Continued from first posts in Hi from Northern Ireland.

So I put the battery on charge just to have something to try until I get a new one delivered. Whole bike was still completely dead. No lights / indicators / horn, not even any idiot lights, and definitely not a peep out of the starter. I checked the main fuse which looked a bit blackened but not actually blown, but I replaced it anyhow. Still nothing. Then I noticed when I put the headlight on, the headlight itself  didn’t come on but the oil pressure light did. Tried the starter with the headlight (not) on and it cranked over reasonably well for a while, but definitely not sounding like it had any intention of firing up. Didn’t have a plug spanner so tried to check for a spark with an old nail stuck in the plug lead and nothing at all. By this time the battery had pretty much expired again. So I took the headlight out to have a look and there’s 4 wires hanging out going nowhere. Then I took the tank off and there’s 4 more wires there going nowhere too. Part of the problem with this is I’m colourblind, so trying to identify wires just from the colour involves quite a lot of guess work! One of the tricks I’ve always used is to wrap a bit of masking tape round a wire and then just write on it what it is. I noticed that a few of the wires under the tank already had masking tape on them with the colour written on (but not what the wire actually is.) So looks like there’s already been another colourblind would be electrician working on the bike and who knows what wires are connected up right or wrong! Going to have to sit down with a wiring diagram and a test meter and a lot of patience to get my head around this! On the plus side, wiring doesn’t look like it’s been bodged around as such, maybe just wires connected up wrong, or not connected up at all, so hopefully once I can identify what wires go where that might solve the problem..

Hi all, new to the forum, but not entirely new to these old Hondas, had a few of them over the years although I'm by no means any kind of an expert so will be looking help and advice on this '76 550F which I just got a couple of days ago.

It's in very nice condition but I've actually taken a bit of a punt on it as a non runner. Most recent mot certificate that came with the bike was 1997. It was then restored at some point after that by the seller's father, and seems to have been recently only used for vintage displays at NW200 and such like. Seller reckoned it needs a new alternator / rectifier and probably the carbs cleaned etc. The battery is completely flat so as bought there's no life in it at all. It looks nice though...
I'll start another thread for work ongoing to try and get it running, so any advice much appreciated, cheers, Pete.
