Sudden Electrical Outage

Recommended Posts

As I was driving home from work last night, all the lights on my 1980 GL 1600 went out. Only the hazards/turn signals continued working. The fuses are all fine in the box but the (15A) headlight ones are not receiving any power (tested via electrical pen). However, when I use the pen to arc from a working fuse to those ones, the headlights work. What should I look for next?

Take a look at the fusible links on the strut tower in the little black box. the black one is the main. There should be a red and a green one, also.

 

The headlights ground thru the switch.

I agree with MilesFox. The fusible link connections are a common place to have bad connections that can cause this kind of trouble. While your checking that it may be a good idea to also clean the battery connections since that is another common place for problems that a lot of people neglect to keep clean.
