I found that a 60A fuse and the HD LMP fuse in the under hood electrical boxes is causing a problem, if the HD LMP fuse is in the volts to the starter drops to about 5 volts, Then if i add the 60A fuse the volts drop completely, I just cant find out what is causing the problem between the two and i cant find where they are and located in the car on the wiring diagram. Any help would be appreciated.
I have replaced a few fuses also (25,15) that look a little croded also.
