View source for De-Energize Controller

This describes the universal pre-requisite to all [[:Category:High Voltage Procedure|high-voltage procedures]] on a Zero.

<onlyinclude>
;Overview
: De-energization is a process that is used to disconnect and isolate a system from a source of energy in order to prevent the release of that energy.

;Purpose
: By de-energizing the system, you are eliminating the chance that the system could inadvertently, accidentally or unintentionally cause harm to a person through movement, or the release of heat, light, or sound.

;Tools
: A voltmeter ranged to measure DC voltage beyond the powertrain's normal operating range (0-118V<sub>DC</sub>).
:* Ensure/pre-test that this voltmeter is able to register 0V<sub>DC</sub> as such:
:*# Set the instrument to sense V<sub>DC</sub>.
:*# Touch the sensor leads together.
:*# Verify that it reads 0.0V<sub>DC</sub> immediately with no fluctuations.
:* Test that a low-voltage DC measurement can be registered properly before testing a high-voltage DC system.

;Steps
# Toggle the cutout switch to '''off'''.
# Key off the bike.
#: Remove the key from the ignition lock to prevent re-energizing without ''positive intent''.
# Disconnect external power sources:
#* Disconnect any cable leading to the [[Onboard Charger]] at the bike's inlet.
#* Disconnect whatever is connected to the [[Accessory Charging Port]] at the port end.
#* Disconnect any other power source from the vehicle.
# Verify indications that the bike is not connected to power:
#: The [[Contactor Click Sound]] should have happened shortly after the last power source was disconnected.
#: [[Gen2/Instrument Cluster/Indications#ChargeEnable|Dash charge enable light]] is '''off'''.
#: [[Gen2/Instrument Cluster/Indications#RideEnable|Dash ride enable light]] is '''off'''.
#: The dash is entirely '''off''', really.
# Verify that voltage has dissipated to safe levels (under 12V DC):
## [[Seat Removal|Remove the seat]].
## Before proceeding, ensure that anything on the tester's person cannot make conductive contact with the frame or non-vehicle equipment.
## [[Controller Uncovering|Uncover the controller]].
## Check DC power bus voltage with a properly-rated voltmeter across controller terminals '''B+''' and '''B-'''.
##* Expect voltage to decay exponentially over time.
##* If voltage is not decaying at a sufficient rate, or it plateaus, stop immediately and troubleshoot.
## If, after 10 minutes, voltage is not low enough to consider de-energized, use an appropriately-rated discharge tool.
##: An incandescent light bulb circuit can be sufficient if operated with electrical safety gloves and eye protection.
