8n trouble

D.H · Jan 30, 2017

1952 ford 8n with side mount dis. 12 volt What should the fire to the plugs be blue,orange or white and what do you do to correct it if its wrong?

Blue, white and purple are signs of a good strong spark. Red, orange and yellow are marginal/weak. Keep in mind if you are setting the gap too long to check for spark it may appear weak, should have good spark color at 1/4" or less gap.

Sorry, the second part of you question on correcting the problem. You need to verify all components of the ignition system, especially the secondary side ( plugs, wires, cap, rotor) are all good. Points need to be good and set right too. If weak spark is noted at the plug or plug wire then move to the coil wire and then coil, if still weak spark then try another coil. Make sure wiring to coil is good though, proper voltage on + side and trigger/ground circuit from --coil side to points/dist too.

Spark should be a blue/white and jump a 1/4 inch gap or more. Points need to be set at 0.025 on that tractor. I also recommend using the HGK3112 spark plugs. I have found they hold up and work better then the auto lite or champ plugs do
