Diagnose old distributor cap/rotor

Just did a tune-up, replaced cap & rotor... this is what was lurking





I don't know the age/mileage of the one I took off, but that can't be "normal" wear & tear right? I don't want that to happen to the new one I put on!

Here's a bigger pic of the cap -- the center is sort of melted/deformed

The spring wore out and then the contact arced on the rotor creating heat and meltage. The coil is probably still good if it's not melted around the contact point.

if the coil center contact isn't burned, corroded, or otherwise damaged, run it.

I'll have to pull it off & take a look, see if it's damaged at all
