Light Issue

Woe unto you that bought the first model year of a major remake, perhaps this section can help address any 2014 and later model Ural "imperfections". Here's a special section for folks with the latest rigs to discuss 2014 and later model-related topics such fuel injection, 3-wheel disc brakes, hydraulic steering dampers, spin-on oil filters and other anomalies that don't belong on true Russsian motorcycle ;-P We've gone from using big hammers and greasy wrenches to needing computers and Ouija boards in order to fix our rigs.
Forum rules
Please keep this section specific to issues pertaining to 2014 and later models such as fuel injection, sidecar and rear disc brakes and so forth. Ask general or non-2014 and later specific questions in the main Hammerin' & Wrenchin' section.

Light Issue

Post by HassoBoxhead » Wed May 01, 2019 4:41 am

I was riding on the way to the Pentagon for work at 0-dark-thirty this morning when out the the blue every light on the bike went out. Only the brake lights worked when pressed. What do I do to rectify that?

Only difference lately electrically was that I put the Auxbeam LED headlight a couple weeks ago.

Appreciate any help on this!!

Trace the wiring diagram and find a common link. Hotflash44 is probably correct - Ck fuse then look for an exposed wire that’s shorting.

The ignition switch was the cause on mine when I experienced a smiler outage.

Here is a link to the 2014 wiring diagram.

https://static1.squarespace.com/static/ ... iagram.pdf

Fuse 6 is for all the lights except the brake lights. It is the one with the yellow wire coming off of it.

One word of caution, it is possible your fuse box is mounted upside down from the way it is shown in the wiring diagram. There are a number of 2014's out there like this.

Just a heads-up. The wiring harness is barely capable of handling stock amperage. Just in case you have to delve into that. Don't ask how I know.

On the 2014 GU that I am refurbishing ("restoring" sounds pretentious), I found a melted wire in the harness that sourced headlamp power. For reasons unfathomable to me, there are no relays in the headlamp circuit this year (and presumably others). This machine is totally stock; no headlamp or other power-drawing modifications had been made to it. The design has the headlamp pulling 5 amperes or more through what appears to be an 18 gauge wire. Not good.

I am of course adding headlamp relays.

Thank you all for the information! I'll start with the fuse panel tonight when I get home and go from there. Will let you know what transpires.

This is one reason why I added a headlamp relay to mine, so it gets the juice direct from battery. (The second reason was so I could also add a switch to turn the headlight off.)

That's only the "side" lights, fuse 5 (gray wire) does ALL the lights including the headlight. But to confuse matters, power for the side lights goes thru the fusebox twice, fuse 5 and then again thru 6, only so that it can still be fused (#6) when the ignition is in park position. For this and other similar reasons there can be a lot of resistance in the harness causing Voltage drops at the actual bulbs.

Ok, I replaced all the fuses, turned on power, worked fine for 5 seconds,then cut out again.

As I said... my money is on an exposed wire. Also, remove/disconnect the headlight you installed. That should narrow your search.

Yep definitely a short somewhere. Presume it's fuse #5 that fails?
