Bicycle generator on a Seagull - example shown

[atoyot]

I came across the listing of a stolen Seagull here on this website, and while I can't help to recover it I did find the addition of a bicycle alternator ("generator") to the arrangement quite interesting.

Would the owner, or anyone else who was bold enough to try such a thing, please comment upon the life that one received from that kind of hookup? I'm just dopey enough to try to put a 12-volt alternator onto a 40+ just to say i tried it.

Warning That picture sent my anti virus programme into overdriveAnd I have some program loaded that I dont want

It says its detected 21 threats and is demanding money ..... I'm stuffed

EXCELLENT

I was thinking to mount a Lucas 12v generator from a MF-28 tractor, as these are fairly well sealed. Would have been bulky & ugly

However, this is much neater & more compact

Its a dynamo its charging

[Vic]

That picture not caused my problem then ?

[Horsley-Anarak]

Looked ok to me.

There is quite a bit of Rogue/Fake Antivirus Malware about at the moment.

Google it and it will tell you how to get rid of it.

Thanks I'll give that a try later.

Now I realise its a fake I can relax a bit and once its stopped from task manager its not a problem until the next boot up.

Mystery where it suddenly came from. I clicked on the picture at the start of this thread, several times in fact, believing it was a clickable thumbnail and that is when all hell broke loose.

OK..... now, back to the original subject. Anyone else crazy enough to have tried this? Even one amp (possibly .6) would operate my LED running lights at night.

[Keith.P]

The original dynamo from the 1930s was 12V but it was only rated for about .23 amp and about 2.7 watts.
In Germany the law on bicycle dynamo is, 3W (6V) or 6W (12V) output of a standard bicycle dynamo has to be reached by about 10 KPH.
( I must be better thing to do)
I will all depend on what type of dynamo you get hold of.
I do have an old dynamo set-up for a seagull but never used it, as I have no intention to do any motoring at night, especially with a seagull.

Wouldn't it be a lot neater and perhaps easier to place a charging coil inside the flywheel on the stator plate and run the output through a rectifier? I have a McCulloch outboard that uses that setup for a 4 amp alternator. Of course its a 28 hp motor. May take some experiment to get the correct number of windings on some laminations.

A starting point may be to take a dead ignition coil and see how many turns the primary has, I think many outboard primaries work at about 6 volts, so perhaps 2.1-2.2 times the number of primary turns, #20 magnet wire for 1 amp output at 13.5 volts [for charging] if memory serves.

Or get a Seagull one to be used with CDI ignition.

[Keith.P]

Whats CDI ignition.

The only outboard I have with CDI is the 84 Yamaha 9.9b, no charging coils though, not that I will ever be use anyway.
I do have a motor with a BTH magneto, most of the old smaller motors never had charging coils, unless it was electric start.

A CDI does seem to be an antithesis to what a Seagull should be.
