so last night i drove my car and everything was great (1989 TII). I went to go move it onto my front lawn because it started to snow and the plow would be coming and i noticed that my windows, wipers etc. were moving really slow like there was no juice..it also sounded a bit dead when i started it up.

the thing i thought was weird was that since the car started..shouldnt everything work fine at that point..i thought it was while the car was off that these thing would react this way(if a had a dead battery)

 

If your alternator is starting to fail (or has failed) the electrics would be slow, as the car would be running off the battery
