Singles / Fuse ratings
« on: 19 March, 2018, 21:59:57 »
I notice that in my Haynes workshop manual, at the start of chapter 6, Electrical Equipment, the fuse loading is given as "35 amps - all models except the earlier Star series." I'm not sure whether my 1965 B40F is an "earlier Star series" - I guess so. The Haynes book doesn't say what the fuse for them should be. But I was wondering: why 35 amps for some models?  Seems a lot to me. I was thinking of maybe about 15 amps for mine. Obviously I'd need to add up all my wattages before finally working out the rating. But 35 amps seems a lot. Is it because the horn is included perhaps?   Phil (novice)

Thanks and, based on your advice so far, I expect you are dead right. I do wonder a bit why the bike would even start, but I guess if it were a poor connection then it might just start at a good moment. Come to think of it the bike took quite a few kicks before it started.  Thanks again.   Phil (novice)

PS I've ordered the bits for my petrol tank fixing.

Thanks both of you. There's a bit of progress! I had no lights at all, including no tail light or speedo light. So -  thanks for your help - it seemed the problem lay either between the -ve battery terminal and the ammeter, or between the ammeter and T2. My meter showed 6v at the in connection to the ammeter (NU). So the problem would be between there and T2. At the other (out) ammeter connection, where three wires come off the ammeter, there was 0v. But I waggled the connection a little bit, and got 6v and lights! Hurray!  The connection, at a glance, looks okay (see photo), but I guess I need to take the three wires off, and make sure there is a good clean connection. The ammeter now shows -4v when the lights are turned on, so I hope is okay. I guess the problem was either the connection, or an intermittent break in the wire between the ammeter and the light switch (NW)? So anyway I'm chuffed at the moment!  But I still don't get why, at the start of all this, as well as my lights not working, the engine was cutting out immediately the headlight was turned on. Any thoughts please?  Thanks very much.  Phil (novice)

Okay so the answer to my first question is yes? Ie to check voltage at the pilot live connector I can have one probe on the battery +ve terminal, and the other on the pilot live connection but with the bulb and its holder disconnected from the headlamp, ie holding it in my hand?  Phil (novice)

Thanks for this AWJDT. Can I ask a very stupid question: when measuring the voltage between the battery earth connection and the pilot light bulb holder, can I do that with the bulb holder disconnected from the headlamp and the bulb taken out, putting my probe on the contact that the bulb would go against? Or does the circuit have to be in place for me to test it?

By the way, when the bulb holder and its wire are put across the battery, the bulb lights up, so it's not the holder or the bulb. Which is what I expected, as the headlight isn't working either, and I guess the pilot light and the headlight have the same problem.

No, sorry, one between the bolt head and the bracket, and one between the bracket and the spacer?  Phil(novice)

Yes, I take your point, Julian. So looking at AWJDT's 1965 C15 extract, it appears there is a (plain?) washer below the tank bracket, and one just under the bolt head?   Phil (novice)

Thanks AWJDT and Julian. Any comments re the extra washers?

AWJDT's photo of parts, and the explanation of how the arrangement works, seem very clear. But the drawing kindly shown by AWJDT shows a rubber sleeve(41-8020). What is that for?  Also, I notice there are more washers on the drawing than on the photo?  As always, any advice is much appreciated.  Phil (novice)

PS Will spring ever arrive?

I got this and am using it after a fashion, but find it a bit of a pain not to have any crocodile clips - feel I need three hands!  Do all multimeter crocodile clips fit it?  Phil (novice)

Pilot light bulb had blown so I got a new one. Didn't work. Armed with my new multimeter and almost no knowledge, I tested between the live battery terminal and the pilot light connection: about 6v, so I guess okay. Tested continuity of bulb on my resistance (ohms) setting: about 0, so presumably okay. Tested continuity from headlamp hole (where spring clip of pilot light clips in) and battery earth point: about 0, so I guess okay. Across the battery terminals I get a reading of about 6v, so I guess okay. If I press the rear brake pedal, the brake light comes on. So why doesn't the bulb work? Am I missing something blindingly obvious?  Phil (novice)

PS If I am asking too many questions on this forum, please could someone let me know - I won't be offended!

Yes, I think it must be something a previous owner made. I'm going to try to get a proper one.

Thanks. What is the correct length?

Here is the set-up on mine. The rubber was a stiff push fit into the hole (straight hole through tank) and appears to be a rough cut home-made job? I can see that with the orthodox set up the top nut tightens, and squeezes out the rubber, until the nut hits against the top spacer. But with mine it appears to be just tightening onto the rubber?  Anyway, any thoughts on what I've got please?  I'm thinking maybe I need to get it as per AWJDT's.

PS AWJDThumper's photo is much clearer than my fuzzy one - any idea why? Is mine simply short of pixels?
