surge protection

I always thought that the device that regulates the load called a motorcycle battery regulator and could not be otherwise, is in my view an electronic device rudimentary and unreliable. Many would have happened that one day the bike would not start and without thinking twice have decided to change the battery and everything solved but a few days they meet again with the same problem, it is found that the fault is the regulator and that is when they hear the price and I'll say so, without anesthetic or anything .
So many choose to manufacture their own device and depending on the design of their choice could be that at some point fail to adequately regulate and stop and the worst does not regulate anything and end up frying some electronics.
This protective circuit just after I came to attend a forum to post a regulatory circuit that some were making a home.

The circuit is simple, I have not tested but should work .




Components:

The relay is NC (normally closed) when no voltage in the coil, remains closed, allowing power to be delivered from the regulator to the battery
( normal operation) must take into account the intensity that will run on 10 amp contacts would be sufficient.
The thyristor is a zener diode
BT151 18voltios 1 / 2
watt 330 ohm resistors 1 / 4 watt
The diode in parallel with the relay coil 1N4007 is a



Operation During normal operation (the regulator is doing its function) relay contact is closed so the battery charges, all normal.

If the controller fails and loses control, close to 18 volts, voltage appears on pin G of the thyristor, the relay is turned on and off the positive battery regulator and therefore the rest of the electrical circuit bike, will remain in this state as the voltage does not drop. You may Andira
a led to witness in this state.
