A. Wiring
All small wire leads are routed through plastic flexible conduit which protects them and makes a neat
easily removable and replaceable wiring harness arrangement. This wiring method allows the replace-
ment of a single wire lead with a minimum of difficulty. All wires are color coded.

Provisions have been made to allow removal of the generator exciter without disturbing or removing
the complete generator.

• The four 1/4" bolts on top of the panel.
