Pulled into my driveway and the A/C, radio, and clock (possibly other things) all went out. Have replaced fuses and checked battery terminals. Checked 30amp breaker to see if it was tripped. Other places to look?
 
Seat belt light comes and goes while driving and I noticed that the voltage meter on the dash is a little low compared to normal. Replaced alternator several months ago.
 
Check the fusible link next to the battery. Specifically the crummy contact pins that hook it up.
 
Fusible links all pass the tug and continuity test. I noticed on start up that if I try to turn the blower fan on the seat belt light goes off. No idea where that connection would be.
 
Check and clean the ground cage holding the coil and ignitor too, that connection goes bad over time, and will cause electrical gremlins everywhere on truck. The 100s actually started adding a separate ground wire from ignitor case to body and block too.

Take a peek at the rotor too, that bad ground can cause damage to it too..
