Trial Coil Wire
The ignition coil wire sits in the ignition distributor of your van and transforms the battery's voltage to the voltage needed to stimulate your Glimmer plugs. The voltage from a battery is by oneself 12 volts. A Glimmer plug needs thousands of volts To possess Sufficiently impulse to turn your engine over. A defective coil wire Testament accumulate your motorcar from starting when you call for it. A meagre tests Testament command you whether the coil is doing its task. On the other hand, you should chalk up some training working with motorcar engines before attempting to deal with a coil wire. Testing the coil wire is an fine road to avoid problems down the means.
Have a second person start the car. Look for a blue spark from the plug. If you receive a nice, bright spark, your coil is fine. No spark indicates a bad coil.
Remove one spark plug using a spark plug socket.
2. Occupation the Glimmer plug with insulated pliers and incorporate it into the coil wire.
3. Lay the solid end of the plug against a piece of exposed metal. This will serve as a ground. An exposed screw or even the negative post on your battery will work fine.

5. Connect your ohmmeter or multimeter to the primary studs of the coil. When you look at the coil, the primary studs will be sticking out the top and look something like two bolts or poles. Enclosed units will have a diagram pointing out the primary studs.
6. Make note of the reading on the ohmmeter. It should be within the range indicated in your service manual. Anything below that number proves a deficient coil.
7. Connect the ohmmeter to the secondary winding. Attach the probes to the outer 12V pole and the center pole.
8. Check to see if the reading is within the specs listed in your service manual for the secondary winding. If not, the coil is bad.
