Topic: CB550 Wiring help

[streak09]

Hey Guys!

Getting ready to wire up my 550. Im going with minimal wiring to get her started up. I made the attached diagram and would appreciate any tips or corrections that should be made. I have the Electrosport ESR240 regulator/rectifier and a Shorai battery.


Im not very experienced with electrical, so any help you guys can provide so I dont fry anything would be great!

Did this wiring setup work out for you? I'm trying to do some very minimal basic wiring with a cb400f and an es240 i just picked up.

No fuses?  No lighting? too basic.

Funny that this topic has Come back to life, I just asked the same question in my build thread!

Ill give a quick update and maybe I will partially answer your question Rexall.

I decided to go with the pamco system so the wiring slightly changed and I cleaned it up a bit.

I was able to get spark and not fry any wiring with this set-up with no fuse. This was just by turning the engine over a few times. At the time I also did not have the rectifier/regulator wired up to make sure I didn't fry it.



Right now the bike sits exactly as the wire diagram shows, with exception of the fuse. I need some input on where I should place it and what amperage I should use. Right now I am going without lights, I will add that circuit later once I know the bike runs and charges correctly. RB550four, do you have any suggestions?

I would not run an automotive electrical system without one. It will also not interfere with diagnosis of proper charging, that is an incorrect assumption on your part.

I did not mean to imply that I would run the system with no fuses, I absolutely understand that they are needed. I also understand that it does not affect the functionality of the system. What I meant was I didn't test my ignition system with my regulator/rectifier wired up because I did not have a fuse to protect it.

So, given the system I showed earlier, what needs protected the most? I would say the battery and regulator/rectifier?

Now, what I struggle with is where to place the fuse to protect that component, and how to determine the correct amperage fuse. In order to protect a specific component (lets say the battery), do I place a fuse on the + lead of the battery?

What about the regulator/rectifier? Do I place it at the + power lead coming into the unit?

This is the type help im looking for. Thanks!

The fuse is only going to prevent your battery from melting and your bike from getting on fire. As a matter of fact if the fuse blows it's likely because something in the circuit is shorting, including R/R.

You can run a single fuse like is shown on your second diagram, that looks fine. Fuse like that should be 15A. If you want something fancy then you can use lower amps on lights and ignition. I don't, it's very unlikely the headlight is going to straight out short, the taillight is LEDs, blinkers have on-off switch and you have to run a killswitch.

Thanks Maurice! That helps. So if I did want to put a fuse on my lights circuit, would I put it my + wire providing the power to the system?

Yes plus side is where you put fuses, easier to separate circuits.
