These are basically a relay with an op-amp comparator to control the position.
Above ~14 volts, the relay should open (take the alternator input away from the battery) Below ~13 volts, the relay should close (putting the alt output back onto the battery). The deadband (should not change state) is between 13-14. So if you had a variable voltage power supply, you could check the transition points. I know the older units in the type-I engines were physical relays and you could hear them buzzing when they were working but hard to hear over the engine noise and are not doing anything unless running. The newer ones you can buy now (solid state) have no moving parts so make no noise. |
