fun accident

The other week dead at a green light, groping about for power, I realized over 5 long seconds that my main contactor had dropped out!

I'd just turned On the air conditioning loading the 12V system down below 10 - ah ha, my 12V battery must not be making good connection! My DC-DC converter can not run so many accessories alone..

I rolled a window down and made a smooth recovery with minimal honking behind.

Back home I confirmed my theory and began to clean the 12V battery connection. With the 12V battery cable in my left hand furiously working it with a wire brush it slipped falling upon the high voltage battery. Zap!

Bitten by my minimalist exposed high voltage battery design!

Death toll:
1 fuse
1 motor controller logic board
12V to 5V USB converter
at least 1 cell monitoring board..



The damage was repaired by Manzanita Micro and we should be on the road tomorrow.  :)
