Electrical/Wiring Assistance in Houston?

Hey all, Iíve been attempting to chase down an electrical gremlin and could really use some assistance from someone with more skill in that area than me.

The bike: 2007 BMW G650Xchallenge

The issue: turn indicator light on the instrument cluster (dash) remains constantly illuminated, and I do mean constantly...key in any position, key off, key out of the ignition, that light is always on. Clearly this is an issue as the constant draw drains the battery. This is fine at home as the bike stays on a trickle but I have a week long trip coming up in August that will be all off-road with no ability to charge the battery at night. Waking up to a dead bike in the middle of nowhere is just not appealing.

Are there any electrical experts in the Houston area that would be willing to take a look? Iím happy to pay for services rendered, beer or cash Or does someone know a shop they recommend that will do this type of work? My guess is wire not grounding somewhere, chaffed, etc. I just canít trace it.

Thanks!

Re: Electrical/Wiring Assistance in Houston?

does it blink when you turn on either signal? Is there a change in intensity?

I don't know that either of those things matter, but they may. Have you tried simply disconnecting the battery and reconnecting it? That may reset it. I'm not familiar with your bike nor am I any electrical expert. Just trying to think of things that may help.

is this possibly a code thing? fault code gone wrong maybe?

Re: Electrical/Wiring Assistance in Houston?

I'm no wiring expert by any stretch, but I've found that modern vehicles of all sorts will use instrument lights for the craziest warnings.

That said, I'd suggest you try a couple of things: (1) Check all 4 corners of the bike & make sure all your blinker and running lights are working. (2) If it's a cheap replacement, try putting a new flasher in. And NY83 has a good suggestion in (3) disconnecting & reconnecting the battery.

I also did a quicky google & didn't find anything. But you might try doing a deeper dive with the search engine of your choice.

Re: Electrical/Wiring Assistance in Houston?

Thanks guys. I should have clarified a few things:

1: aside from this constant illumination on the dash, everything else is functioning as per normal; blinkers, headlights

2: I have previously completely removed the battery and disconnected and checked all the wiring connections I can find. Reinstalled the battery and ensured all connections and fuses were proper and the problem persists.

As long as there is power running to the dash (key in or out doesnít matter) that light is on.

If you are willing to ride to Sugar land next weekend I could have a look at it . 21 years fire alarm DC tech looking for shorts / grounds / opens in high rise buildings .
Use to make my own classic truck wiring harness , and drag bikes . Many of my friends have had me add all their electrical gadgets on their motorcycles . PM me for a phone # if you like .

Re: Electrical/Wiring Assistance in Houston?

ooo thats a bad problem to have, on that bike. could be the diode relay is bad. they put all the diodes that prevent back feeding in one gizmo.
a leaking electronic flasher could let enough current through to light up the small bulb on the dash, on that bike it is integrated onto the circuit board in the instrument cluster. key off there should not be any power going to it pointing again towards a diode that is leaking current back through system.

I would start by finding location of the diode relay and unplugging it and see what that does.

You might want to cross post to the ADVRider XChallenge Index thread. It's about as good a XChallenge resource as I've found in English.
