Cornering lights

Postby iamwill » Mon Apr 02, 2012 11:16 am



How about this for weird, I have an intermittent issue with the gl1200 limited cutting off like its losing spark or gas not sure. But the other day when I started it up the yellow running lights on the fairing sides were not on instead the cornering lights were, the fuel light was coming on while running in this condition and would cut off shortly thereafter. I fiddled with the main harness connections in the faux tank and it sorted itself out. Does anyone understand how that could happen? I do not. I rode it about 35 miles each way there was not so much as a stutter. I took it to about 20 miles away and it wanted to act up after sitting for about 15 minutes it ran good for another 10 miles then same thing cutting off. After 30 mins it took me the rest of the way home. But the cornering lights were not on. I just think it is weird how they could be on instead of the running markers on the fairing.

Virtually every time you have electrical problems that can't be easily explained, where lights that shouldn't be on are on, and lights that should be on aren't, you've got a bad ground somewhere. Because the ground is bad, it instead finds a ground somewhere else, and more often than not, that's through a light bulb somewhere, which lights the bulb up.

Makes sense but why would the orange running lights not be on in your opinion? possibly from channeling the ground to the next point that has a good one ? Wow and I am an electrician so I feel I should know this stuff but electronics are different.

Grounding errors like this can take forever to track down... days !! Weeks !!
I would borrow a signal injector circuit tracer from a electrical friend ( a device that puts a high frequency onto a 12 volt signal, so you can trace it )


Then , starting with the known problems ( Running markers, cornering lights ) track each circuit back to its ground connection, and clean it up.
Its gonna take awhile !!

A coloured wiring diagram ( like a Clymers ) is useful to trace and find where the connections are.

The other possibility is also in the harness, a cross talk short of some sort.... especially since shaking it seemed to cure it .

On my 25 yo machine, I found that my braided copper ground strap was a " Science " experiment : green , and white powder... so you might start with that ...
Its just forward of the battery, starter area, but on the inside of the frame .

Also,on my 1200 interstate,the wiring go through a large multi-conductor plug.Some of the connectors were corroded.I ended up having to cut the wires off the plug and replacing the connector on those 2 wires.I had intermittent turn signals.

That grounding thing makes perfectly good sense I will methodically locate and correct as many grounds as I can locate. I currently have this bike up for sale and hope I do not sale it crazy huh? But in the mean time I will keep on trying to learn all I can about it.
