The only way to see is with the wiring diagram. Check the fuses and fuse clips for corrosion. These type of glass fuses can fail internally and look good. The only good way is to pull them one at a time and with the multimeter or self powered continuity light see if the fuse is electriclly good.

Disconnect the positive battery lead, put the new test light between the positive battey terminal and the positive battery cable and turn on the ignition but do not start the bike. The light will burn out if the starter is used.
If there is a short the light will come on. Disconnect the circuits one at a time to find out where the short is. any place the harness is flexed or rubs the frame is suspect causing the fuse(s) to blow.

Nope, they can't do that. The running lights are wired from an accesory terminal bus line off the ignition switch.kztee wrote:

Any glass tube fuse more than a couple of years old needs to be chucked and replaced.Get a multimeter so continuity and voltage checks can be performed. The taillight circuit may be seperate from the instrument bulb circuit.
The only way to see is with the wiring diagram. Check the fuses and fuse clips for corrosion. These type of glass fuses can fail internally and look good. The only good way is to pull them one at a time and with the multimeter or self powered continuity light see if the fuse is electriclly good.

Make up a 12 volt light with some small alligator clips and wire(Radio Shack stuff) and put it in circuit where the fuse goes. If the light comes on you have a short.
radio Shack also sells a cheap 12V buzzer you can use for troublehooting like this so you don't have to keep watching for the light.

I am also having that same problem on my 80 750 ltd. Everything else is OK besides tail light and gauges don't light up
