G'day all,

A quick question for some knowledgeable folks here....

I just bought a second hand, 15hp Yamaha two stroke outboard - approx 2006
model for use on a tender.

The motor has what I know as a "charge kit" fitted which looks to be a
rectifier with wires coming out of the front of the motor that have lugs
that connect to a battery to provide charge when the motor is running which
I guess would run lights & sounder etc.. on a small dinghy.

As the motor will be used in a stock aluminium dinghy I have no need for
onboard power and am worried that the wires may end up shorting out & doing
some damage, or worse still causing some type of damage to electrical
components due to it not being connected to a battery.

The "rectifier" looks easy to remove (just a single screw) and is only
connected to two green wires coming out from under the flywheel which look
like they have factory "push plug" connectors on them.

Can these green wires be simply disconnected, appropripiately insulating and
tying off so they don't get caught in any moving parts, or should they be
connected to something else to soak up the appropriate "load" from the
alternator or whatever is hidden under the flywheel.

Thanks in advance,

Gary.

Gary, i would say yes. But one thing is to note. is the engines spark
provided my magneto, or by coil?

in other words, can you rope start the engine without a battery hooked
to it?

If so, then disconnect as much of the wiring as you feel.

I ran across a similar problem last year with a 2003 Johnson 25 2 stroke.
All of a sudden it started to stall and was very hard to re-start.
Took it to the dealer and he said a couple of screws had worked loose and
damaged a coil. He said if I wasn't using the semi-complete charging
system, I should just remove the stator, replace the $40. coil and all would
be well. He was right.

Just tape the wires to a solid connection. When you sell the motor, may
bring some extra bucks. Not having a battery connected is no problem. I
ran a 15 hp Mariner for 12 years without a battery connected to the charging
circuit.

OK, so it's mag style ignition. I wonder why he said to remove the
stator coil? Because when it's unhooked, it just goes for the ride.

Hi All,

Thankyou for the advice and comments.

I have disconnected the kit from the "two wires" that come out from under
the flywheel, insulated and secured them.

Motor starts and runs fine without anything connected so I guess all will be
well.

Regards,

Gary
