Mini starter crapped out already

Sounds like you got a bad one. Return it. You'd probably have better luck at a junkyard.

I love the Denso in my slant six. Got it at a Mopar swap meet for $35. Put 12 volts to it and it worked so I bought it. Then 2 yrs ago, it just clicked, no spin. Went on line and bought 2 copper contacts for about 10 bucks. Put those in and its good again. Supposedly, that's about all that goes wrong with them.
