Hello,
I am wrestling with an Li-Ion battery.I am looking at 5 contactors in the battery pack.
The precharge relay contactor has a coil resistance of 75 ohm
The lower high voltage contactors (200v) have a coil resistance of 30 ohm
The Kilovac EV200, the high voltage contactors (400v) both show no résistance ...... open circuit between the black and red wire...... could the coil be dead ?

The Kilovac EV200 most likely have a built in current limiter for the coil, and needs dismantling for messurement. (small box on the side of the relay)
