That is great information. I tested the replacement regulator again this morning before I install it, and this time it read 2 ohms from ign to output. I think I was not making good contact before and maybe even this time as well. Anyway I installed the replacement regulator and the gauges read as one would expect. The temp gauge goes up much slower and rested at about 1/3 hot on the gauge. If the problem resumes, at least now I know what to replace. Thanks.
