I recently purchased a very nice 77 gl1000. It runs great but the fuel, temp gauge and cooling fan dont work , fuses are ok is there something common to these 3 things where I might start
Thanks
Mark

Good morning Mark, your fuel & temp gauge is probably the 7 volt regulator gone bad. Go to the store on this forum and look up the hollsco 7 volt regulator. It is a pretty easy installation and they provide easy to follow instructions. it is possible with the temp gauge not working may effect your cooling fan. Someone with more knowledge in this area will jump in to answer your questions. :D :D

The cooling fan is seperate from the gauge circuit.
It is provided 12 volts through a fuse.Its circuit is completed by a temperature switch.It has 2 wires,green is ground.Short the other wire to it and the fan should run(key must be on).
The thermal switch is seen from the right side,center/front engine.theres 2 parts there.one is for the temp gauge,it has one wire on it.

Keep in mind the temp gauge, once it works, needs to be north of normal for the cooling fan to turn on. That is around 220 F so it may not have been that hot.
