What is connected through the audio fuse in the engine bay, fuse box by the battery? I've narrowed it down to that fuse... And it just barely started

Halp?

 

That fuse supplies power to 2 things: the radio to keep the station preset memory active, so there is a small power drain all the time. That fuse also powers another part of the audio system but exactly what is powers depends on which audio system you have.

In the Bose system, it powers the speaker amplifier. This should not draw any power when the radio is off, but of course a defective unit could. Unplug the wire harness from the amplifier and see.

In the non-Bose system, the fuse also powers the optional 4 disc CD player. Unplug the wire harness if you have it.

 

I unplugged my sub... I forgot I had the damn thing, since it has cut out completely now

I'll let you know my readings tomorrow

 

just disconnect your negative battery terminal, get a DVOM, set it to amps, put one lead on the disconnected battery cable and one on the negative terminal. max draw can be 50 milliamps, anything more is parasitic

if you get a high reading with your sub plugged in, but the reading goes way down when you unplug the sub, you know thats the drain

you can use a light probe tester as well, HAS to be one with a incandescent light in it and not a LED, LED will not dim the light so you know when the draw goes away

 

Alright... So with the audio fuse out, and my interior lamp fuse out... it reads about 21 milliamps

With just the interior lamp fuse in, it reads 98 mA

With just the audio fuse in, it reads 280 mA

With them both, it reads 350... I don't have time to look in to it more now, but I will tomorrow

 

And that is all with The Bose amp and sub disconnected
