Main Wiring Harness for Armstrong MT500. 84720267SR. Qty 1. All kick start Rotax powered motorcycles.
MT500 WIRING HARNESS (84720267SR) FITTING GUIDE
This main wiring harness is designed to replace the OEM version on the Armstrong MT500. It is compatible with the OEM ignition switch and console wiring harness. It is literally plug and play.
In addition to the OEM version there is a further 2 way connector. It is marked ACCS. This is switched live for the Low Voltage Switch 84621010SR when used with 3ph Regulator 999 064. If not using the Low Voltage Switch it can be used to activate a relay for heated grips or spot lights etc. We do not recommend using this connector to power accessories directly.
Each wiring harness has been tested prior to leaving the workshop. If you are having difficulties or experiencing the same faults as your old wiring harness you may have another electrical fault.
Always ensure the grey earth wires are correctly attached to the frame of the motorcycle and the battery is also correctly attached to the frame.
This wiring harness is designed to work with the following regulators:
CEV OEM REGULATOR 84720093
If the standard issued regulator is still fitted you must connect the green jumper lead (supplied) to the green phase from the generator and then connect the ring terminal to earth inside the air box.
1. Orange 2. Empty 3. Grey 4. Thin Red 5. Purple 6. Thick Red 7. White
3 PHASE REGULATOR 999 064
This regulator will use all 3 phases from the Rotax generator. This will provide more power for eg. Heated grips, spot lights, phone charge point without discharging the battery and making the lights dimmer. It is fitted under the seat.
If you wish the generator light on the dashboard to function you will also need Low Voltage Switch 84621010SR.
Fitting instructions are supplied with both items.
3 PHASE REGULATOR 84723378
This regulator also uses all 3 phases from the Rotax generator. Fitting instructions are supplied with this item.
It is fitted underneath the headlight.
