Preliminary on Verso page is set with right edge at 7 and 7/8,

and the top (as on the Recto page) at 1/4.

7 — DIAGNOSTICS & TROUBLESHOOTING

SPYGLASS DIAGNOSTICS

The eight-character LCD on the Spyglass displays a continuous sequence of
hourmeter, battery state-of-charge, and fault messages.

Fault messages are displayed using the same codes that are flashed by the

LED. For example, the LED flashes 3,2 for a welded main contactor:

¤¤¤ ¤¤

¤¤¤ ¤¤

¤¤¤ ¤¤

( 3 , 2 )

( 3 , 2 )

( 3 , 2 )

and the corresponding Spyglass message is  

CODE 32
