I agree - with the spike being able to reverse the polarity AND knowing how many different hands were helping with getting the last things wired - I am ALL to aware the voltage could have been reversed at some point.

I am not sure if reversing the input polarity to that particular converter would "let out the magic smoke" - but considering the cheap price I wouldn't be surprised that there is no protection against that.

Any suggestions for a more robust DC-DC converter? I like the idea of using the 6V from the side car, but not if we can't turn on/off the light.
