Red Wires ???

[frank hollman]

Hi,
I've looked through the previous posts to no avail. Maybe someone can help. Not long had the boat and still finding my way around. On the old electric start 20 HP 2 stroke Yamaha (No. 20A 653S 00809) there are a pair of red wires coming from under the flywheel connected to nothing. I've bought a new battery and the engine starts and stops on 2 remote "Push" buttons/switches ok.

I've followed all the wires to and from the switches, the engine and the battery and it all seems to make sense. But the question is - Is anything charging the battery and what are these red wires? I tried the multi meter on them with the engine running and got a DC voltage of 4 -5 volts at tickover and rising as I increased the engine revs. On AC scale I'm getting a steady 12 Volts + on these wires

Can I use this output to charge the battery? If so do I need a rectifier? And if yes are they still available

Sorry for so many questions on the first post but, any help would be appreciated.

regards

frank

Hi.

I have a 20A manual start. I think the wires are for a lighting system of battery chargeing sircuit, if you dont have a rectifer and need one the part number is 648-81970-40.

Thanks Clive

Can I ask have you any idea of the charging rate of this coil in Amps.

Also where do you get spares form for the 20A. I'm in Nottingham, UK and a local Yamaha dealer doesn't seem to have a lot of interest in this "old" engine

P/S
i have the same motor (20AE)...will look tomorrow for the wires!

[ressiv]

the red wires are connected to the 2 red/gray cables that comes out of the inner cable-harnass..
its hard to see but possilble connected to the rectifier...

Thanks ressiv

Yes thats what I believe It's just that mine don't connect to anything and its that rectifier I need. I'm having problems finding one in England - Most keep sucking their teeth and telling me its an old engine Hahaha I know that !!!!

Thanks
