You cannot test it with a diagram. You will need a multimeter to test the coil. Click the link.
there is nothing to test a coil is just a peice of metal rapped in circles
If the reason you want to check the coils is because of a check engine misfire code swap the coil with a coil from another cylinder, clear the codes, drive if the check engine light comes back on see if the code follows the coil you moved. If so replace the coil.
Take a test light connect it to a good ground and find the wire that has 12volts or "lights up" the test light ONLY when turning the key to the full start position and will not light on accessory or run.
Take off the modual and coil pack take it to autozone they will test it free.
HOW DO YOU TEST THE COIL PACK ON A 1995 MERCURY MYSTIQUE DOHC 6 CYL.
does the coil pack make it run better
Here's how i tested the COIL ON a DODGE RAM and it should apply to any coil . you need an Alligator clip ok, you clip that into the plug end of the coil harness , NOT THE COIL ON THIS MACHINE IT doesn't matter if it is live or ground. TAKE A TEST LIGHT clip the ground of the test light onto the alligator clip OK , NOW TOUCH THE OTHER SIDE OF THE HARNESS. GET A HELPER TO TURN THE KEY OVER IF THE TEST LIGHT STAYS SOLID RED OR GREEN THE COIL IS A PASS GREAT OK RUN. IF IT FLASHES LIKE A TIMING LIGHT THE COIL IS shot . I RECALL THE COMPUTER WILL MEMORIZE THAT THE COIL IS GONE AND IT WILL FLASH THE TEST LIGHT TELLING YOU I AM SHOT.
