Brand new teleflex 7000 rpm tach
Yamaha 50 2 stroke
I have the teleflex tach hooked up properly to the yellow/green/black leads on the wiring harness in my console. At idle it works great, says I'm getting 800-900 rpm like it should, but when I begin to hit the throttle once I reach about 2000-2500rpm the tach will stop and then go back down to 0 even though the engine is obviously running much higher.
I did some searching and I might need a resistor? Anyone see this issue?
Previous searching yielded this:
3. Some Evinrude/Johnson 48 (50), 88 (90), & 112 (115) "Spl"
engines may require the addition of a 1/2 watt (or larger), 2000
ohm resistor, connected between the Tachometer's "Send"
and "Ground" terminals. If the pointer drops back to "0" as the
engine accelerates (around 3500 RPM), the resistor is needed.
Replacement 12 Volt Light Bulb (with wedge base socket):
Teleflex Part Number - IA62995
