so i now own a 2wd toyota. (my first one) (it was free) lol

but anyhow i put in some new speakers and a new deck and it worked great. until i dropped my buddy off and back home. when i shut my truck completely off my charge light came on. (but was off when running).

so i spent a few hours trying to figure out if i shorted a wire or something i shouldnt have done. but no luck. so i checked voltage at the battery. only 9 volts. so i replaced the alternator and my charge lught problem went out.

ive never had this happen before. is this normal?

 

if your year alternator has internal voltage regulator, yes it is normal.

 

81 Would Be external

 

thats normal mine does that... when I put the key in my brake and charge light come one but go off when I start the truck... if your not sure let the truck run and use a multi meter to make sure the battery is sitting at about 14volts
