i have a 66 200ci mustang coupre. my battery kept dying, so i had it tested and they said it was a bad battery,, so i bought a new one, put it on. didnt drive my car at all, and the next day it was dead. so something is draining the battery, i dont think its the alternator because i didnt drive it at all and it died. i have a high quality alarm, but ive had it for a couple years with no problem.. just recently the where u put the key in the ignition got jammed,, and its difficult to work the key in and out.. so maybe its staying with ignition on.. is there any way to check if ignition is on.? cuz with the car off i can still turn the signal lights on. is that normal for that car, i never noticed?? but please help i need the car next week for school.!
