Hello Forum Members,
I have an old Jeep that originally had a 6 volt electrical system. That vehicle was converted at some point to a 12 volt system. I am installing an original 6 volt fuel gage, and therefore need to drop the voltage in the fuel gage circuit (prior to the gage) to 6 volts. In order to do this I am using an NTE962 IC voltage regulator. The wiring seems simple enough, but I am having problems. With no load, Vin of 12V and the center terminal of the regulator grounded as required, there is indeed 6 volts as measured between the Vo terminal and ground. But with any load applied to Vo, the voltage immediately drops to about 1 volt. This happens when the fuel gage is connected (approx .5A), or when a small 6V bulb is the load. The NTE962 is attached to a piece of aluminum as a heat sink, so I don't think temperature is a problem.
Any suggestions?
Thanks, Brian
