View source for Gen2/Fabricate Charger Y-Cable

<onlyinclude>
This describes how to fabricate a Y-Cable for joining chargers into the [[Gen2/Accessory Charging Port|Accessory Charging Port]].
: One can [[Chargers#Combining Chargers|combine]] up to four [[Zero Quick Charger]]s to the 2014+ S platform models (up to 2 chargers prior to 2014).
: To connect more than one charger, at least one Y-Cable is required.
: This cable is [https://www.zeromotorcycles.com/shop/index.php?main_page=product_info&cPath=15_5&products_id=196 available from Zero for $250], but can also be fabricated if you have the tools.

;Steps
# Choose one connector to be the common, to connect to the bike.
#: The other two will connect to the Quick Chargers.
# Using an [[Skills#Power Cables|appropriate crimp tool]], use the #6 AWG connectors to crimp two red #10 wires.
#: Repeat with two black wires.
# Click the #6 connectors into the common SBS75X connector, observing the polarity marked on the connector.
# Crimp the #10 AWG connectors onto the other ends of the red and black wires.
#: Click them into the other SBS75X connectors, again observing polarity.
# Use a #16 - #14 wire for the charge enable pins.
#: Connect one end to a pin-connector, and insert into the recessed hole in the common connector.
# Connect the other end to two socket connectors, and insert into both not-recessed holes in a downstream connector.
#: Stripping back the wire and using heat-shrink tubing may make for a better fit.
# Repeat using the other charge enable pin for the other connector.

;Note
: The seemingly-odd charger enable connections are due to the MBB only being able to drive two Delta-Q chargers per output, and allow a single Y-Cable design to be used as either the first or second in a fan-out.
:;Disclaimer
:: I made my cable the naive way with a single charger-enable pin to both connectors before I was told this.
:: If someone has an official cable and can verify the wiring, that would be appreciated.

This drawing is made from an official cable.

; Charging Two Packs From One Charger
: A simple modification to the Y cable will allow two packs to be connected to one charger.
: This allows simultaneous charging of two packs off the bike.
: While two chargers could do this twice as fast, the AC power circuit for two chargers must be rated greater than 15 amps at 120V, often not available.
:;Disclaimer
:: I believe this modified Y connection is equivalent to the connection used when charging two packs on the bike.
:: So the BMS in each pack controls its charging independently once both are enabled.
:: I have tested it and it works. However, this configuration may be imperfect, use at your own risk.

; Connecting to a Pack Adapter vs Second Charger
: Here is a photo of the modified connector wiring with a pin added to allow connection to a pack adaptor instead of a second charger.
: The added Anderson pin [http://www.mouser.com/ProductDetail/Anderson-Power-Products/879-PM16P1620S30 PM16P1620S30] requires a special insertion tool. However it can be soldered to a heavy wire and supported in place with a tie wrap to the other wires as shown here.
