There was a forum user "Dani" that dismantled a wreck to add a second pack to his car. He had it open with photos of the contactors and resistor, but i couldn't read the value. i had sent him a PM to request the value, but never heard back from him.

Open the small inspection cover on the Motor Control Unit (aka Drive Inverter) and verify that the fuse is blown. Chances are high that the On Board Charger/DC-DC Converter unit has internal damage also if the fuse has blown. Opening the cover High Voltage Precautions You need to charge up your 12V ...

Is the bottom part of the hill (between mile 5 to 17) on an interstate? It seems that going 60-67 mph uphill would be using a huge amount of energy. Of course it doesn't really matter too much because you know you can always coast or regen as necessary to make it back home--but what an awesome climb...

That does seem to be an unusual coincidence. The CMU master component (a microcontroller chip) is shown near the top of the photo on page 2. There are also 4 aluminum electrolytic capacitor not shown in that photo. Plus numerous tiny ceramic chip capacitors. Failure of any of those, such as a hairli...

The boards are not paired, but we have not heard a report of a defect in the top board as yet.

Here is a link to the 2011 radio wiring diagram, you didn't say the year of your car. There is a 12V line fed from the battery thru a fusible link that has power all the time.

...Loosing the SOC entirely with no anomaly on the cells voltage readings makes me think something else (something more ?) is faulty. What if it was the CMU master component (the one that stores the VIN and communicates with the BMU ) that was failing since the beginning ? could it explain both the...

... But from the limited reversed engineering schematic we manage to come up with so far, it seems that the trigger simply & abruptly switch off the relay, thus taxing the bypass (now heated from operation) resistors & caps. Are you referring to the OBC or the EVSE schematic? The trigger se...

... Would it be acceptable to substitute a few LEV50N cells into an earlier car with LEV50 cells such as mine ? ... Does anyone know or has anyone tried this ? LEV50N cells may be the only ones that will be found second hand still with a useful capacity remaining. i haven't done this yet, but i wou...

i've never heard of anyone testing this, but if the HV fuse were blown, would the fuel gauge still show the bar lines for the battery pack voltage/SOC when the key is turned to ON? One interesting observation you made was that the contactors were chattering and then never heard from again. So could ...
