Indeed it is brown. Wraps up the front of the L head, under the fuel
rails, twists a couple times around that bunch of grounding wires that
bolt to the head, then hits a little connector and turns into the
blue/black wire.

Thanks for the tip.

Speaking of tips, ALL the wires look brown with a thin coating of
central Oregon dust on them. A bit of Windex (all I had) washes them and
the colors pop out.

Well, THERE'S your problem. The oil pressure lamp on the dash does not
come on because the op switch does not close with no oil pressure. Short
that blue/black wire to frame and Hey Presto! the lamp comes on.

I gotta pull the tin anyway, wonder what I'll find. Those pressure
switches fail much?
