ICON Pro Gauge: TRIM Values
Posted: Thu Feb 22, 2024 10:36 am
My recently purchased boat has a 2012 E-TEC 175-HP engine, installed with the MWS harness and with ICON Pro gauges.
I want the engine TRIM to properly show on the ICON Pro [RPM] gauge, and then I will add an ICON Accessory two-inch TRIM gauge.
I checked the wiring and the trim sender wire ( white/tan) is connected to accessory wire 8. [Perhaps means at lead P1-8 on the ICON Pro RPM gauge wiring harness.] I checked the setup on the gauge and configured input 8 for trim with EVINRUDE setting. Tried calibrating the up-down as well.
After calibration, the TRIM reading [on the ICON Pro RPM gauge] shows a 100-percent (or eight segments on the thermometer bar graph] but when the engine is trimmed down just a bit the display goes to 0-percent.
I even tried calibrating full down and just halfway up to see if that affected what I see on the display.
I tried disconnecting the trim sender wire and metering the resistance on that wire wire while trimming but I'm not getting the readings listed in the other posts. I read getting like 400-Ohm in the full down position and O when the trim hits the point from trim to tilt.
I also read somewhere that maybe I should use pin 7 input instead of pin 8.
Any help would be appreciated, thanks.
