Battery condition is extremely important. No voltage regulator can work correctly with a bad or weak battery. Always fully charge your battery before performing any charging system tests or replacing parts. If there is any doubt, have the battery load tested or replaced.
There are two possible regulators for the IQ Widetrak, Pro RMK, RMK, Rush, Rush Pro, Switchback, Switchback Adventure and RMK Asssault 600 and 800 cc from 2011 to 2014. This regulator is a 3-phase, 20 amp regulator and has 6 wires. The other regulator is a AC/DC, 14.3V regulator with 3 wires. That regulator is part RM30913. Always check in the 'Fits models' section and please compare to your original part before buying.
