I've been having an impossible time trying to get two separate temperature gauges to work, and you would not believe the headache of it all. First off, I have a pilothouse, and so with two wheel stations, I need and want dual stations for temp and tach. I have installed all the hardware, but have been trying for about 6 months to get the gauges to work.
Before anyone jumps to conclusions, I know I need a dual station sender, and that has been the problem. I've also checked the actual engine temperature with independent means and it is normal at a coolish 165. I've been on the phone with Teleflex tech support to no avail. I have the proper identical gauges, all the wiring is perfect, and works fine with my old single station sender when they are hooked up one at a time. So I have narrowed the problem down to the sender itself.
Turns out Teleflex doesn't make a 1/4" dual station sender. There went 5 months of effort with Cook Engine in Portland, Oregon sending me and then resending me the wrong temperature senders. Holy moses
Finally, after hours of my own research online, I found out that Sierra Marine, an offshoot of Teleflex, makes the proper sender. So I order it, it comes today, and I install it, and they still doesn't come up to temperature!!!!!!!!!!!
Most things take patience, but this is ridiculous. Power boats across the land have dual stations, and I can't get this simple installation to work.
Gauges new and identical and suited to dual station use.
Gauges work properly when connected to a single station sender and come up to the accurate 165 degrees.
When connected to the purported proper sender (TS26651)they do not rise above a reading of 120 degrees.
I'm defeated, and furious, and flabbergasted.
and any help whatsoever that solves this problem will earn my profound appreciation.
