BMV 712 temperature reading is half what it should be

I've connected the BMV according to Fig 4 of the Quick Install sheet for the BMV-702, and the reading is 30 degrees F - about half what it should be. Any ideas? Am also using a Multiplus 12 v 2000A with its own temperature sensor.

How does the temp sensor work?

Forgot to mention that, unlike the Fig 4, both of my cables have the fuse in the middle of the wire. Is one of the wires perhaps the wrong one?

Update: The temp reading is 30 degrees F and it never changes. I think it's also mis-indicating the amp-hours remaining because it thinks it's so cold. I need to fix this.

Hi,

"both of my cables have the fuse in the middle of the wire. Is one of the wires perhaps the wrong one?"

I suspect so.

It sounds like you have two voltage monitoring leads, and no temp sensor PN ASS00100000.
