3.0 CLUTCH AND/OR TROLL TESTING
The various outputs for controlling the Clutches and Electric
Trolling Valves can be monitored for Open circuits or excessive
current draw by using the
H2(bd) (High Side Driver Fault Detec-
tion) function. However, the applied voltage or current to these
devices cannot be monitored with the H2(bd) function. For this
purpose, the Test Unit can be used. This is especially beneficial
when setting up the amount of current delivered to the Propor-
tional Valve in Electric Trolling systems.
