Let’s define the features of these regulators to better understand the functions of the alternators:

A. Stator activation – this function allows the alternator to cut-in at the right time and start producing the required power to charge the battery. Please note that this function is not available through other aftermarket suppliers of electronics; hence a late cut-in of the alternator / undercharge of the battery is evidenced.

B. Short circuit protected – Transpo products are designed to fully protect the regulator from field short circuit conditions of alternator.

C. Under and Over voltage detector – The warning light turns on when the voltage regulator detects a low or high battery voltage conditions.
