I don't believe for a second an alternator (with a regulator onboard) and a 12v battery would ever allow transistient voltages to rise much past 18vdc let alone 200vdc The battery would absorb most of the spikes. And lastly... if this was true why is it i've yet to see a car stereo or infact any e…

Some things are like fish stories. The hands keep getting farther apart with each telling of the big one that got away.

The short answer is that it can't without some help, '200' A represents a very low resistance. However a 10 A load switched on at the end of 4 to 6 meters of 1.5mm wire connected to that 200 A current source can create short pulses of that magnitude easily. When you realize that in a car the wire, w…

Most of the thoughts expressed were mine when dealing with an issue I had about 25 years ago with a micro that intermittently reset itself.. A couple of beads fixed most of the issue, a pair of 100 pF caps did the rest. Since the wires leaving my device were well protected initially ( I Thought ).. …

What am i missing? That others seem to know about who keep telling people this? Who are the others? Perhaps the "others" heard it from a psychic talking dog.

No one that knows what they're talking about. Only those losers over at JEDEC, for instance... XD

The condition with dirty battery terminals or worse a full load drop can easily cause the alternator voltage to go to several hundred volts but not often or for long.. If it is dirty terminals the transient can occur, A load drop is just that, when the battery is disconnected from a working alterna…

Relays switching on and off will also cause localized spikes. I've seen people measure (DSO 1MOhm inputs) upwards of 200-300V transients (on the order of uS or shorter in duration) from these. This is the cause of amplifier "thump" in badly designed aftermarket audio setups.These spikes though are v…

Maybe they mean on the HT side, but of course that's in the 10s of thousands, not hundreds.

What's the biggest current drawn by a starter?- maybe they mean amps?
