i test out my coils the easy way my girlfriend holds the sparkplug wire in one hand the ground in the other i turn over the moter if she screams it works if she screams and swears at me it works really good-high voltage --no response coil is broken

Free energy technology exists!But the Establishment doesn't want ppl to know this,Go to LT-MAGNET-MOTORdotCOM and get the blueprints for a genuine magnet motor ,Be part of the revolution!

All coils have 2 windings. The low resistance,low "turn" primary winding is connected to the ignition module or points and ground. This winding colapses and induces a magnetic field to the secondary, high resistance, high turn, small wire winding connected to the spark plug and ground. Check between spark plug wire and ground for around 6000 ohms plus or minus 1000 on MOST ignition coils.  Some coils will work until hot and fail. Small wire heats up inside and shorts. Look for cracks.

@Jumpinjacks1 His is set at X1000 and he said it read 6 ohms, he should of said 6000 ohms. You must multiply your reading by the scale you set. Digital meters have the" HIGHEST resistance it can measure" number settings 2000 will not work because you need to measure 6000. Switch up to next scale..20K or 20,000 ohms max. The readings WON"T be EXACT! It'll display 6.00 for 6000 ohms on the 20k setting. but 5.70 or 6.32 is fine also for example. Most DVM's will work fine for this.

hi sir thanks for your vidéo it did help me a lot, one thing i dont know is that i have the exact looking coil you have in your hand the green one does it fit on my 1963 mercury 9.8 model 110. im trying to buy two of them but cant find it.

@SnapDaddy5998 Use a flywheel puller with the appropriate grade 8 bolts.

I have a 1974 20hp Mercury and I want to test the coils. Will this procedure work for testing coils on non-magnito ignition systems?

How do you remove the steel cover that covers the coils underneath the pulley? I have a 51-52 elgin and trying to get to the coils to replace them.
