CommutaCar Wiring

[Tim Dunning <tdunning@cera.net>]

Hi,
I've been following the CommutaCar discussion avidly since I am (attempting) 
to prepare one for service.  My most serious difficulty is the brakes - the 
wheel cylinders were damaged from long storage and I have not been able to 
find new ones.  There seems to be only one supplier of the rubber parts which 
are quite expensive.  I've honed the cylinders and will see how they work 
when I recieve the new piston seals and cups.  One solution might be to try 
to put new 7" trailer brakes on the car, but that would require custom 
machine work since the existing bolt pattern didn't match the trailer brake 
that I looked at.

I am upgrading the traction power wiring from #1 to 2/0 but noticed that the 
existing  negative pack cable is #2 instead of #1, and is labeled as such on 
the wiring schematic: "#2 SAE 105degrees". The car has an ancient Curtis PMC-
17C controller.  Could the #2 wire be needed to protect the PMC-17 from 
overcurrent?  If so, replacing it could mean replacing the controller down 
the road (if I get that far!)

Thanks for any advice - this a GREAT list!
