Electrical System

Diode Circuit Board (Fig. 44)

The diode circuit board contains four diodes and is lo-
cated under the console housing. Diode D1−A provides
logic for the interlock system. Diodes D1−B (right wing
deck), D1−C (front deck), and D1−D (left wing deck) pro-
vide latching circuits for the PTO relay.

Testing

The diodes can be individually tested using a digital
multimeter (ohms setting) and the table to the right. If
any of the diodes are damaged, the diode circuit board
must be replaced.

Apply dielectric grease to circuit board contacts when-
ever the circuit board is installed into the wire harness.
