DC-DC Overcurrent Malfunction

Porsche 914 EV Conversion

After some experimentation today, I found that under a moderate load of 8 amps or so, the DC-DC eventually stops working and fails to charge the 12V battery. I was misled a few times because when I turn off the key for awhile and turn it back on, the DC-DC starts working again for about 30 seconds before stopping. It's good to get the extra transmissions out of my garage.

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.
