Signals electrical issue HELP

[Valor]

I have a 2003 M620 with cheapie aftermarket signals.

On the way into work today, I noticed my right (front and rear) signals were lit up permanently. AND the turn signal indicator on the dash was lit. The turn signal switch was off. Tried flipping the turn signals on and off - still on. Tried turning the bike on and off - still on. Then I flipped the bike off and the right ones went off, but the LEFT ONES went on!

By the time I got to work the plastic housing on two of the signals had melted. Fearing a fire issue, I disconnected all the signals ... The dash indicator stayed lit.

Tried disconnecting power at the battery, hooked it back up and the dash light is still permanently on.

Any ideas??

hmmm. doesn't sound like an issue with the signals themselves.
i would investigate the flasher...

I can't recall if an '03 would have a thermal flasher unit, or an electronic flasher unit built into the dash.
If it's a thermal one, it should be an easy fix...

i'm certainly no expert on the matter, but it's worth a look i think

agreed on not being a signal issue per se....

except how would either flasher get fed with the key off?

[Valor]

Yeah, pretty sure it isn't the signals ... since I have them laying on the garage floor. Hmmm, Where the heck is the flasher unit?

I think that's one of the bikes with the flasher unit in the gauge cluster. I've been wrong before.

Not one of Ducatis better ideas.

Does any of this account for the signals AND the dash light staying lit with the key off and removed?

Could be.

Or it could be a bad key switch, or left hand switch unit.

IIRC Ducati feeds power to the left hand switch and it is distributed to the headlight and signals from there.

My real puzzlement is how is it getting power with the key off?

You need a wiring diagram. Do you have one?

[Valor]

Did a fair share of wiggling, inspecting, etc of the wires. I don't see anything rubbing or burning. I just wired a GPS to the rear tail light wire a month ago. Doesn't seem like that would cause all four signals and the dash light to stay on with the key removed. Drat, I think this might be one for a ride to the dealer.

[corey]

can you disconnect the GPS easily? If so, try removing it and see if anything happens...
just a thought.

wiring gremlins are always a PITA

If your good with wiring I'd wire my own system with 2 relays (left and right). But like I say, if your not up to it, then its a project in itself. That instrument cluster just scares me.

[Valor]

Dealer told me where the signal relays are. Next to the battery. He had me flip them back and forth to see if it changed anything. ... nothing. New thing I learned, if I disconnect the instrument cluster, the lights go out. Might not mean anything. DO you think if I did a Red Key reset it might clear it up?

Your flasher relay is in the instrument cluster.  Disconnect the left hand switch and see what happens with the directionals.  Is the dash doing anything else funny?  Any fogging?

[Valor]

Is there a way for me to reset the ecu, the instruments, or something? Kinda like a reboot of the computer?
