When I turned on my rear defroster tonight..the headlights dimmed and the ampmeter took a nosedive...I shut it off and everything went back to normal? Gonna look at the wiring tommorow...bad switch or bad ground to the defroster?
 
Defroster may be working just fine. I would start looking to dirty and/or bad battery clamp, bad battery itsell,
It should also be slow or hard to crank with a bad or low battery.
lose alt belt (it generally squeal if lose), Weak ALT.
If battery checks out OK. I think it would be a bad battery to body ground or engine to body ground.
But always check you battery/clamps first with any low voltage problem.
