Think about it this way: all the circuits on your bike need an uninterrupted path from + to - (ground) to work*. Following that path will help you understand what's going on and is also a valuable diagnostic tool. Check out the stickies IronMick linked.

Safety note - it's better to wire things with the longest path on the + side. In the case of the start button, that would be + -> start button -> start relay -> ground. This way if the wires short out, it pops the breaker instead of trying to turn on the starter! Also, the key switch should always be between your circuit and the battery, otherwise you have no way to de-energize the circuit. Bad day if your start button is always live and you bump it when the bike is parked.

As I mentioned earlier, you also always want to take your + connection from a circuit breaker or fuse. So for the start button you'd connect it to your IGN breaker. If you have a kill switch it gets a little more complicated, but think about what the kill switch does and you'll see where it needs to go. The full path would be + -> MAIN breaker -> key switch -> IGN breaker -> kill switch** -> start switch -> starter relay -> ground.

The indicator lamps get + on one side from the ACC breaker, so the other side needs to go to ground. In the case of the oil lamp that's through the pressure sender in the pump.

Hopefully this all makes sense and didn't get too far into the weeds.

*This is a simplification, but I find it helpful since we're only dealing with DC and the wires are mostly on the positive side of the circuits.

**The kill switch being before the start button is important. Trace the power flow and you'll see that with the key on, one side of the kill switch is connected straight to +. Then if the kill switch is off, neither side of the start button is connected to +. Much less likely for a failure to turn the starter on that way.

If you had the kill switch after the start button, one side of the start button is connected to + and you're relying on the kill switch to keep the other side locked out - greater potential for a bad day. If it helps, think about it like a lamp with the switch in the neutral line instead of the hot. You can turn the lamp off, but if you stick your finger in the socket it'll still zap you.

Thanks for the response brother.. whats got me stumped right now is my compufire dual ignition light won’t turn on I can’t time the bike. The little magnet and light: flipping the magnet over and spinning the timing plate.. still can’t get a light. I’m on TDC. I followed compufire instructions all the way up to the light. I tested it w the battery yes. Any ideas? Thanks

Which compufire do you have, the HD or HDE? I skimmed the instructions, and the HD is timed at the front cylinder advance mark, but the HDE is timed at front cylinder TDC.

I would also strongly suggest checking your flywheel timing marks against the actual piston position, because you might not have the "correct" flywheels for your year. Some of the members here have learned this the hard (read: expensive) way.

It looks like the “HD” although it’s marked HD-1. But I’ve seen the HDE it’s newer and looks different. It’s not that. This is exactly the answer I’ve needed thank you a thousand times over... the diagram says to ground the black wire to the coil and attach the red the positive side ignition coil.
I have both marks on my flywheel. It WAS at TDC.. it’s now at the advanced mark. How could I tell if I have an S&S motor? Just curious. I’m going to try and fire this thing up. Only way to see right? Thanks again for all the help my friend. I’m still referencing all your information

S&S flywheels have a number stamped on them visible through the timing hole.it will be upside down when it comes up.

So I have 2 final issues..
My carb is not squirting fuel and I think the starter pinion is stuck? As you can see in the videos:

The carb I think Is simple fix. I'll work on it. Something looks backwards lol... But the starter is making a horrible sound. First thing I thought was the starter gear was stuck or something?... ideas?

Pinion gear only turns one direction. If it spins both ways. Fubar.

I see no videos.

Video sounds like weak battery or loose connections with relay or solenoid.

That push button end starter motor plate that is sold would be a god send in trouble shooting this.

New battery. Bike starts and runs. If it’s not one thing it’s another. I am beyond over this bullshit. My spirit to even want to ride anymore is gone. I’m bored. I wired the whole damn thing even. Pathetic.
No matter how many times I check the carb accelerator pump or take off the stupid fvcking Spring... doesn’t matter. It won’t squirt fuel. With fuel in the float, adjusted, pet cock on, fuel has gravity, I don’t know. I’d say I’d save myself the headache but I’m beyond that. Taking it to a shop to finish. I give up. Thanks for the help.
