Can a 12 Volt Spark be a no spark?
If you get 12 volts, the points are not conducting when closed, if you get 0 volts, you are not getting any voltage to the coil or the points are not opening. As for the 12 volt spark, no, if everything was right, you would get about a 250 volt spark. When you have current flowing through the coil, a magnetic field builds up around the coil.
What to do when your engine has no spark?
Insert a spark plug tester into the plug boot and ground it on a piece of metal on the engine. Finally, Have someone crank the engine and watch for spark. Remove one of the coils from the spark plug. Use an extra spark plug. A spark plug tester. Or even a screwdriver in the end of the coil.
Why is there no spark in my ignition?
An ignition module requires some type of external input in order to activate. If your vehicle stalls unexpectedly during operation and will not start again, it is likely because of loose or corroded electrical connections in the ignition module. In this case, check the switch, clean oxidized terminals, and replace broken wires if necessary.
What should I do if my no spark light is not flashing?
If you see the light flashing then things are OK with the points and you need to check the rotor and the coil high tension lead to the disty for a problem along with the coil itself. If the light doesn’t flash then disconnect the minus lead and verify power is getting to that point on the coil.

What should I do if my spark plug doesn’t work?
Leave the Hi-tension lead out of the cap. With ignition On, turn the pulley by hand (or have someone crank the engine). The tester should go On and Off twice each revolution. If it does that, you should get spark. If the tester stays ON while cranking, the points are not closing.
What should I do if my GY6 coil has no spark?
If there is still no spark, the coil is likely bad. Check for proper plug gap! The plug is very rarely the cause of no spark on the GY6. If the plug is fouled or cracked it may not spark. Ensure that the spark plug is gapped properly.Recommended spark plug gap: 0.6mm ~ 0.7mm (0.23″ ~ 0.27″) Was this guide helpful?

What happens when there is no spark from the ignition coil?
1 Power. Two positions of the ignition switch provide power to the positive primary post of the ignition coil. 2 Signal. With no external signal to the coil negative primary post, voltage would travel through the ignition coil windings without inducing any secondary spark. 3 Flow. 4 Open Circuits.
How to troubleshoot a no spark car engine?
I am grateful for the help. First, check for 6 volts between the negative terminal of the coil and ground while the engine is cranking. If you get 12 volts, the points are not conducting when closed, if you get 0 volts, you are not getting any voltage to the coil or the points are not opening.
What does a pigtail on a vacuum advance mean?
(There is no pigtail on distributors which have no vacuum advance.) Points shorted (stuck closed). Condensor shorted. Coil open. Take the Green points wire off the coil terminal. If the tester now goes ON , either the points or the condensor is shorted.
