jetrinka Huh. Good to know. Thanks for that little tidbit.

illinipo the system will draw more current when it needs it, the more current it draws the more load the alternator puts on the engine to meet the draw. Its somewhere around 1hp/25amps. so if youre operating your alternator at full capacity its taking about 4-5hp. normally you only use 30-50amps so it only takes 1-2hp.

jetrinka What benefit does this offer? Its not like the alternator has a clutch like the ac compressor that makes it freewheel. It has pretty much the same resistance to turning no matter what. I don't believe its resistance increases even when its full fielding.

Yeah I did this I think I put it at at 13.6 or something to turn back on. But i'd rather not deal with the lights dimming and such. Probly just gonna turn it off and set voltage to 14.2. Been running 13.8 but after I just did some reading im gonna up it to 14.2...

The alt voltage turn off is only for 15 sec then it comes back on for 15 sec with a 4 sec delay after you come out of WOT

illinipo Yeah in the SCT value file it was at 14.4V and set for something like a 2 second delay before turning off and 5 second dwell before it turned back on.

Sounds like I'll be turning this off...
