After tearing down everything to the front fairing in order to replace the R. handlebar electrical pod, and re--installing everything, the turn signals/emergency flashers do not work. The lights work, but when the switch is signal is activated, it turns the light off. Any ideas where to begin?

Did you unplug the flasher relay? Depending on the year of your bike, it is either a circuit board in the rear of the gauge assembly or it is plugged into the harness and hanging in behind the gauge assembly.

It is an '03. I will check the flasher relay. On my '03, is the relay accessible with only the meter panel off, or is more disassembly required? Thanks.

The 03 has the circuit board in the gauge assembly. Is everything else on the bike working? The power for the turn signals powers a few other things, so if they are working it's not a power problem. I doubt you unplugged it in the rear of the cluster. Check all of the plugs under the right and left fairing pockets.

Everything else works. There is one connector for which I can't find the other end under the left fairing pocket. The connector is maroon with 2 wires in a rubber boot that also includes the white connector for the audio wire that comes up into the pocket. Nothing else seems to be unplugged under either fairing pocket.

When you turn on the hazards do you get anything? Did you remove the gauge cluster when doing this repair?

Well I would have to look at the schematic of that, but just at the moment I suspect a pinched wire , shunts power to ground when you activate the switch.

The little maroon (red) connector you found is a aux power connector, does not connect to the bike circuits.

Thanks Techdude and Kit. There is no wire pinched insofar as I can view with the fairing pockets and mirrors removed. I guess it will be a matter of complete dismantling down to the front fairing removal to check for a pinched wire.

Despite the satisfaction derived from repairing/maintaining your own ride.....I am now at the point of not buying such complicated equipment w/o a warranty. My trip leaving this morning for Seattle is off.

Sorry about your trip getting cancelled. Here is a picture of the relay's harness connector(3P at the bottom):



Another connector you should check is C24 under the right side pocket. The turn signal switch and hazard switch wiring both run thru it:

Repair postponed for a couple weeks

Many thanks to both of you! The trip to Seattle will proceed, just not on the GL. When I return in a couple weeks, I'll dive right into it. In the mean time, tools are put away, bike is parked and covered and I will persevere upon my return.

Well, I began again on the journey to solve this issue....to no avail. checked all the plugs, relays, fuses, looked for pinched wires, even took it over to Don at Wing-Nut in Fairfield for a quick look. He said to bring it back when he can have a couple hours at it and he'll solve it.

I did learn how well put together all the plastic bits are on this machine. Everything fits together precisely with a tightness that shows how well it is made. In the meantime, it bettered me, and I'll let a pro look it. Thanks again for your suggestions.

If all of those plugs looked good, then the flasher relay itself is possibly dead. The gauge assembly has to come out to check it. Goodluck.
