1989-1996 Dodge Dakota Trucks Ignition Coil Tests

The ignition coil for the vehicles covered by this guide is in the following locations:
• 1989-92 engines: mounted to the firewall
• 1993-96 2.5L engines: mounted on the thermostat housing in front of the coolant temperature sensor
• 1993-96 V6 and V8 LDC engines: mounted to a bracket bolted to the right engine cylinder head
• 1993-96 5.9L HDC engines: mounted to a bracket bolted to the air injection pump (AIR pump) mounting bracket.
1. Inspect the ignition coil for arcing while the engine is running. If the engine will not start, this can be performed while the engine is cranked by either an assistant or a remote starter. Look at the coil in dim or low light to aid visibility of any arcing. 2. Arcing at the tower will carbonize the wire boot, which, if it is connected to a new ignition coil, will cause the coil to fail. In such cases, clean all the carbonization away or replace the components as necessary. 3. Using a coil tester or ohmmeter according to the manufacturer's instructions, test the primary and secondary resistance. Replace any coil that does not meet the specifications indicated in the accompanying chart. 4. Inspect the secondary coil wire for any sign of damage. Replace if any damage is found. Carbon tracking on the old wire can cause arcing and the failure of a new ignition coil.
