Question about 1989 Dodge D150
I am helping a friend get his 1989 Dodge Ram D50 pickup running. Someone told him to replace the coil. He did, but I'm not sure he wired it right. Do you have a wiring diagram for that? I think it has a bad control module in the distributor, but before I drop a hundred bucks on it I'd like to ensure that the coil is wired correctly.
Check the resistance on the coil. the (+) (-) side should be about 10 Ohms resistance and the part that goes out of the coil should be 1-2 ohms resistance. Get yourself an ohmmeter and check it. best way to check is to figure out what wire runs from the computer to the coil and follow the wiring all the way to the coil making sure theres no rips or shorts. If there isnt, then I would splice into the two wires and run two new wires over to the coil. If it still doesnt have spark then its a faulty computer and should be replaced. Good luck
