You have something going to ground taking out those fuses. I'd install all the old boards and then look for the human factor like pushing in on the car operating panel shorting the buttons and such out.

look in the bottom of the swing return and see whats going on with your power supply's, look for chafing on the traveling cable, check your switch tree, etc...

i'll get a DMC print and see if I can help your troubleshoot it.

what is between p24c and x06 ? what did you have to jumper ?
