First commute did not go so well… Didn't even leave the garage… Was late for dentist, so only had time for a couple of troubleshooting steps , mainlyconsisted disconnecting the vacuum servo, figuring that the last thing I connected so therefore was causing aux circuit to drop to 6v? Turns out all the complex BMS, control logic, uP, etc were undone by old fashion corrosion on the aux bat terminal.. Doh!… Cleaned it up no volt sag, all systems good now… School boy error. Oh well tomorrow's another day…
