See Table 6-1. The drum switch positions and light states with the feed rate dial switch
all the way up are shown below.
Please contact Customer Service for assistance if necessary when troubleshooting the
system using these lights.
S1, S2 - These two red lights indicate the position of the power feed drum switch. Three
possible positions are shown in table below. If the lights are not on or off as shown, the
power feed drum switch is probably miswired or defective.
See Table 6-2. The light states and drum switch positions are shown below.
OUT1 - This red light is on when power is applied to the accessory solenoid. When the
OUT1 is off, the accessory solenoid is not powered. Check the jumper cable connecting
Vkey1 and Vkey2 Terminals. Reconnect if necessary. If the light is still off the accessory
solenoid may be defective.
Vcc - The Vcc light is on when power is applied to the Vkey2 Terminal. If the light is off,
check all connections to the key switch. Also check the fuse located between the Vkey2
terminal and the key switch. Check the 225 Amp fuse in the fuse box. Make sure the bat-
tery connections are correct.
Vcc2 - This red light indicates that power is applied at the control circuits from the key
switch. The light is off when the Vcc light is off. Refer to the Vcc light problems when trou-
bleshooting this light.
Vcc3 - This red light is on indicating the power feed control circuits. The light is off when
the Vcc and Vcc2 are off. Refer to the Vcc light to solve potential problems.
