No High Beam Headlight

[sgn]

My 83's previous owner had run a switch to the headlight. In working through some electrical issues I decide to tackle the headlight. I have low beam but when I use the switch for High beam nothing, no light or indicator light.

 

What I have done so far:

 

All connections have been taken apart and cleaned with contact cleaner making sure they are tight.

 

Solder cold joints on CMS (this got the low beam working) and CLASS.

 

Gave the handle bar switch for high beam a shot of cleaner but did not take it apart.

 

Looking at the wiring diagram and reading in the service manual it is looking like I need to check the reserve lighting unit - if I just knew where it was and what I looks like.

 

CMS show no fault codes now so I'm getting closer.

 

Anyone have a clue as to what to check next.

 

The information here on the website has been wonderful in bringing this ride back to life.

 

Thanks All,

Steve

Its up behind the headlight, dead Center, laying horizontally.

 

Best way to get at it, is remove the windshield, and the Plastic cover over the Instrument panel. Its just below that plastic panel,

It has an 8 wire plug on it.

 

There is also another pull apart plug, between the High-Low Switch, and the Reserve lighting unit, Its someplace behing the headlight also. Its a 6 wire plug.

 

Wires for light from H, L Switch thru that plug, are Y/R, L/B , and G , ..

 

Open that plug, and do a Resistance Check thru the Switch. ( make sure contacts in the switch )

 

See page 7-36 block diagram, The Y/G wire From the Reserve light carries power to the Bulb socket.

 

Is the bulb good. ( I know you allready replaced it ) sorry. ( sometimes they Look good, but are not )

Hey Steve, I used to have a spare Reserve light unit if I can find it. Give me a call this weekend.
