Diode Assembly (Greensmaster 3420)

The Greensmaster 3420 wire harness contains a diode
that is used for circuit protection from voltage spikes
when the engine starter solenoid is de--energized. The
diode plugs into the wire harness in the engine area (see
Greensmaster 3420 Wire Harness Drawing in Chapter
10 -- Foldout Drawings).
Diode Test
The diode (Fig. 90) can be individually tested using a
