1961 Evinrude Wiring Diagram needed

[edwjosp]

I got a 1961 Evinrude 75 HP outboard motor and it starts when I try to hook up the battery. I figure this is a grounding issue and was gonna try to find what wire it could be but the wiring diagram on the motor housing is wore away.

Model#: 50525
Serial#: 06237

The diagram in the parts catalog shows the battery connection in the switch box. You can examine it on page 20 here: http://www.marineengine.com/parts/jo...rude-parts.php
