Does a 1987 dodge ram 100 have a ballast resistor? If so, where?

Where is ballast resistor on 97 dodge ram 1500 pick up Google Search .see if this link helps you out

William, your car uses a ballast resistor that causes what you describe. This is usually a ceramic white, rectangular piece, mounted on the firewall.
The voltage to the coil has to be dropped to 8 volts, or so. Chrysler handles that with a ballast resistor and it fails.
To test, you can wire across the resistor and see if you have spark.
My recollection is one side is for the coil and one side for the wipers or something like that.

This is a common problem.

Ballast resistors were used to reduce voltage across the contact points after start so the points didn't 'burn' so quickly. As there are no points in your engine, there is no ballast resistor.

You must be living in the 1960's

Ballast resistors were for ignition with points,
to reduce the coil voltage to under 10 Volts

there should be a white ballast resistor in the circuit to cut the amperage back on the coil.
Check or replace ballast resistor sometimes they was mounted on firewall next to the ignition module either a 2 prong or 4 prong white ballast resistor.

Check the ballast resistor mounted on the fire wall. It's white about 3 inches long with one screw in the middle. Use a test light and check to see if you are getting fire across both terminals. If not replace it. Fire comes from the ignition through the starter relay to the ballast resistor and then the coil. Hope this will help you.

WHAT PROBLEM ARE YOU HAVING?THERE ARE
NO BALLAST RESISTORS ON DODGE PRODUCTS ANYMORE

shouldnt matter

it is a pick up module in the distributer then to the coil!
