I have a 2003 Harley truck. Problem is that when the right turn signal is on I hear the flasher clicking. The right rear turn signal is blinking fast, however I get nothing from the front or the mirror, also the signal is not blinking in the dash,it is not even lighting up. Even if the hazard is on there right arrow still does not come on. The left side works fine. Changed the bulb in the front: however it was not blown. How do you change the Led in the mirror? Any help on what to look for would be greatly appreciated.

 

check all your bulbs front and rear to see if one of them is blown, if not i imagine you might need to replace the LEDs in the mirror

 

with the problem being the front, mirror & instrument panel indicator, I would say the MFS or the MFS connector ( since you have changed the bulb already )

The flasher is fed into the MFS.

When you put the MFS in right turn operation, there are 2 outputs out of the MFS.

1. Feeds the back, this is MFS pin # 5
2. Feeds the front, the instrument panel, and the left mirror turn signal relay ( splice # 246 ). This is MFS pin #2.

The other place could be the connector in the steering wheel column. some times moving the steering wheel to the full up or full down will allow the connector to slide back together.

if this does nothing, time to pull the steering wheel column an take the MFS out, and check the connector in the steering wheel column.

MFS test procedures


I have seen about 50-50 on the problem between MFS and connector, so you will need to check both.

I guess you could pull the 3 screws on the bottom, and check the connector for the turn signal ( with a test light ) on the White w/ light blue stripe wire, before pulling the MFS. Test on the connector side towards the MFS.
This is connector C253, pin #1. C253 is a square 16 pin connector ( 4 rows, 4 columns ).
This is on the connector end, same side as the locking tab.

The truck thinks the bulb is not there, and flashes fast, due to the MFS or C253 problem ( looks just like a blown bulb, no load ).

The mirror light out ( mirror LED or the bulb in the glamor cap ) is not enough of a missing load to cause a fast flash, and if it was a bulb problem only, the instrument panel light would still flash fast.

 

Where exactly is the MFS located?

 

The MFS is your turn signal level stalk.

 

Thanks so much, went out in the garage and moved the wheel up and bam the signals work fine. Gonna get out there and find the loose connection. Once again thanks for all your help, I really do appreciate your help.
