Title: Electrical Guru's, I have a question please
Post by: bobbyfromnc on February 27, 2019, 08:13:25 AM
I have a 2014 California Touring it has been trouble free for the most part. However recently I have had a electrical situation occur. My turn signals LF, RF, LR all function as intended. However the Right Rear turn signal function has developed the following situation... When brakes are applied either by front brake lever or rear brake lever the turn signal will stop blinking as intended and the solid brake lamp function comes on. Release front or rear brake and turn signal function returns as normal. I have removed the RR light, it does not appear to be cracked in any way, wiring looks good. I followed the wiring to the first disconnect and inspected that connection and all seems well. In my mind the lighting apparatus looks good and solid, running, brake and turn signal functions work with the exception of applying brakes. Is this a relay problem or am I missing something? A new LED right rear lamp is $190.00 I want to see what you guy's think. Thank you, Bobby Kiger

An earth fault somewhere I'd guess

That's as far as I can get though being a Mechanical Engineer  :rolleyes:

Ive had issues like that when a bulb backfeeds. Any two filament bulbs in the circuit?

Lack of current to run both things at once the flasher can is stopping from lack of current, is it LED or incandescent? If incandescent (traditional bulbs) pull the globes and clean the contacts caution WD40 and the like leave an insulating film behind, after that I'd start looking at the earths.

Everyone, a 2014 California is LED.

Thanks rocker59 I guess thats what I get for assuming people would know a 2014 would be LED. Should have included that fact in the post. I'll fix that. BK

Is that system canbus, or is it all separate wiring?

   I would swap indicators with one that you know works to confirm or deny that the indicator is the problem.

As others say it will be an earth problem, current finding it’s way to ground thru the indicator light rather than the earth wire. If you can see a point on the socket connecting to the bulb body run a wire to ground to see if that fixes it, then start tracing the earth wire back to ground and fix it  :smiley:

I agree, it's probably a ground fault (lack of a good ground)
The schematic shows one common ground for left and right but I doubt it's like that

Here is a snip of the rear lights

I'd take those connectors apart and spritz them with DeOxit..  :cool: :smiley:

Great suggestion! Thanks!

Each direction lamp has a dedicated output from the dash. If it's anything like the CARC dash it will include a monitor for
burnt out lamp.

Been not a cruiser type they don't rate very highly in my paying attention to them.

As Kevin says
You might be able to drive a sewing pin through the blue wire between the connector and light (the schematic leads us to believe there's a short wire) then ground the pin.
It could also be a bad connection inside the fitting.
