hello, I bought a P5 and it had an after market amp installed but it wasnt working in it. long story short there was a fuse on top of the fuse box that was installed and an amp that has a ground wire also installed. it seemed to work for 2 days but when i tried to start the car it wouldnt turn on because the battery was dead. i then removed the after market radio and waited a few hours. after i came back, when i put the key into the car lights came on but the engine was still unable to turn on.
im assuming that i have a parasitic draw from the amp, but im not sure how to test this. can someone please help me find the battery draw or maybe my battery is just old. if the latter case is true how would i go about testing a battery... does the auto store test my battery for me with their own meter?
thanks for the help in advance
