Hello, 2000 Ultra injection, Cruise not working, fairing rocker lights up, no Tacho light, checked all connections and disconnected the roll off switch, still nothing. if the light in the Tacho had blown would it stop the cruise engaging? Any ideas? thanks

 

Brake light switch.

 

Tried that, thanks both brakes working as they should!

 

I found this in a 1999 - 2005 Twin Cam Service Manual ... maybe it will help


CRUISE CONTROL SYSTEM
DIAGNOSTIC CODES
NOTE
The diagnostic codes can only be
cleared by a Harley-Davidson dealership.
The on-board diagnostic system identifies faults
within the system and stores this information as a
three-digit diagnostic trouble code. The diagnostic
system can store a maximum of eight trouble codes.
Diagnostic codes are displayed as a series of
flashes by the cruise control engagement C light on
the face of tachometer. To retrieve the diagnostic
code(s), perform the following:
1. Turn the engine off.
2. On the front fairing cap, turn the cruise ON/OFF
rocker switch to the OFF position. The light in the
rocker switch is off.
3. On the right side handlebar switch, push the
cruise SET/RESUME switch to SET and hold it.
4. Turn the ignition key switch to IGNITION, but
do not start the engine.
5. On the right side handlebar switch, release the
cruise SET/RESUME switch from the SET position
and look at the cruise control engagement C light.
The light will begin transmitting the diagnostic
codes. Each code consists of three digits.
6. The system flashes the first digit of the stored diagnostic
code. The cruise control engagement C
light illuminates for about 1/4 of a second, then
turns off for about 1/4 of a second. Record the number
of flashes. For example, three flashes indicate
the first digit is three.
7. The system pauses for one second, then flashes
the second digit of the diagnostic code. Record the
number of flashes. For example, five flashes indicate
the second digit is five.
8. The system pauses again for one second, then
flashes the third digit of the diagnostic code. Record
the number of flashes. For example, three flashes
indicate the third digit is three. In this example, the
first code is three hundred fifty three, or an internal
failure.
9. If more than one code is present, the system will
pause for two seconds, then flash the ready signal,
which is a series of six rapid flashes. The system
will flash the other trouble codes after the ready signal.
10. Refer to diagnostic codes in Table 4 to locate
the problem.
11. To exit the diagnostic mode, turn the ignition
key switch to the OFF position.

Thanks, tried that, but still no light on the tacho, think I will check the bulb!

 

Have you tried the speed sensor? It can cause all sorts of things to act up when it goes bad. It will affect the turn signals, the speedo and tach, cruise control etc. Easy fix if that's the problem

 

Everything else works ok, the only other strange thing is the CB seems to always be on Ch19 cant turn it off and when I turn the ignition on it goes straight to CB !! I will look up the speed sensor check, thanks

 

10-4 good buddy .

 

I did ask for it !!

 

I have checked the sensor, all seems to be ok, still no cruise or light!!
