electrical issue
so ive been having a problem with my electrical system. i did the fuse pull test and nothing changed. i replaced the starter thinking the solenoid was the problem. there is a blue spark when attaching the ground to the battery and cant figure out where the draw is coming from. im at a loss right now and would not like to take time off work. i have an alarm system but that shouldnt be enough of a draw to drain the battery. i have a relay for my hids and that didnt change when i disconnected it. i have a kill switch for my amplifier but thats tapped into a 12v constant and isnt sending power to the amp until the switch is on. so if anyone can shed some light on this i would appreciate it. hopefully mdtahoe or maxx will speak up. thanks in advance.

Disconnect the negative battery cable. Take a DVOM (digital volt ohm meter) put the positive lead on the battery and negative on the cable. Set the meter on mA (milliamps). What is the reading after 1 min, after 5 min? Any other way to check for a draw is wrong, unless you have a low amp clamp. It needs to be around 30 mA (0.030) or less.

interior light, cargo light, underhood light. does the toggle for amp light up? have you added any other electrical things? how old is battery and have you had it tested?

no lights are on. the toggle switch for my amp does light up and i turn it off every time. ive added interior leds and that is wired to my ignition. the battery is stamped 03/09. i have not had it tested.
