16v on car electrical

[ssh 924]

So I see aftermarket h/o alts can be regulated upwards to 15v but I also see others doing 16v+.

So is 15v safe to run on stock electrical but 16v+ needs changing wiring and fuses?

I'm more interested in actually having the alt do 16v, not 18v charging 16v battery

So what's involved in running alts with 16v in a car safely?

Most people do one alt doing 16v for the sub amp, and the stock one doing the car and the 4 chan.

That makes sense, thanks

Yeah your cars electrical will fry at 16 volts.

is 15v safe on the cars electrical or a bad idea?

Probably a bad idea. I would try to stay below 14. It would suck to fry your ECU.

Ya it would. I know Alts from dc can be regulated from 14.4 to 15.1

What kind of vehicle? Maybe you could get a bracket made to run two alternators and keep your stock electrical separate. Then you could run 16v with no problems.

You could do it, but you'd have to isolate the 16 volt system. 16 volts isn't usually 16 volts. The resting voltage on a 16 volt system is usually around 17.2 so the 16 volt "charge" from your 2nd alt would have to be higher than that. For comparison the resting voltage on a 12 volt system is usually around 12.6 and the charge to is is high 13's into the 14's.....
