does anyone know what my problem is?
this morning i had to jump start my car i thought i must have left a light on or somthing. but on my way to work i look a my volts on the PFC while i'm at a stop light holding my breaks my volts are reading in the 9's. so i had to hold the break and gas to keep the car running. then i get to work and try to restart to see if the battery is charged but it wont start. after another jump start and pulling it into the shop it wont even jump start again. my new condition

check battery with multimiter 12.3 volts
turn key to on position int lights,guages,pfc commander work
try to start car and all goes dead and the main curit relay ticks like crazy

check battery again 12.3 volts
turn key to on position int lights,guages,pfc commander work
try to turn on head lights and all goes dead and the main curit relay ticks like crazy

is my relay bad? how can i check if its good?

the condition seemed to get worse and nothing works now i cant even jump start the car. i'm tryinig to get tuned soon so this sux. thanks for any help

 

Sounds like a bad alternator to me, if you ever get it started again, check the voltage out of the alternator, it should be in the 13.3 range. other than that, check the grounds for the battary. Also you might want to check the starter and make sure everytime is tight.
