Are the batteries really isolated during ESS stops?

Yes, lots of noise when starting. This scope makes it easy to transfer the image.

That kind of noise isn't kind to things.

Nice scope! I came home after Thanksgiving with a 12-bit loaner to play with for the next month.

Those narrow pulses in #302 are only one sample wide. That scope can store at least 10M pts per channel. The waveforms can look even hairier.

K1 run/stop relay is blue

Cold start then ess start.

Cold start alternator current. Blue is current.

This is an interesting thread over on the Wrangler forum. What is the cutoff voltage for the aux switches? My experience is that it happens around 12.4vDC. This is volts measured with a meter from the battery. Have any of you tested for the cutoff or do you know what the documentation says?

Lower than that .... I've seen 12.1 on my JT and they work, on my wife's JLU it got down to about 12 and she saw the message.
BTW, this is the Gladiator forum

I think I saw the voltage setting in jscan once.

I not only wrote Gladiator instead of Wrangler, I forgot to post the link. Fixed! The struggle is real!
