Installed dual battery relay

No issues, I am putting a dual battery system in. So I wanted to see before and after current readings.

Installed Blue Sea battery switch

The shunt is connected to the IBS with a right angle copper bar.

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.

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.

Cold start alternator current. Blue is current.

Has lots of fun for $60. Manual control of battery charging.

I have a current shut on my batteries. It records voltage and current. Minus is out of batteries and plus is into batteries. During the ESS event the current is -25A that is stereo on a/c off. So, the time the engine is shut off the current is -25A. After starting the current is +50A for less...

Victron battery monitor The graph only works 10 feet from Jeep, but the volts and amps from the first picture I can see inside the house.

Cold start then ess start.
