves the distributor, move it back and forth until you feel the vehicle producing the most power. At this point stop and lock it down. Sometimes this will be a little too far advanced. Drive the vehicle after this until it is good and warmed up. If you notice no ping, that is good. Shut it off, start it up. If you notice no starter drag then you are good to go. If you experience any ping or starter drag when warm the retard the timing a wee bit. Do this until the ping/or starter drag are gone. Presto you are timed to what your engine likes.

This method is for vehicles that do not have computer controlled ignition timing.
