Toyota Pickup Battery Drain................

Never use a fuse holder terminal to add devices.

I agree. She had this done around 95. I got the truck in 05 for doing some sheetrock work for her.

Kahrnut - I just checked the fuse and it was very loose. I tried to "squeeze" the holder and cracked a little bit of plastic to no avail. I then took out the 15A fuse and bent one leg one way and the other leg the other way and it is now working the brake lights! The "jumper" must have been creating the link to the brake lights and without it they did not work. With it it killed the battery! I am going to start buttoning everything back together.....


Thank you Kahrnut!

Nope... Didn't fix it. When the fuse allows the brakes to work the test light stay on. When I pull the fuse the light goes off. The "jumper" wire is out of the box and out of the question at this point. Still stumped!

If either one (or both) of the wires for brakes are plugged in it shows a draw. If I unplug one or the other it will still indicate a draw. I don't get this.

Got it squared away. Apparently the Cruise Control switch was on. Didn't know it, never used it and didn't realize it was a "constant on" for the battery. Looked at the wiring diagram in the Haynes book and realized the lead for the brake lights and the CC switch were the same color. I traced the diagram a few times with my finger and went to my truck, reached over and turned the switch off. The 12V test light on the battery then went off. I felt really dumb! I did however find a lot of stuff under my seat and behind it. Charging my battery now and got everything buttoned all back up.
