Speedometer
The speedometer can be tested using a DC pulse gen-
erator.
CAUTION
Make sure the voltage source is turned OFF be-
fore connecting it to the electrical circuit toavoid
electrical shock and prevent damaging the
gauge.
1. Connect speedometer to the pulse generator and
DC voltage source (Fig. 43).
2. Take test point readings.
A. Set generator to 325.2 Hertz. Apply signal to
circuit. The needle s hould point to 4MPH.
B. Set generator to 650.4 Hertz. Apply signal to cir-
cuit. The needle should point to 8MPH.
C. Set generator to 975.6 Hertz. Apply signal to cir-
cuit. The needle should point to 12 MPH.
3. Turn off the voltage source. Disconnect voltage
source, gauge, and variable resistance.

Reels Enable/Disable Switches
The reels enable/disable switches are attached to the
instrument panel. The RM 6500-D and the RM 6700-D
has one switch that controls cutting units #1 through 5.
TheRM6700-Dhastwoadditionalswitches,oneforcut-
ting unit #6, and one for cutting unit #7 (Fig. 44).
The switch that controls cutting units #1 through 5 is a
three position switch. Positioning the toggle back closes
the switch between the back (brown wire) and center
(black wire) terminals. Positioning the toggle forward
closes the switch between the front (orange wire) and
center terminals.
OntheRM 6700-D,each oftheadditional switchesused
tocontrolcutting unit#6or #7aredual positionswitches.
Positioning the toggle back closes the switch between
eitherthe white (#6) or violet (#7) wire and the black wire
terminals.
These switches can be tested using the “Input Checks”
feature of the ACE Diagnostic tool.
