Yamaha Tachometer with bus bar not clear on year or part #
703 controls 1988ish 90hp 2stk that runs perfect
On the tach itself
Its not clear to me if G is for green or ground or ?
if B is black or battery or ground or ?
if 12 is for +12v or 12 poles or ?
I know the wires purposes, not which terminals to attach them to.
I got a "Cobra copy" mid 90's that was never completed and there seem to be no concrete info on this early analog tach, if it works I dont want to hook it up wrong and cook it!
at this point I have an intermitent yellow led when oil tank is 3/4 or full
and a working volt gauge.
Id buy a matching used trim, oil, and speedo if I can get Tach working just to have matching era gauges.
