I couldn't really find a spot to post this so if the moderator wants to move it to its proper place, please do.
I am in need of some mental jogging or maybe just a plain boot to the head
. My problem is that my temp gauge is reading 20/30 degrees to high but with the infrared thermometer says it is running at 170. First, the things I have done. Pulled the sender out and removed the teflon tape and thread sealing compound and reinstalled. Still read wrong. Replaced the sending unit. No change. Removed the old/new sending unit and gauge both Steward Warners and replaced with Teleflex units. Still no change. Then checked all the wiring
between the units, replaced wiring
and connectors according to ABYC regs. No change. Removed any and all ground connections and cleaned them. Then ohmed them out, all 0.00 ohms. Still runs 20/30 degrees high while at the sending unit it is 170 with the IR. So..... I'm at the end of my ideas.
Can anyone think of what I haven't done, or done wrong or just haven't thought of? Any and all help is appreciated.
