Fuses

The following chart lists the possible causes of blown
controller fuses F1, F2, and F3. If a fuse blows, replace it

and resume operation. If the fuse blows again, use
Figure 5-17 to identify the faulty component(s).

Inoperative audio/visual alarm

Blown F1 fuse (remote annunciator: 3 amp)

Blown F2 fuse (controller: 3 amp)

Battery connections reversed

Shorted DC supply to indicator panel

Shorted controller circuit board

Blown F3 fuse (engine and accessories: 15 amp)

Inoperative engine electrical components

Inoperative overvoltage board

Inoperative panel lamps, engine gauges

Inoperative dry contact kit

Remaining accessories connected to TB1-42A
