thanks, this is a great website, i need to check all the bulbs, i had to replace two and should have checked the rest, i know some bulbs are ok, when the truck is started the generator,brake,temp lights come on when the ignition switch is turned to the start position and they go off as soon as you let go of the key and the switch is in the run position and the engine is running.can you lose power to part of the panel or do you think its just some bad bulbs ?
