1977 500 GTL wiring issue

Post by d907ie » Mon May 29, 2017 12:48 pm

I just bought this bike and it has an after market (I believe) regulator. There are 3 wires coming from the alternator, but only 2 are connected to this regulator. The 3rd (red/black) is extended and connected to positive post of battery. Bike is not charging battery, hence my search for the reason. I wanted to see if the alternator was sending enough volts and was looking for connection points (this new regulator doesn't have exposed connectors, only wires coming out). So, I see the red/black wire NOT going to the regulator and thought that was strange. Now I need help. I can't find a wiring diagram, nor any posts to help. Many thanks for any help. peace

Thanks, Steve! I see a couple differences between the diagram and what is in front of me, but I will see how things go while I try and make mine look like the diagram. I will let you know how I fare:-). peace

Steve,

I believe this is an after-market regulator that came from Bevel Heaven. Pictures show 6 wires, where the stock regulator in the diagram shows 4. Only the 2 yellow wires from the alternator are connected to the regulator. The red wire from alternator is connected to the battery...too weird.
