[Oeva-list] DC - DC converter

Hi Phil,

  There is no standard wiring color code for converters.  Since you got this off Ebay, does the prior owner know anything about the wiring diagram?
  I'm also a bit concerned that the DC-DC converter is not isolated.  That is, the 12V side and the 30-60V side have a common ground.  It's generally best to have your 12V and traction pack voltages isolated for safety reasons.  
  This looks like the same converter as the one here:


This link says that "Yellow wire is output, Black ground, and red input."

Perhaps you could contact him for more information.

I am converting a shaft drive Honda CX 500 to an 
EV.  I purchased a DC-DC converter off Ebay.  Unfortunately the 
writing is in Chinese and there is no wiring diagram.  Is there a standard 
wiring color code for converters?  The unit I have has a yellow, black and 
red wire coming out.   Any suggestions?
