One of them is the water temp gauge. Went to mississippi from reno, nv and while climbing hills, the temp gauge would drop slowly to cold and the air from the vents would get cool/cold but while driving on flat lands it is right in the center where it should be.
The second problem is when driving with my lights on and the heater going or something other running, the lights would dim for a second when I stop at a stop light or going to idle.
With the power inventor on and running an electrical blanket or the tv/dvd player. The alt gauge would drop most of the way down for a second then up to normal. It would do that about every 20-30 seconds.
Would the two problems be a weak/old battery (may2008) or is it something like a voltage regulator?
I did check the alternator using a meter while at idle and it read 14.2
