ELECTRIC CAR PROJECT 9311 DIARY, FEB 97
---------------------------------------------------------------------
2/7/97
The charger booster and new 50-150 voltmeter arrived. Four
battery
mats arrived.
2/8/97
Determined the changes that have to be made to the front
accessory
mounting plate. The charger booster will mount where the charger
was
and the charger will be moved to the left. Drilled the new holes
and
mounted the charger booster. Drilled a hole in the charger
booster's
case and installed a grommet. Routed the wires from the interlock
relay through this grommet. Will require an 8-1/2" by
7" "porch" on
left side of the mounting plate to support the charger in its new
location. Lost a 1/4" flat washer in the front compartment.
Replaced
the state-of-charge gauge with the 50-150 voltmeter and
reinstalled
in the car.
2/11/97
Picked up the finished battery rack at Industrial Plating. Picked
up
two cut-to-size aluminum pieces for the accessory mounting plate
porch at Alaskan Copper and Brass.
2/12/97
Cut thin plastic sheets (aka For Sale signs from the hardware
store)
and battery mats to size.
2/13/97
Installed the engine compartment battery rack. Determined the
final
routing of the power cables and secured to the rack with cable
ties
as planned. Applied weather strip tape to inside of the battery
holddown. Drilled the holes in the porch pieces and the accessory
mounting plate. The porch attaches to the accessory mounting
plate
with a 3" by 7" backer plate using #10 flat-head
screws. Installed
a 1/4" rivet-nut in the car under the mounting hole in the
porch.
2/14/97
Took porch pieces to Industrial Plating to be black anodized.
2/15/97
Drilled an additional mounting hole between the charger booster
and
the charger in the mounting plate and installed a matching rivet
nut
in the car. Installed a 2-pin connector on the battery wires
going
to the charger. Applied vinyl tape over the drain slots on the
ends
of the batteries. Removed the engine compartment lid. Used the
crane
and the battery puller to install the batteries. Connected the
power
cables. Did not interconnect the two batteries. Reinstalled the
lid.
The holddown is too flexible and does not work will. Will
redesign
and make a new one. Wired the charger booster to the charger.
Wired
the charger output to a 2-pin connector and to test points.
2/16/97
Cut pieces for new holddown. Drilled holes. The cross pieces will
be
attached with 1/4" flat-head cap screws rather than welded.
The new
holddown weighs about 2 pounds more than the old one. Made a
jumper
out of 1/16" thick by 1" wide copper strap to
interconnect the two
batteries. The jumper is rectangular, about 4" long by
1-1/4" wide
with a 5/8" gap in one long side side, so as to be flexible
to allow
the batteries to move around a bit.
2/28/97
Picked up porch pieces from Industrial Plating and dropped off
the
new holddown pieces to be powder coated.
