Lincoln "L" Technical Questions

Voltage Across Coil
Craig DeVine

We're measuring 1.2 V across the (+) and (-) terminals of the coils, while running. Using an analog meter.


Is this voltage high enough? We've heard it should be 4 or more V.


Thanks for input...

If the engine is running well, you have no problem. How dose it run under a load, like climbing a hill in high gear. t engine pulls well, you don't have a problem To confirm, check point gaps - should .020"

Using an analog voltmeter to measure a high frequency chopped DC voltage will give a reading including the mass inertia of the meter hand and its actuating coil, it might read higher.

With the engine stopped, you get a higher oi==point-to point voltage at one coulld see a higher reading nearly 5V if that coil, points are closed. There are times when both sets can be closed..

Confusing?

Thanks so much for the quick reply. I'm Craig's partner in this car. Your guess is right...Trouble climbing a 18% hill even in 1st gear. New plugs gaped to 020. Voltage with engine off and points closed is 5.

I am manually advancing timing by sound and feel because the Centrifugal advance is not working. That being said,

the car climbed the same hill last year ok.

Should I try to measure Amps?

oops Plugs 025



points 020
