The whole idea behind adapting a larger alternator is to provide a bunch more amperage when demand is high. This means that in addition to the alternator, a larger charge wire that connects the alternator to the battery is necessary. Generally, a 6-gauge charge wire is necessary to handle more than 100. A good test of resistance is to measure the voltage at the alternator output terminal with the engine running. Then measure voltage at the battery. If the voltage difference is less than 0.50 volt, then the charging wire is a sufficient size. If the voltage drops more than that 0.50-volt number, the charge wire is too small and needs to be upgraded.
