I really am not good with electrical. Any ideas of where to start looking if my turn signals work but my hazards don't?
Looking at the wiring diagram, it has a common ground with your TS so if they are working right I would say dirty contact in the switch as a first guess.. All the switch is doing is feeding a ground to the ACM to trigger the hazards... Im out after you clean and check that as the next stop using my limited electric background is the ACM causing the problem.
Here are the self diagnostic procedures.. While there is NOT one for faulty hazard, it is checking the system and it does call for using the hazard to cancel the test so this would test the switch itself by default. Im hoping this helps you troubleshoot...

AUTO CANCEL TURN SIGNAL SYSTEM
SELF-DIAGNOSTICS
The auto cancel module (located under the console)
contains a self-diagnostic feature. The self-diagnostics
can be activated to run a test of the turn signal circuits,
turn signal switch (left handlebar switch), and the autocancel
module power supply.
To enter the diagnostic mode:
1. Turn ignition key OFF.
2. Turn hazard switch ON.
3. Turn ignition key ON.
4. Pull and release the front brake lever (or rear brake
pedal) 3 times within a 3 second period to enable the
diagnostic mode.
? All 4 turn signal bulbs will illuminate for 1 second
and then go out, to indicate the diagnostic mode has
been enabled. (Only bulbs in working order will
illuminate)
? The ?blink codes? now start flashing on the rear turn
signal bulbs.
Notes about the blink codes:
? Refer to the chart on page page 19.14 for a list of
codes and what they mean.
? Code 12 will always be present; alone if there are
no faults in the system, or with other codes following
if there is a fault. Code 12 marks the beginning of the
code display sequence.
? There is a 2 second pause between blinked codes.
? Each code will blink twice before the next code is
displayed. Example: If a code 13 is present, the
indicator lamp will flash code 12 (1 long pulse, then 2
short), then repeat the code 12, then code 13, and
repeat code 13.
? The blink codes will flash until cancelled by turning
the key OFF or by turning the hazard switch OFF.
Turning the hazard switch OFF before turning the key
OFF will change the diagnostic mode to the next
level, which is ?Turn Signal Switch? diagnostic mode.
Turn Signal Switch Mode:
5. Perform Steps 1-4 to enter the diagnostic mode.
6. When codes are blinking on rear turn signals, turn the
hazard switch OFF. The system will finish the code
display sequence then enter the Turn Signal Switch
diagnostic mode.
Turn Signal Switch Tests:
7. Move the turn signal switch to the LEFT TURN
position and HOLD. Both left turn signal lamps should
light.
8. Move the turn signal switch to the RIGHT TURN
position and HOLD. Both right turn signal lamps
should light.
9. Push the switch in to the CANCEL position. All 4 turn
signal lamps should light, indicating the cancel switch
is working properly.
BLINK CODES
NOTE: Fault codes (13 and above) will only appear when actually present. A separate ?code clearing? operation is not required.
When a problem is corrected, the code will not be displayed when the sequence repeats.
CODE Code Description / Possible Cause Diagnostic Steps
12 Self Check Complete Normal - always displayed as first code
13 Left Hand Circuit Over-Current
Possible Causes:
Shorted bulb (filament has shorted across filament
posts) Action: replace bulb.
Short to ground at socket or in related wiring. System
will interrupt power to the shorted circuit. Left side
bulbs will not be illuminated.
Action: Determine front or rear. Inspect wiring.
To determine if front or rear left signal circuit is at fault: 1) Remove
seat. 2) Disconnect rear wire harness 8-pin connector. 3) If code
13 is no longer displayed, cause of overcurrent is in rear left signal
unit or circuit. If code 13 remains, fault is in front left signal unit or
circuit. IMPORTANT: The system will now detect undercurrent
due to the open rear connector, and display code 14 and code 16.
These codes will disappear after rear harness is re-connected.
14 Left Hand Circuit Under Current (Open Bulb, No
Bulb, faulty connection, etc.)
Inspect / replace bulb; inspect socket or connections to bulb that
is not lit.
15 Right Hand Circuit Over-Current
Possible Causes:
Shorted bulb (filament has shorted across filament
posts) Action: replace bulb.
Short to ground at socket or in related wiring. System
will interrupt power to the shorted circuit. Right side
bulbs will not be illuminated.
Action: Determine front or rear. Inspect wiring.
To determine if front or rear right signal circuit is at fault: 1)
Remove seat. 2) Disconnect rear wire harness 8-pin connector.
3) If code 15 is no longer displayed, cause of overcurrent is in rear
right signal unit or circuit. If code 15 remains, fault is in front right
signal unit or circuit. IMPORTANT: The system will now detect
undercurrent due to the open rear connector, and display codes
14 and 16. These codes will disappear after rear harness is reconnected.
16 Right Hand Circuit Under Current (Open Bulb, No
Bulb, faulty connection, etc.)
Inspect / replace bulb; inspect socket or connections to bulb that
is not lit.
17 Low Module Voltage Check for battery voltage to module (Pin 9, Violet)
(Must be >12 VDC)
