Johnson 8hp Sailmaster

[Zephyr-Jeffer]

Now have 1984 Sailmaster outboard and I would like to test run before putting away until next spring.
Have no manual for it, so I have to ask:
There are two electrical wires coming from the front of the engine. Though it is pull-start, do these two wires need to connect to a 12v source? As an On-Off switch, maybe?
Does this mean it has electronic ignition? If yes, a motorcycle battery with full charge should work?
thanks for the help.

Alternator? Run the motor and measure for voltage/amps off the wires. It's used to provide a trickle charge to your battery.

Yup.. a little alternator that can make about 6 amperes at almost full throttle.. Ignition works without external power. Insulate the wire ends from the alternator if not using so as to not damage the rectifier..

Hey. THanks. that simplifies the test run.

Alternator, cables to hook up navigation lights.
