Nissan Repair: Battery drain, amp meter, aftermarket radio

Question
I have a '95 300zx conv. If I  dont drive it for 3-4 days the  battery goes dead. I only use it to go to work (5 mi. each way). I have a new battery in it. How can I locate the drain?

Answer
Chip,

Do you have an aftermarket radio?  If so, check the wiring.  If not, you can disconnect one system at a time and check for drain or lack thereof.  An amp meter is a good purchase and you can get an inductive type for about $20 bucks.  Place this next to the looms and see what is drawing your power.
