I am trying to fit a reset-able fuse to protect a Charger I have fitted into a car. I think I was having a problem with a "Load Dump" destroying the circuit so I fitted an MOV across the supply.
The whole circuit draws 2 Amps at peak current draw. However when using a blade type Auto fuse I had to fit a 15 Amp fuse otherwise it just blew.
I want to protect my charger but at the same time dont want to be changing fuses all the time or having to do repairs because of the load dump.
I have attached the drawing of my proposed circuit I am looking for some advice so as to be able to make sure I have everything covered.
In the Load Dump i read on line about excess voltage and current in Alternators causing damage. I am assuming this is the problem.
