I need your input. I was recently getting error 123, and isolated problem to the backboard. Ordered online and just replaced it. It is now working, but I still have some concerns.
The voltage at the test port 1-8 is about 80V (should be 75), and 2-7 about 70V (should be 65). 3-6 and 4-5 is normal range. Also the cell voltage reads around 33V (should be 22-28). Is there something else wrong or are these ok range?
BTW, the old board was burnt at the main harness from the transformer (two of the pins were smoked)
Thanks for any input!
