One question I had on the use of *two* diodes to limit voltage from the battery compartment to outside world is as follows:
Picture the following scenario:
We have a normal 144 DC battery that needs charging
Current flows into the positive lead to the battery from the charger
Current flows out of the negative lead back to the charger
With this in mind, if we use two 'safety diodes' to protect the user from danger, the diode positioned on the positive lead keeps the current from coming back towards the operator. This is the normal flow of current when charging.
While the second diode *allows* the current to pass right through it back to the operator since this is the normal direction of current flow back to the charger.
So how does the second diode keep the negative battery lead from becoming a source of concern for the operator if utilized for this purpose?
Jim.
