There is a huge draw from my #21 fuse when the car is off. I checked all my interior lights, trunk lights, and my audio system, and nothing is on while the car is off. Does anyone know what else I could check or has anyone had this problem?

fuse 21 on an e30

With the key off, pull the negative lead from your car battery and place an ammeter between the lead and the battery post.

Anything more than a very small current indicates a short somewhere.

Next, pull and replace the fuses one by one until you find the circuit causing the drain.

Flashlight

Trunk Light

Clock and radio memory are always drawing power.

Later,
