I just tracked down my motorcycle's fluctuating temperature gauge to a failed 7 volt regulator. Apparently the gauge runs off 7v across the coolant temp sensor/thermistor to move the needle. My regulator jumps between 7.5 volts and 10+ volts output, so the gauge was always fluctuating in the hot zone. I installed a spare regulator, and all is well again. Since my spare is now the primary, I would like to build a new spare. Since the regulator, about the size of two thimbles, is completely potted and I don't know what's in it, would anybody know what components would be needed to build a 7 volt regulator? It would have to operate within the typical 12 volt automotive range input of about 10.5 volts to 14 volts and output a steady 7 volts. When I supplied my temp gauge with 7 volts from my bench PS, it was only drawing about 100-200 mA @ 12 volts, depending on the resistance of the temp sensor. Anybody know how to throw one of these together?
