Anyone know how to bench test the voltage limiter?
From the service manual, the propose of the voltage limiter is to regulate the battery or alternator voltage input voltage to a constant voltage of 5 volts D.C.
I tried to test my voltage limiter today by connecting the input terminal to battery positive, and using a multimeter from output to battery negative. But this gave me 11.92 volts, i.e. the input voltage.
Any ideas on how to properly bench test the voltage limiter?
