Instrument Voltage Limiter / Regulator

This unique limiter replaces the limiter style that plugs into a circuit board on the back of your dash. If you don’t have a circuit board, then you may need the #RT-IVR3 style limiter, or you may have a dash that has the limiter built into the fuel gauge (ie 1965 Dart and 1967-69 Barracuda's). Also, it is extremely important that you make sure that you have the proper size fuse in the fuse box for the instrument cluster. In most cases the proper sized fuse 5A or less. The limiter is designed so that if there is any overvoltage from the alternator, then the protection circuit inside the limiter will blow the instrument panel fuse, alerting you to the problem and protecting the limiter and gauges from faults. If the fuse is too large, then the fuse won’t open up and the limiter will be damaged in an overvoltage situation
