New battery installed 8 months ago, radio is dead, something keeps draining the battery, are they related?

 

Simple solution, unplug the radio and check again.

 

Yank fuse 8 and 23 (if it is an 05) and you will have the radio powered down completely. If the battery does not drain after that, it's either the radio (fuse 8) or the power amp (fuse 23).

The faster way to find out is with an ammeter inserted in series with the battery ground cable - that will tell you what current is flowing and if it's too high, you can pull fuses until you find the one that is the key.
If NO fuse is the cause, you would then look at the heavy lead going to the alternator - a leaky diode in the alternator causes this as well.

Remember to raise hood, turn key off, remove key, close doors and trunk - and wait 180 seconds after connecting the meter (for modules to hibernate) - then, any current over 50ma (.o5 amp) is too much.

 

Thanks, turned out the radio was causing the drain, must have shorted out.Pulled fuse okay now. Still trying to decide if I want to swap it out for something nicer?

 

I had a smilier issue, but mine turned out to the the amp. I went through THIS site to get an oem replacement.

 

Nice prices. But since they are all used parts.................... meh.

 

Yeah I don't know if I would do a used radio, but when it comes to certain things like trims and such which I see are sometimes hard to find.

 

Yea, some parts you have no choice or option.

But used electronic modules? No. Used engine fan assemblies? Only if the price is LOW.

 

This is very true! I'm honestly just glad to see someone out there offering things that are getting harder to find.

 

If you are looking for a replacement radio I can recommend the Kenwood KMR-D772BT. I installed it last year, it was very easy with the wiring harness and an antenna adapter included from Crutchfield. It matches the XF silver interior, sounds much better than the OEM. Its a marine radio so it is also water resistant.
