Get your volt meter and test the alternator output... when it dies it often triggers the brake light too, not real unusual. If your not getting around 14v or more at the battery (engine running), your alternator is toast. If you are getting 14v at the battery (still running), most likely your battery is shot or you have a bad lead to the fuse box, that's doubtful though.

thank you very much

 

well its such a drain that with the key out of the ignition it takes about 3 hours to drain ..... it also gets around 14 volts at idle and when i rev it it gets about 17 volts so i dunt think its the alt .... also were is the fuse for the radio i hvae a gut feeling its that since ive played with it some

 

????????????

 

The alternator output should be pretty canstant between 14 and 15 volts max... the alt. has an internal voltage regulator that may be damged. Might be overcharging the battery, is there a rotten egg smell? If you suspect a short somewhere... start digging til' the problem turns up. The radio should have a constant hot and a hot in run connection, might have connected them wrong.

 

no rotten egg smell .... but i have no radio in now ... i also unhooked my front speakers cut the wires and wired the new ones in .....i dont have my back speakers plugged in could any of this be my problem ??? thanks to every oen who has helped me ... im a motorcycle mechanic so mechanicly im bright but as for electrical .....forget it if i knew were the radio fuse was then i could prolly take it out and eliminate my problem untill i hvae the time to reserch wireing diagrams on this truck

 

The radio fuse is in the fusebox on the drivers side... right above the kick panel. Should have a white cover on it that says wich fuse is wich.

And no, the speaker wires won't bleed the battery.

 

thank you very much well i looked for the radio fuse but on the white cover it has a map but doesnt show the radio but i also took out some fuses that i kno that i dont need and maybe that will help ... it kinda sucks b/c after i try something then i have to wait a day to find out if it works

 

Why do you have to wait a day? work?

 

takes about that long for the batt to run down .... but i found the problem .... it was my cig lighter that was messed up so i juss took the fuse out and i think its fine now .....thanks for the help flecker

 

you bet, new lighter from autozone is like $10.00.
