If there is no response from any of the following tests, refer
to the main wiring diagram to locate the next connector
in line to ward the con sole and repeat the test at that con-
nec tor. If there is a response at that connector, the problem
may be in the cable between the two connectors (or the
con nec tors themselves).
SPEED INPUT
Turn rotary switch to speed po si tion and dis con nect the
speed sensor (yel low tie) from the main harness. Check
harness speed connector for 12V between pins B (wh)
and C (blk) and 9V between pins A (red) and C (blk).
Using a clip lead or other jumper wire, rap id ly short
to geth er pins A (red) and C (blk) of the 3-pin connector.
See Illustration below.
If working correctly, the console
should show a speed value.
RPM INPUT
Turn rotary switch to RPM and disconnect the RPM
sensor (no color tie) from the main harness. Check
harness RPM connector for 12V be tween pins B (wh)
and C (blk) and 9V between pins A (red) and C (blk).
Using a clip lead or other jumper wire, several times
rapidly short together pins A (red) and C (black) of
the 3-pin connector. If working correctly, the con sole
should show an RPM rate value.

Checking Console Inputs with Multimeter
REMOTE RUN/HOLD INPUT
Disconnect the remote run/hold sensor (or jumper
cover) from the main harness. Check harness remote
run/hold connector for 12V between pins B (wh) and
C (blk) and and 9V between pins A (red) and C (blk).
Placing a clip lead or other jumper wire between pins
A (red) and C (black) of the main harness run/hold
connector (gray tie) should turn off the “HOLD” icon on
the console display. Removing the jumper should turn
on the “HOLD” icon on the console display.
