Re: [OMC-Boats] 1964 OMC Johnson Deluxe - Wiring Diagram?

Jeff, here's a couple of resources:

I made a web-html-spreadsheet that shows the wiring colors on my 66 150 hp
Sterndrive.

You don't need Excel software to view it. It should be very similar to your
64.

You will see tabs at the bottom that group wiring functions by physical
location. Scroll down to view instructions.

You can also click on the where the blue hyperlink to view "distant" end of
the wire connects to. See:

http://hhscott.com/evinrude/docs/electric_all_66.htm

Also, if you are a more visual learner you may view the BLACK & WHITE
factory (1968) schematic here:

in)

A later (1973) full-color sterndrive schematic is here, but it was for
generic OMC OEM boat builders, not the E_J_O boats as above.

What is the symptom that makes you think the ammeter is bad?

The factory used in-series, full-current flow Ammeters. By that, I mean
there were no parallel current shunts that proportionately divided the
current flow. An ammeter isn't likely to fail, but after 40 yrs, I'd first
start be inspecting and cleaning all the wiring junctions and connections.
You can easily bypass the meter by safely joining it's wires together. You
could easily test the ammeter, by taking it out of it's circuit (remove the
wires from it) and then testing it with a VOM or test lamp in circuit. If
the ammeter won't pass current to light a small test bulb and it's needle
doesn't deflect under load, then it probably is bad.
