I was recently about to replace cable from solenoid to starter just the smaller one going to spade terminal connector anyways truck was fine before years before this week's and days before today however dead 100%. No lights outside or in dash radio door chime nothing. New battery new terminals same with another battery he'll even if I attempted to boost I get nothing anywhere. No signs of power anywhere all fuses check all seem ok from the ones I can visually check etc... Ideas? Something in the power block?
