No power to EIS

Hello again. So, this past weekend a friend and I well he had applied 12 v (he couldn't remember which fuse he did) that have no power 78, 79, 80. At both sides of fuse no power. When he applied 12 v then I turned the key to start the fuse blew. It was a 5 amp and a 15 amp do you think the EIS has an internal short at the start position? Also need to verify if there is a constant 12 v going in EIS. Can there be something turned around (polarities) so when I turn the key to start it causes a short? Just a thought.

Almost forgot battery test was a go it passed second test. The battery was at 11.3 V I was told first it did not pass load test I mention was that because it had 11.3 v she replied maybe. That just rubbed me the wrong way told her if she is going to charge the battery to do another load test. Also my key came out of the ignition after battery was charged.
