Regulator, Good or Bad? And what’s this?

[71SandbugCharger]

Is there a way to tell if a voltage regulator is good? I want to get a rev-n-nator, so if good, would I get much from this one if it is good even? And... what is this other electrical thing I got in my box of goodies?

Thanks!
I found the ECU is a Mopar Performance Orange Ignition Control Unit P4120505 - about $46 in Summit or Jegs, or anywhere else.
The voltage regulator is a Wells/Ampco VR733 - about $24 on ebay.

No idea if they work or are good, or anything. Guess I will stick them on the sale pages for just the cost of mailing if anyone wants them.
