JBD BMS troubleshooting

[Barold]

I have an odd situation with my JBD BMS (I think this is the cause).

The BMS seems to activate when I connect the cell monitoring harness (I measure 13.5V between the battery terminals, and at the B- and the C-. But when I connect the battery to the circuit, I do not get any voltage or current through - is there something I am missing with the setup?

Thanks!

Do you have the app for the bms if so what is it showing

Is there a port for the temperature probe? In some cases, the absence of the temperature probe is seen as an absurdly low temperature and the BMS will give you the middle finger because of that. Plug in the temperature probe and it starts to work.

Aha! The temp probe wire was frayed and almost pulled out of the plug... are these available generally (like a robotics/electronics store) or should I try to repair it?

It's likely a standard plug. I haven't had to repair one.
