Just noticed i have no headlight (high or low beam) and no lights on my gauges. Everything else is fine and all the fuses in my t/c fusebox are fine. any particular place i should check first?

Had the same problem this week . I wasn't as lucky my head light rely was the problem. Having extra parts hanging around can be helpful

Headlight relay is most likely the culprit. Relpaced mine with a standard bosch relay.'78 E "Stormbringer"

40 amp on the switched side is a typical capacity rating for most bosch style relays, as the current draw from the low beam filament is under 6 amps (55w /12v) plus the dash illumination lamps, and only slightly higher on high beam, it is more than adequate.Originally posted by vanquisher51 View Post'78 E "Stormbringer"

Had the same problem today on a 79F, I did the RLU bypass and headlights are back. Relay had already been bypassed.Originally posted by kevxs View Post2H7 (79) owned since '89

the connections behind the headlight all look pretty clean, i cleaned them up a bit anyway although I need a clever method for leaning the female connections. I think the RLU is right near the ballast resistor under the tank but where do I find this 'relay'?

On my 81 SH, the headlight relay is directly above the coils right up near the neck of the frame. It is a square metal box inb a rubber strap with a sleeve on top that mounts to the frame. Look right bove the coils, should be fairly easy to see when you know what your looking for and where to look.Life is what happens while your planning everything else!
When your work speaks for itself, don't interrupt.

The RLU is a black plastic box held in with 2 phillips screws atop the left side of the frame by the voltage regulator. It says reserve lighting device on it or somthing similar. To bypass it, unplug and in the harness plug, jump the pins that go to blu/blk and blu/yel wires. Headlight relay bypass is jump red/yel and blu/blk wires in the harness plug.2H7 (79) owned since '89

bypassed RLU and Relay, still no dash or headlights
so i spliced together the blue, black and red, yellow wires on the headlight relay and also the blue/yellow, blue/black wires on the RLU and still my headlights and dash lights dont work.
when the problem starting happening, it was intermittent. some days i'd start the bike and they'd work sometimes not.
connections in the headlight enclosure looked pretty good and have also been cleaned.
can anyone help?1979 XS1100SF 37000km

At the headlight relay, you only need to splice the red/yellow and blue/black wires together. Leave the other two disconnected and insulate the ends.Fast, Cheap, Reliable... Pick any two
