Steel yourself for a sadly too high odds of ******* the ECU off and having it render the whole program into limp home mode (check engine light). MoPar crafted an ECU menu that compares field voltage to battery voltage and if one of the two differentials exceeds a pre-determimed point, the ECU takes its ball and goes home.
It won't damage anything. But it may disappoint. Not even a dummy ballast an artificial field load will "outsmart" the ECU. A volt gauge warning would have been too easy. An alternator failure demands gross pollution and a 20% loss of economy and top gear.
More dope-smoking engineering hard at work.
