Jeep battery and alternator current

[J Sierra]

CH1 is N1, CH2 is alternator current, CH3 is starter relay, CH4 is total current (main ground). Note current scale for CH2 and CH4 are not the same. CH2 zero is bottom, CH4 zero in the middle. The current scale at the right corresponds with the color of the channel.

I am glad you sent something that Shadowspapa will understand. I like the colors!

I love graphs, but I'm kinda over straight lines. I like dynamic things.

I wish I had 4 channel scope but usually my 2 channel does all I need. In this case, I think needing to capture all four events in a single data time-line may be necessary to see, and analyze these four events, correctly.

Could you identify the probes or shunt resistors you physically connected so an exact same test could be repeated? Along with the brand and part number of the current probes you used although, I can figure out suitable ones to get & use. Perhaps send me an email with a snapshot of where you connected, and clamped your four probes? KsevenTXzeroATgmaildotcom

Pictures of the set up. The probes are not the ones that came with the scope. On N1, N2, starter relay and PCR relay are standard 10X probes. The current probes are CC-650A Hantek. One current probe is on the alternator cable and the other is main ground cable. Starter relay has a test point on top.
