Re: (ET) Card 4 woes

[Christopher Zach <cz alembic crystel com>]

Pretty much. The two pins that burn up the most are the two that control 
field current to those diodes. I simply soldered 14 gauge wires to the 
diodes, then used normal insulated blue crimp on disconnects for those 
wires and the two on the harness/plug. To keep me from plugging in 
backwards I used the male/female properties on the card and connector ends.

Simple, no more problems, card 4 can still be easily removed.
