Product Details

12V 20A 6-Terminal Shunt Regulator-Rectifier — Replaces 21066-7011 Direct aftermarket shunt-type voltage regulator-rectifier​ for Kawasaki FH/FR/FS/FX commercial V-twins. Replaces Kawasaki 21066-7011, 210667011, 21066-0740, 21066-7001, 21066-7003, 21066-7006, aftermarket Stens 435-194, Arrowhead ESP series. Specs: 12V DC, setpoint 13.8-14.4V, 15A continuous / 20A peak, 6-terminal plug-and-play (2× AC stator in + B+ + EAR/ground + 2 control), cast aluminum heatsink + epoxy seal, ~82×46×22mm, ~0.13kg. Match old stamp 21066-7011​ before order.
For Kawasaki FH/FR/FS/FX Commercial Engines & Zero-Turn Mowers Engineered for FH381V through FH921V, FR541V/FR651V/FR691V/FR730V, FS481V through FS730V, FX481V through FX1000V​ on 12V electric-start. Covers Toro TimeCutter/Commercial, Hustler Raptor/Super Z, Spartan RZ/RT Pro, Gravely, Snapper commercial, portable generators​ with Kawasaki power.
Fixes No-Charge, Overcharge & Hard-Start Resolves regulator faults: battery reads <13V at full throttle (no charge), >15V (overcharge boils cells), headlight flickers with RPM, stator overheats, weak spark hard-start. Shunt transistor shorts open (overcharge) or fails closed (no charge). New unit restores 14V setpoint. Test old: at 3600 RPM red/black to ground should read 13.8-14.4V; outside range = dead regulator.
2-Hole Bolt to Blower Housing, 6-Terminal Plug-and-Play Disconnect negative battery, locate regulator on blower housing/shroud, remove 2 mount screws, unplug 6-pin connector, mount new unit to same holes, torque to 35 in-lb for heat transfer, plug in 6-terminal harness. Critical:​ this is a 6-terminal plug-in unit​ — if your old regulator has 2 yellow + 1 red wires (B&S style) or 3 terminals (Kohler style), you have a different regulator and this SKU will not fit.
Confirm 6-Terminal + 21066-7011 Stamp + Kawasaki Commercial V-Twin This regulator has 6-pin plug, cast aluminum body, 21066-7011 stamp, and fits Kawasaki FH/FR/FS/FX commercial V-twins with 12V 6-terminal charging. Before ordering, photo old regulator and confirm (1) 6-terminal plug, (2) Kawasaki engine, (3) 21066-7011 or 21066-0740 stamp. Applications outside this scope (motorcycle, Jet Ski, automotive, B&S 2Y+1R, Kohler 3-terminal) use different regulator numbers and are not covered.
