hi guys bought a 18 center console wellcraft with a 150 evinrude 1987, bought new gauges the old ones weren't connected and not wiring, I need to connect the tachometer, the temp and battery gauge any help with that thanks.
No diagrams with the new gauges? Ground to each gauge. +12v with key on to "I" terminal on each gauge. Temp sender wire from engine to "S" on temp gauge. Fuel sender wire goes to"S" on fuel gauge. Light terminals on each gauge goes to NAV position on NAV/ANC switch. No sender for voltmeter.
