Voltage drop at ballast resistor

Ok, after all the madness I get it back together (except for putting that heavy *** seat back in) with no more then .5 volt drop anywhere, but my damn park brake light is out. I’ll be damned if I’m pulling that instrument cluster again.

Thanks so much everyone for the help. You’re all the best.
Could be the switch on the inside hand lever got knocked a little out of position. If it is the bulb, I generally find I can reach them from underneath without removing the panel. That's assuming no under dash A/C or othe junk. Find someone with skinny arms and hands!
