Hey everyone,
I bet this was asked many many many times but I can't seem to find an answer with the search.
I'm looking to power and interface some electronic circuits to the car electrical system, I don't know too much about cars my self but I know that the electrical system tents to be very noisy.
So what kind of protection is necessary ? And what does it protect against ?
I've read somewhere that the alternator causes noise with very high amplitude, both positive and negative.
Is there anything else ?
Reverse battery polarity ?
And short circuit conditions ?
How do I protect against these ?
Just fuse+series diode (polarity) and some clamping TVS ? Anything else ? Is there any working tested circuit ?
Thanks in advance, Mike.
