Mariner Charging Circuit?

[mmgarrett]

I have a 1986 Mariner 30hp manual start. Is it possible to add a charging circuit to this motor? If so, what would it take? I would like to run lighting, vhf, and fishfinder.
Thanks,

Should be relatively easy.

You'll need a charge coil (also known as a lighting coil) under the flywheel - this may or may not be an integral part of the a ignition coil assembly. If it is, the tell tale will be wires from under the flywheel that don't connect to anything, if you find that, you probably don't neeed to buy one) Fun bit is removing the flywheel if you donlt already have the coil under there.

Then you'll need a regulator / rectifier. This is where I can only guess as to whether youll need one or two bits - some systems integrate both into the one lump of plastic, others use separate components.

Then all you need are a couple of wires to your battery - and if you aren't using a starter motor they can be sensibly thin.

If you can let us know the serial number, there are microfiches on Ishop, which hopefully will confirm the answer to both these questions.

Thanks for the info. Model # 30AM Serial # 689-(S)000391. From under the flywheel, there are three wires coming out: White, Brown, Black. Any more help would be great.
Thanks,

The bad news is that you don't seem to have a lighting coil under there.

The good news is that it does appear to be available as a new spare part ($80 ish), you'll also need a rectifier ($60 ish) (Prices form the Ishop Marine website). If you can find someone breaking an old one the prces should be a lot less, and you can also see how it;s fitted.

The biggest PITA is going to be etting under the flywheel to fit the lighting coil, but other than that it shouldn't be too difficult.
