Yup dat's the little p--- pot grinnin atcha...
Soft plastic potting. I use a PC board finger powered drill and dental probes to root around.
Seeing WHERE Mopar mounted the computer and how jittery the voltage is, I wouldn't put it past them to have made the CPU field wire input ultra sensitive. Those boys had pure lard atwix the ears when they got to the CPU voltage regulator fault code design. "Hey Bubba! Gotta idea! Let's made the engine run rough as hell, lose overdrive, and suck gas like an ought-six round went through the gas tank, to lettum know the alternator ain't workin'"
Each brush has it's own terminal. You can reverse the connections and the alternator could care less.
Voltage value variances for the S terminal can be compared to screaming FIRE in the key of G in a crowded theater rather than than the more robust key of A. The reg will work. But you won't get trampled thank goodness. Voltage at the A terminal however is critical. Zatz why the gobbed on silicone grease recommendation.
