It's staying around 14.6v and up, yes... I've seen it drop down to a 13.6 once, on a "Warm Start" after gassing up, but by the time I got out of the gas station it was back up.
Got one, It's difficult to find a single point to check the whole system because of the wiring harness layout (No real single point to check cause my clamp isn't big enough to do the big bundles coming off the battery) This is my multimeter. to show the clamp;
That’s what I’m confused about. Every time I’ve been at 15 volts was during the day. Really no electrical extras running. Just some running leds and radio/amp on at low volume. Have seen it with a full trickle charge and with out on the battery. Seems to happen just driving normally. I’ve noted it 6 times. 2 times it stayed at 15 until shut off. Other 4 it came back down then fluctuated normally (13-14 range)
Oh I'm definitely still right. The 400 watts is the max output. The inverter takes the 12v DC from the battery and converts it to 120v AC at the outlet. So it's 400/120 not 12
Except if you look at the OP's original post he mentioned the potential max draw of the inverter.... So again reading comprehension
The steering rack isn't a continous load. Its fused at 80A, but only would get close to that draw when turned hard over and held there. Doubtful your upgrade plays any role in the overall amperage budget (considering the original rack drew close to the same, for street purposes at least). I would clamp the inductive pickup to the alternator main lead, then check power output at no load idle, then turn on accessories and watch the output. Remeber "surge load" will be handled by the battery, but the alternator will need to make up that amperage use over time, so give it a few minutes of runtime at high load to see if it gets even close to its max rating...my bet is it doesn't...but 38A of audio is nuts also! Must be one "bumpin system"!Got one, It's difficult to find a single point to check the whole system because of the wiring harness layout (No real single point to check cause my clamp isn't big enough to do the big bundles coming off the battery) This is my multimeter. to show the clamp;
I did measure the Amplifiers' current with it, that was a max of 38 Amps with a pretty punchy song at 24.... I should be able to measure the steering rack the same way.... But I got some other stuff I gotta do before the parts counter closes, so,
to be continued....
The max draw of the inverter is nowhere close to 40 amps. Surge output of most inverters is usually 2x it's standard output so at most 6.66 amps. You really like being wrong. This is fun.
Inverter draw on the vehicle’s electrical system for a 400 watt inverter at 12V (because this is what a vehicles electrical system is , NOT 120V) is 33.3 Amps, which is what OP was talking about. He was clearly just rounding up to ~40 Amps. Vehicle running at 14-15V it would be about 26-28 Amps.
You are so wrong it's becoming laughable.....
Alright, well I said I'm not an electrical engineer. Turns out those were holiday inn commercials were just marketing
