More tachometer stuff!

[Toontime]

1994 evinrude 88 spl. Tach works to wot then falls off to 3,000 give or take a few. Traced sending wire from tach to plug in the control box. Can anybody tell me where the sending wire connects at the motor? Has evidently a 6 amp unregulated charging system from what I see on the head. Would prefer not to tear everything apart to trace wires on a holiday, LOL. BTW, have a happy 4th!

Evinrude/Johnson “Specials” (48/50, 88/90,112/115 hp etc.): If the pointer falls back to “Zero” when operating at about 4000 rpm or higher, you may have to add a 2000 ohm, 1/2 watt (or larger)resistor, connected from the “Send” to “Grd” terminal.
