Fixing the DC-DC Converter

Porsche 914 EV Conversion

I cringe at the thought of having to send anything back to Electro Automotive for replacement or repair, so I took a chance and dissected the DC-DC converter to see if I could fix it. Here's the DC-DC converter taken out of its black aluminum case.

DC/DC converter blown

Porsche 914 EV Conversion

Well, I ran out to Radio Shack this morning and got some more 5 amp fuses for the DC/DC converter. It looks like there's a pretty serious short in the DC/DC converter. After plugging a fast-blow fuse in, powering up the car blows the fuse. I tried a slow-blow fuse and that went too. I then disconnected the 12V battery to see if that was causing a problem and it still blew a fuse.
