Chrysler electronic ignition tester.....

This is the coolest thing I picked up at the swap meet. Some fellow, non Mopar guy, walks up to me and asks if I like Dodges. I guess do to the Moparfest shirt, he had a good idea I did! Anyway he tells me he has some "Dodge stuff" and doesn't know anything about it. He just acquired it with some parts he got one time. He showed me this and it had a $10 sticker on it. Needless to say, it became mine instantly! Don't know if it works or is useful or not, but it's cool nonetheless! :D
