TO-DO: finalize lights wiring (gauges + lengths)
22 AWG for all LV systems!!!!
could also use 18 if 22 is too sus…
crimps for 22 AWG available!
to-do: make calculator for wire length, current in - power loss out
make table for harnessing wire lengths
3 solar relays
to begin wiring things beginning of next term
DEADLINE: beginning of next term
Short term items:
clean up mockup spreadsheet
do battery box enclosures
solar harnessing ideas
PD Outputs

Lights
6 turn signal lights (yel”owyellow)
3 in parallel (for either side)
3 brake lights (red)
all in parallel
2 headlights(white)

1 bps fault ubducator (white)
LOCKED ELECTRICAL SYSTEM CENTRAL LOCATION
table for mockup!

can’t be over battery box because they remove from the top
can’t be on side flange since it’s difficult to get to - Michael
figure out area size needed, then reach out to Michael Hanley to figure out proper area for PD

Hardware Board Enclosures review
harnessing sheaths
combine common wires (i.e. GND) and splice them OR keep each wire separate but in common “casings”
FRONT ENCLOSURE TO REAR/BATTERY/CANOPY
run from sides following chassis tubes
REAR/BATTERY TO CANOPY
wiring needs to not restrict opening of canopy
Proposed path: Rear → Front → Rear (on side of canopy) → canopy
REAR/BATTERY TO TAIL
most direct path
UPDATE 28/08/2023: battery box ports will likely be on top of the front of our enclosure and maybe one or so on the lid for the AFEs
TO-DO:
work on PD/BMS portion of MSXV Elec Connections Google Sheet
remember to spec out wire gauges + length estimations!
