Wiring my project

Im almost to that point and Im trying to figure out how many fused circuits i would need. I will be running. The blinkers and tail light are LEDs.

Moty 12 cell battery
starter
headlight
tail light
blinkers
horn

So which circuits can I combine into the same fuse? How many fused circuits should I run?
looking at this but not sure its big enough.
fuse block

Im running a 20amp and a 10amp when it comes to fuses on a stock wire harness. My tail is incandescent and led blinkers.

As a working electrician, I would rather have individual protection for EVERYTHING

Reason being, when your headlight fuse blows, it doesn't take out your ignition, your turn signals and running lights. One fuse may indeed be very simple... but if it blows, you have absolutely nothing. Just my .02 and it's your project. Paul

Beaner242 mentioned the starter. In the stock wiring configuration (at least for the KZ650-C1 - see wiring diagram in link below) the starter is not on a fuse at all, but the solenoid (relay) is in the circuit between the starter and the battery. Question - does that mean the solenoid serves as a fuse if something shorts out in the starter? I've often wondered if there is any protection for that circuit. Ed

Maybe if the starter motor had problems, and pulled excessive amps & caused the solenoid's electrical contacts to stick. This can cause the starter motor to continue to run, even though the energizing circuit is not on. The only way to stop this will be to either disconnect the cable going to the starter motor at the solenoid, or at the Positive battery terminal.

I had this happen many, many years ago on my Honda CB450, I was out for a ride & heard the sound of the starter motor running, I pulled off the road, shut down and the engine started to crank(turn over). I got my tools out, and disconnected the cable to the starter motor, stopping the cranking. Went to the local Honda dealer & ordered a new solenoid. A few day s later it came in & installed it. My 450 had a kick starter, so starting was no problem.

Ok thanks guys. I guess I could run the headlight on 1 circuit the blinkers and tail light on 1 circuit and the horn on another. That would be 3 fuses plus a main inline fuse off the battery?

It's interesting that you mentioned this. I've been looking into installing a voltage regulator from a Ninja 500 onto my 650 & the Ninjas have a main fuse built into the starter relay.

started cutting and reworking things last night. still not positive on how im going to fuse things. i should have ask this before but didnt think of it. what about relays? what items should get one? horn and headlight? i dont think the tail and blinker draw enough to need one right?

Are you going to use the stock horn, or something different? If it's one of the Fiamm horns, use a relay, as it will pull more current(amps), than your horn button can stand.

Automotive 4, and 5 pin relays can carry a lot of current, and are rated at 30 amps and higher.

Just stock horn and actually running it through the old stock start button.

Hello fellas, Its me again. Sop i have a Fuse on the main feed wire that is branched off the the circuits. 25 amp. Here is my question though it has to do with a relay. The start button I ended up using is rated at 10amps. is that big enough or should I run a relay to it. The button is already starting to be hit and miss. I'm afraid im burning it up already. Any ideas anyone?

By rights, the starter button only has to carry enough current to power the "solenoid" not the entire starter motor circuit. You "shouldn't" need another relay... the starter solenoid IS a relay. That being said, if you're having trouble with the switch/push button, it sounds like it's already being over-worked. Just my .02 Paul
