High output alternator recommendations

^^^^^........X2, wiring should be upgraded anytime You up demand, & give it what it needs. Just dumping in a high output alternator can burn-up the wiring even w/o everything running if the battery SOC is too low...& Mopars have the extra bulkhead/ammeter hazard.....research & do as suggested in post #4...
You can't burn-up the voltmeter, only if it overcharges, which can happen if there are poor connections. You should take the voltage close to the batt., fused wire at starter relay B+ post is accurate, it will give You an early heads-up over/under charge.
