'74 Dart Sport, 225 with factory electronic ignition & ballast resistor. How hot is normal for the ballast resistor? I turn the key to the run position, and feel it warm up within 30 seconds. After a minute it's almost too hot to touch. Grounding issue? I improved the ICM ground to the inner fender and visually checked all other wiring in the engine compartment and re-tightened ground straps.
I just finished putting the head back on (valve job), replaced a cracked exhaust manifold with a new casting, new water pump, and re-installed everything else that bolts on to these parts. I had a hard time starting it until I bypassed the ballast resistor. It fired right away, ran smooth, and then I noticed the hot ICM & resistor after a short drive. All wiring and grounds were re-installed on the engine exactly as it was before.
Thoughts?
