Speedometer; Reel Enable/Disable Switches - Toro Reelmaster 6500-D Service Manual

Speedometer

The speedometer can be tested using a DC pulse gen-
erator.
Make sure the voltage source is turned OFF be-
fore connecting it to the electrical circuit to avoid
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 should point to 4 MPH.
B. Set generator to 650.4 Hertz. Apply signal to cir-
cuit. The needle should point to 8 MPH.
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.
The RM 6700-D has two additional switches, one for cut-
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.
On the RM 6700-D, each of the additional switches used
to control cutting unit #6 or #7 are dual position switches.
Positioning the toggle back closes the switch between
either the 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.
