When you put a new globe in the interior light I saw recently that in that type of globe you can get them in LED's in different combinations of of little light diodes so potentially you can make it bright enough to actually see something.
I was wondering recently about the switches for our wiper motors and the lack of speed that the wipers move at. Is this due to the wear and tear of any components or is this how they always were. If the switch lets you choose from slow or slower then would a different switch supply the wiper motor with more power so that it'd operate at respectable speeds. The switch is basically a two stage potentiometer I assume???
No the switch isn't a potentiometer, it's just a switch that selects which brushes in the motor will run the armature at different speeds, based on the position of the brushes.
The motor needs rebuilding to get it's speed back to where it used to be.
Armature machined and linished, brushes checked and replaced, the magnets re-magnetized, the gears and bushes cleaned of old grease, bearings etc cleaned and polished for smoother movement, and final assembly with the right tolerances adjusted.
Power is 12.5v, 13.8v, or 14.2v and that can't be increased by a grounding switch.
Rebuild.
