1gen Yota Electrical Issues

[StretchASU]

Recently I took my rig out for a run to try out my new tires. I was in the middle of climbing a hill when the entire truck shut off without warning. Now it isnt getting any bit of power from the battery, not even enough to run the warning lights. I have tried 2 other batteries with the same result and all of my fuses are good and grounds seem to be fine.

Anyone have any pointers or run into this same problem?

check the connection into your fuse box. 12 volts at the battery. 12 volts at battery and ground. 12 volts neg post battery to fuse panel there may be a fusible link smoked somewhere.
