== DC ELECTRIC POWER MANAGEMENT ====
. Power Circuits Overview. All loads on the AXYS sleds are powered by DC power.
1. DC System Power (orange) 16V supports Fuel Injectors, Ignition Coils, ECU / regulated to 5V for Sensors. Dedicated magneto stator coils feed this circuit thru orange leads.
2. DC Engine Power (red) 14.5V supports Exhaust Valve Solenoid & Gauge Relay Coil (600), Exhaust Valve Actuator & Relay & PWM Convertor & Capacitor Relay (800), Electronic Oil Pump, Fuel Pump, Instrument Cluster MFD/IDD. Dedicated magneto stator coils feed this circuit thru black leads.
3. DC Chassis power (red/white) 14.5V supports Pass. Warmers, Low Headlights, Taillights, 2amp. fuse to Brakelights, 2amp. fuse to hood 12v (cig. lighter) outlet. Dedicated magneto stator coils feed this circuit thru yellow leads.
Thru Load Shed Relay (red/blue): Handlebar & Thumb Warmers, High Beam Headlights, RCA (faceshield) accessory connector and thru Battery Charge Relay: recharge of battery.
4. Battery (red) 12V DC Powers Electric Start solenoid and Starter motor. Goes thru a 20amp. auto-resetting circuit breaker (red/black) and Powers Electric Start Solenoid receives battery charge thru charging relay, also feeds 2amp. Constant Power fuse (gray/red) powers ignition key to IDD gauge when KEY ON or START.

DC power management turns off/disconnects some loads under certain circumstances. The priority is to make sure the 800HO VES electronic Smart Actuator, the oil pump, the fuel pump, the low beam Headlight and brake/tail lamps have sufficient power.
The ECU will turn ON the LOAD SHED RELAY (red/blue), when:
1. Engine Speed is in excess of 2200 RPM.
The Load Shed Relay is Open or OFF, when the engine is not running, and when the engine starts.
After Initial engine startup, it is recommended to allow the idle to stabilize and then apply throttle to bring RPM above the 2200 RPM load shedding threshold. (This will get power to the handlebar hand/thumb warmers & high beam headlights).
You can then release the throttle, and so long as the idle stays above 1400 RPM (MY15) / 1500 RPM (MY16up), with 11 volts D.C. or higher, the load shed relay will stay ON.
The ECU will turn OFF the high beam headlights, handlebar hand/thumb warmers and battery relay power, via the LOAD SHED RELAY, when either one of these conditions occur:
1. Engine Speed less than 1400 RPM (MY15) / 1500 RPM (MY16up). Normal idle after break-in is 1700 RPM
_ OR
2. DC Voltage on the Chassis Circuit is less than 11 Volts D.C.

The BATTERY CHARGE RELAY will open and not charge the battery, when either one of these conditions occur:
1. Engine Speed less than 2500 RPM
_ OR
2. DC Voltage on the Chassis circuit is less than 13 Volts D.C.
Otherwise, if the engine is running, the BATTERY CHARGE RELAY will be closed and charge the battery.
