K well I had my car in storage for the winter...so it wAs time to take her outta hibernation...thing had no power no biggie so I jump it an it fired up I let it run for a good 30min than go for a ride came to the end of my road an it stalls but wouldnt start back up....started rite up wit another jump..so I had alt checked it was fine so I bought a new battery didn't help so I bought a powermaster alt an changed ignition switch,and starter selinod and those didn't help shit wit the powermaster alt it says use a volt meter to make sure it's charging battery an that all checked out fine...so yesterday I try to start it and nothing but it wasn't dead volts were at9-10v lites work & everything so I jump start it took it for a 1hr ride everything was fine this was at 9pm...than this morning I try to start and nothing it has power but not anuff to turn starter....I'm lost I got a volt meter so if u guyz think I should test something let me kno any info will be helpful...it's like when the car is parked in the driveway something is draining the battery An it's draining it quicker than if I left my lite on
to check for a power drain ...... get a 12 volt test light ( they are cheap ) disconect the negative battery terminal .... make sure all power accesories are off , and the doors are shut , key must be off, if it has a hood light disconect it . Now with the negative disconected from the batt..... attach the test light between the neg. terminal and the neg. side of the battery post . the light should be very very dim or off . If it lights bright you have a power drain . At that point you will have to start pulling fuses one by one till it goes dim or off . then you found the suspect circuit .
