This is an A-BMS 12V installation?

Anyhow, it your 100% sure the senswires are correct then it sounds like your BMS is broken.

Thanks for the reply you are correct i replaced the bms and bingo was online.

Now the next challenge is to load firmware via wifi module to allow for dual bus usage ,I have installed firmware multiple times with a successful indication from the wifi. The software is 2.90-2 but it doesnt change in the bms module it stays as 2.90-1 which is great if you want a single bus system .help please....
