(ET) location of circuit breaker 1

[Chris Zach <czach computer org>]

Quick question: In the wiring diagrams for the E-15 and E-20 there is a 
circuit breaker called "CB-1" which goes between the PTO positive and 
the positive for the motor at the contactors.

Where is this? CB-2 is the one on the firewall (45amps) and CB-3 is the 
one in the E20 motor. But where/what is CB-1?
