wiring

I am currently building a cafe racer out of a 1972 cb350 twin. And I run all LED lights and a a Ricks Rectifier and Regulator hooked up. As of right now I making a wiring harness. I would like to run a main wire direct to the battery to the Ignition switch and then to my fuse box so everything...

Where to start, I guess you'll probably need to know what bike this post refers to... 1978 CB400T HawkII -TLDR at bottom- Bought it as a project a couple years ago, with little to no experience and expectations through the roof. Since then I've got it to start and idle, although not...

Bought this bike awhile back with a seized engine. Swapped it out with and engine out of a cl but swapped the rotor and stator our of the cb. I’m lost on how to hook up all the engine wires. Sorry new to vintage motorcycles.

I've got a cb400t here that is all fully restored and ready to hit the road and just the other day I noticed that the brake wires that attach to the handbrake (front brake) got stripped out of the casing that they were in. When I got the bike it was already wired up to the handlebars so I didn't...

I recently dumped all my wiring into a bucket under the seat.... or what I could get into it. Everything works and runs except the brake light. Mystery. It worked up till the mod. I traced the green/yellow and black wire to the brake swtich/spring to their proper mates in the main harness but...

Okay, The brake light works normally, but the tail light only comes on when the ignition key is all the way to the right. the attached pic shows two open wires (unconnected) running to the rear end, I don't know if that would have something to do with it. everything else electrical seems to...

I am replacing the switch with an aftermarket switch. The current switch has 8 wires. There is a Blue, White, Brown, Yellow, White/Yellow, Black/White, and 2 black wires. Here is what I know... The Blue wire is the high beam and the White wire is the low beam to the headlight. The Brown is...

New to the forum, hope you guys can help me out. I searched the forum, but no luck. So I'm trying to help a friend with his project. It's a custom trike with a '92 CB250 Nighthawk engine. The wiring is just hacked up bits and pieces, and I need help getting it wired to run. I have a wiring...

i'm trying to figure out what i'm wiring what to what for this 3 toggle switch and a new halogen headlight. i know my white and blue are my low and high. they go directly to the 'on' prongs on the toggle i believe (correct me if im wrong pleaase) green...where does green go? and the 'off'...

Greetings Honda people! As promised in my introduction this will be my first project for my 85 rebel--fixing the wiring the PO so graciously dismembered for me! So lets start with the spaghetti left by this meatball: Mama Mia! All I wanted to do was remove the electronic speedo/tach that he...

I was going to set the point timing today when I noticed something odd. The left point is connected to a yellow wire and the right point is connected to a blue wire. In every diagram I've seen of the ignition coils it's just the opposite - the left coil connects with a blue wire and the right...

Hello, so i was having sparking issues on the left side and noticed the leads were fried so i replaced both coils with new caps and spark plugs. The weird thing is that after i installed them they were both giving spark and that was awesome, but when I went back the next day to go for a ride, I...

I am having a problem with the ignition section of the wiring. Bike is an SL350 k-2, new points, condensor, and coils. When testing for power in the order of connecting the wiring power to coil is good, connections to coil/condensor is good, but when connecting the two point wires one side...

Completed an install of new headlight and front turn signals after removing an aftermarket fairing from PO. This is a 1979 CM 400a for my wife; first project was to clean up the carburetor with new gaskets, jets, etc. With that done I moved on to the fairing and lights but ran into a spiderweb...

Hey guys, so after a fiasco with those EMGO universal handlebar switches, I decided to go back to the stock Honda ones that originally came on the bike when I purchased it. I know they work, (or did before I replaced them in my build). I replaced the stock bars with clipons, (black anodized)...

Hello everybody! I've been doing a load of research on my problem but haven't been able to figure it out, so I made an account to ask for help! A little backstory - I bought this bike nearly 2 years ago and it ran (rough but still ran). I didn't even ride it before I started tearing it apart...

Hi there, After struggling to understand the stock wiring diagram to reduce the wiring mess for my CB400T Cafe Racer project I came up with my own diagram: Blue blocks are switches, yellow are lights and grey are devices. They are disposed similar to the real places on my bike. I hope you...

Hi all, I am building a 69 CL450 K2 and the wiring on it is really rough. There are some after market harnesses on eBay for a CB450 K0. Could I modify it to fit my bike? Should I build my own? I'm new to motorcycles and the forum. Any and all help is appreciated. Thanks! Ryan

First off, this is a first for me both to the form and also posting to one. I'm at my wits end trying to figure out this signal issue on my 1972 Honda 350f. I've had this bike for close to 10 years now and had to fix a number of things on this bike. Problem is that I've never been too good...

Recently got my CB450 back from the mechanic, and he mentioned that the tail light wiring was wacky. I discovered the taillight and the low beam headlight don’t work (However the brake light, turn signals and high beam DO work) I’ve attached a photo to see if anyone can spot something obvious...
