Chrysler DVA (Peak reading) and Resistance charts

Performing tests on ignition components requires that you have the proper equipment to do so. This chart assumes you have the adequate testing equipment to diagnose ignition problems

Understanding this chart:
Example: Grn = Green   Wht/Grn = White/Green Stripe
"Wire to wire" means take measurement between those colors of wires on the component
Light green columns are reference readings for measured ohms of the specified component
Light yellow columns are reference readings for measured DVA output of specified component
While it's possible a component can be within specs and still be faulty, any component found not to be within specs should be replaced.
