Title: Fuse board, 1976 550F1.
Post by: fogrider on May 04, 2021, 07:33:54 PM
Still sorting the wiring, wired the ignition plug as the photo's I was sent , does'nt seem to like that, no side lights or clock bulbs. .  There is a diagram in the Haynes manual which shows a different layout, may have to (carefully) try that. In the meantime, checking for current flow raises the problem that it has a 5 way fuse board and all the diagrams I have found all show only a 3 way. Current, with all off, is live on 4th from the left. No such thing on my diagrams !
Is there a diagram showing the 5 way ?.
Regards all.
Terry.

Two of the five are just spare fuses. That's why you will not find them wired in the diagram. The three that are wired, are a 15A main, a 5A taillight and a 7A headlight fuse. The spare fuses sit at the left and the right position, 1 and 5 if you like, in the box.
BTW, here you will find the CB550F Owner's Manual that has all the correct wire diagrams: http://www.honda4fun.com/materiale-documentazione-tecnica/libretti-uso-a-manutenzione

Ah, 1 and 5 the spares, that's what's thrown me, I assumed it was 1234 live and 5 spare.
I'm getting closer . The indicator problems were the earths on the rear lamp brackets - ally rivets corroded stopping the connection.
Front stop light wires missing, rear stop switch U/S, no bulb holder for the front side lamp, talk about neglect !

Soon be on the road.....

Thanks for the info
