No headlight, no tail light.

[82Suzie]

Turned on the 1982 GS750E today and no headlight, no tail light.
Replaced fuse but still no headlight or taillight.
I'm thinking that if the headlamp were burned out it wouldn't effect the taillight,
and both high and low beams wouldn't go out at the same time.
The turn signals and brake lights work fine too.
Anyone have an idea of where to look to find the source of this problem?

Dead battery

Battery is at full charge, it starts and runs fine.

Check the on/off switch at the left handle just in case yours still moves like mine does. I would also suggest re-checking the headlight and main fuses then, with the bike off, remove and re-insert each fuse to "reset" them. I have seen instances on my bikes where reseating them will clear the gremlins.

I found the source of the problem.
It was a connector housed in the headlight shell.
One of the six slots had been hot and melted one corner of the plastic.
The lights work now, but I'm watching that piece from now on.

Don't just watch it, ... REPLACE IT.

Vintage Connections likely has that block that melted, the terminals that go in them, a tool to de-pin those terminals, and a great crimp tool to put it back to good as new.

I’ve had great success cleaning all electrical connections with naval jelly, rinsing with water, drying, than a spritz of Deoxit. Dirty, corroded connectors cause resistance/heat that melts the insulation and terminal blocks. On parts that were beyond cleaning, I cut and replaced terminals with ones from Vintage connections.

Like this fuse block connector:


here’s the new one:
