Hi all. Ive decided that I might sell my boat this year as trailer boating just isn't for me...too much stress!

So if anyone might be interested before I send the details to a broker, please let me know. Regards

Thanks, so no need to worry about the lack of 'S' terminal and just wire up the light to the dash as I did earlier?

Should get the carbs back next week, so will fire up then and let you know. Thanks for all your help, we got there in the end.

Without at the moment as I have my carbs off being cleaned.

I just thought I needed the full whack at the coil for starting purposes as this thread started because I was struggling to get going with the 11.8v

Nearly there! I rigged the system up as in your diagram except I haven't got the 'S' terminal so just used the IG and L. Charged the battery all night so that I am getting 12.7v at the coil with nothing connected to the alternator. Rigged it up as shown and the bulb lit up :thumbsup: However, I then...

Im losing the will to live here, as many of you reading this are probably to.. :grrr: So Ive been out tinkering again trying to rig up the lamp however I can't get the lamp to light up. I connected the wire off the small terminal off the back of the alternator and with ignition on, no light. I tried...

Probably the latter.... ....not!

It would be no hardship to run a light upto the dash anyway, so once Ive had a trial go with the bulb, I'll connect it up properly if all seems to work ok. Can't thank you enough for your input and that diagram will prove invaluable.

Its slowly making more sense.... :thumbsup: The coil is still fed direct from the ignition for which Im now getting the full 12.6v but only after I take the diode off. If I reconnect the diode back onto the alternator, the voltage at the coil and through all of the ignition live feeds all become 11....

Excellent, all makes sense but again, just to clarify :oops: . Yes I do have the two connections, like you say the heavier red charge wire and the lighter one which is the one in the photograph with the in-line diode. This one goes to the + side of the coil. At present I have disconnected this one i...

Many thanks, I had to read that a few times before it eventually sunk in :notworthy: So just to be sure, as the thought of 250v AC does scare me a little, should I fire up the engine without the diode connected and measure what Im getting out the back of the alternator? If its 13.6ish then I can get...
