Charging System; Current Draw - Key Off - Polaris ACE 900 2017 Service Manual

CHARGING SYSTEM

CURRENT DRAW - KEY OFF

Parasitic draw is when there is excessive current flow
with the key off.
While the most common causes of draws are improperly
installed accessories (tapping into un-switched B +
instead of switched) there can be electronic component
failures that can cause this as well.
CAUTION
Do not connect or disconnect the battery cable, or
ammeter with the engine running. Damage will occur to
electrical components.
CAUTION
Charging system damage will occur if incompatible
components are installed. Always reference Polaris
Electric Parts Catalog for proper part numbers.
NOTICE
Wait ten minutes with the key off for the ECU to power
down. This will avoid a faulty readout while testing
amperage draw.
TESTING PROCEDURE
1. Remove the negative cable from the battery.
2. Connect a jumper from the negative battery cable
terminal to the negative battery post.
3. Ensure your meter leads and selector dial are set to
measure amperage.
4. Connect your red lead to the battery negative cable
terminal.
5. Connect your black lead to the battery negative post.
11.34
6. Momentarily key the ignition switch on, then off.
CAUTION
Ensure all electrical components are switched off, or
damage to your jumper and/or meter will occur.
7. Wait 10 minutes before checking the value. Vehicles
will vary, but electronic components will take time to
fully go to sleep after switched power is removed.
8. Maximum allowable is 10 milliamps. If your meter is
ranged to the 10 Amp scale, this will appear as 0.010
Amps.
Current Draw - Key Off:
Maximum of .01 DCA (10 mA)
9. If over 10 milliamps, go to the fuse block and start
systematically removing one fuse at a time until the
value drops, indicating the circuit that requires
attention.
