I have two problems I'd really like some assistance with:
1. Brakes...When I mash the brake pedal and release it, the pedal doesn't
come all the way back up to the top. It stops about an inch from the top,
and stays depressed just enough that it leaves my brake lights on. (Ran my
battery down Monday!) Is there a spring of some type that pulls the brake
pedal all the way back up to the top? If so, where is the spring located
and how hard is it to replace? If that's not the issue, what else should I
check?
2. My headlights get brighter when I rev up my engine. (Brighter than at
idle.) My truck has been converted to 12 volts and has an alternator.
Does
this mean the alternator is not working well. Or...is this normal and no
problem at all?
Many thanks for your help!

Tom,
on #2 above, Alternators typically do not produce much current at low
rpm's, and if there is much current use, the system will drop to battery
voltage (11.2 -12.1) when the alternator is really spinning, the system
voltage should be about 14.3 at the alternator output terminal. If your
battery is getting tired, you will see more system voltage drop at idle
(you may want to check the battery condition) but some dimming at idle is
typical.
