Hi Paul. to answer: But are you saying you also have/had a bad connection or bad wire at the connection under the gas tank?  Did you find where your connection or wire(s) is/was bad under the tank?  Did I understand you correctly? At first, it did seem like that for some reason, but after I buttoned it all and took it out for a ride yesterday (~20 miles) seems fine! I guess I'll cross that bridge if/when I come to it.

One other thing to note: Ever since I've had this bike, the horn sounded very weak and this gauge was constantly "bouncing" up and down, by tat I mean one dot lights up then two, then three, then back to two etc but in rapid succession (going from 0-10 spastically really. Now it stays on. Maybe that's the way it's supposed to work? I've never had one like this. It's on the halfway mark right up at 12 mostly, whach are red-yellow-yellow-yellow, but once in a great while will flash the green light (over the halfway mark). That light never really stays on but I can see it once in a great while. Before this trouble I never even saw it. Guess I don't know how to read the durned thing.
.

Redux problem: Overall, I had the system working. Now, however, when I drive the left front light only works intermittently (you can see it's actually off in the pic) and the flasher lights range from a steady green flash to a spastic flash. I don't know which they should be. The gauge I've attached here shows the system at a stop when I rev the engine; when I stop revving or am driving, it's minus the green light. Also, when I gun it, hop on the highway etc., the gauge goes bananas for a minute or two, flashing etc. until it goes back.

Other wise, it's working as far as headlamp and horn, so overall I'm good, but I wish I could get the final kinks out

Thanks Mike, I will check that out.

Quick note/observation: While riding I tugged on the harness that goes to the switch on the handlebars, and everything went on. Thinking also to check the connection under the tank (again)>
