cb550f fuse box/panel on cb350f?
« on: March 25, 2006, 11:48:34 AM »
The wiring on my 74 cb350f was chewed up by the last owner. Does anyone know if the fuse/electrical panel from a 74 550f would work on my 350f?

I was under the assumption that 350Fs had a single fuse holder, while CB550s have the same as the CB750s, a full fuse holder with multiple fuses. I have a harness from a 1974 350F and its a single fuse type. if you want it you can have the harness just pay the shipping. plus 2.00 for my gas.....
CB350 twin vintage road racer, CB350F project, GS750es daily rider, NS400r play bike, 2 MB5s, Z50r project, CB500/590 vintage racer built for friend, CT200 project, and a Gina (Gilera copy made in Argentina)...  And ?????

I ordered a harness already, I just haven’t received it yet but thanks for the offer. On the left side of my 350f, under the cover, there looks to be a fuse that the previous owner spliced into the harness. Now it might be factory but it looks poorly done and in bad condition. If also looks like something is missing. My only reference is a Haynes manual but it’s for both the 350 and 500 and only has one picture and looks nothing like mine.
I know that the last owner removed the starter, the solenoid, bypassed the safety switch, all switches but the light switch are gone, chewed on the wiring, removed both front and rear signals and who knows what else. I bought this to ride and to fix but the manuals that I have are very inaccurate (example is the starter cover shown is clearly for a different model because mine you have to remove the entire side cover for the motor to access and not a small panel as in the book).
I grew up working on older cars and figured a bike would be just as easy but every manual I ever owned was also dead on accurate and the Haynes and loose manual pages I bought just don’t lineup.
Im beginning to think that this does only have the one fuse but again, without a manual to confirm, I turn to you folks for help.

Yeah, I have that bookmarked, I just wasn’t sure if I could trust it, I usually trust Haynes and that didn’t work for this project so I figured id ask some people with first had experience with these bikes. I love riding the thing, faster than I would have thought for only 347cc, I guess it’s the 4 cyl. Thanks for the help, when the harness, starter motor and switches arrive, ill be working on it and im sure ill have more questions.

If you go here you can download the entire parts manual. The workshop manual is also available. The site is Spanish but the manuals are English.

The 350-4 has one 15A fuse. There are 2 wires from the starter solenoid through a connector, the red/white one goes to the rectifier. The red one should have the fuseholder in it, between the solenoid connector and the rest of the wiring harness.
Adapting a multi-fuse block like the later bikes would be a massive headache, you'd be rewiring most of the bike. The various circuits don't branch back to the battery area like on multi-fuse bikes, they just take off from the black wire wherever they are. It would be fairly easy to add a tail-light fuse by the ignition switch  but I doubt if that would be a major improvement.
