Temperature Gauge Reading Hot

[pjmoreland]

My temperature gauge has been registering high temps whenever the engine is under load. I did a ton of searching last night and stumbled onto a post where someone had the same issue, but had confirmed that his coolant was not hot. He tracked the issue down to a bad voltage regulator. I measured my system voltage when revving the engine, and it was going way up to above 17 volts. The contact in my voltage regulator was fused shut. I replaced my voltage regulator with a solid state unit, and now my temperature gauge is reading normally. This site is such a great resource! I will probably convert to an internally regulated alternator at some point.
