I bought a Kimdrox DC-DC adjustable regulator (solid state) to replace the original unit with which I was having trouble. Amazon $7.29 including shipping. Chinese of course. Seems to work great. I started up the engine and when the thermostat opened up (which I could see from the movement of the gauge) I adjusted the regulator so that the gauge read 160 deg. The gas gauge is also now reading properly.
You will have to rig up a mounting using 4-40 bolts.
A bonus is that the LED reads battery voltage for which we do not have any indications.
