Houston, we have a problem!

After driving the Fiat to work this morning, went to connect the charger and noticed that the high voltage cut-out led on my management module was on.
A quick check with a DVOM showed that the fault was in my left rear battery box (instead of daisy chaining all the optos together I run the wires from each of my 4 battery boxes to my management module and connect them together there). Lifting the lid, I could see the culprit by the illuminated load led.
The moment of truth, was it a software lockup or a hardware fault. Reseting the pic with the reset jumper made no difference, so I removed the board and had a closer look. Found one suspect solder joint, resoldered and tested with bench supply, all back to normal.
P.S. Peter, got the screw terminals today. Thanks.
