2G Radio turns off when I pull interior light fuse.

[Jacolu3]

Is the radio suppose to lose power when you remove the fuse for the interior lights? The fuse box under the hood has a fuse for the radio and a separate fuse for the interior lights. If I pull either one of them the radio shuts off.

So quit pulling the fuse if you want radio . What are you doin messin around in there anyways?

 

[luv2rallye]

Yes the interior light fuse supplies backup memory power to the radio (to remember station presets and clock).

 

[ThunderChild]

And the radio fuse is for acc. power to tell it when to turn on

 

[Jacolu3]

I had and probably still have a battery drain when the interior light fuse is installed so I removed it so my battery didn't die. So I've been just driving around with no radio

So if this is true than removing the fuse I shoujd just lose the presets but the radio should still work?

Is it a stock or aftermarket radio? If aftermarket, it could depend on how the radio was wired up. I'd suggest pulling the radio and matching the wires to be sure it's done correctly.

 

[Jacolu3]

It's an aftermarket radio. I'll have to pull it and confirm the wiring

 

[Dragnous]

I would double check the wiring and check to make sure its grounded correctly as well.

Here is how they should be hooked up:

You can always wire it around that fuse if you need to.. But figuring out why youre getting drain would be better than pulling a fuse.

Thanks for the link!!

When I first got the car there were wires everywhere. Really was a nightmare trying to clean up the mess. The first day I had the car I removed a ton of wiring with more to take out. Here's a pic of some of the excess wires

When my fuse was blown I only lost backup power so the radio always stayed in demo mode. The radio should work fine otherwise; if not you probably have your power wires mixed up.

If it's an aftermarket radio just tie the yellow and red wire together and run to the accy wire of the car or red at the harness you won't keep memory for the radio but will still work and then you can pull the light fuse

 

[Jacolu3]

Cool thanks for the info!!

I wouldn't wire it like Denvario said, if your going to pull all that crap out and fix it do it right.
Yellow needs to be on a 12v constant, so use a test light and find a wire that has power with no key in/acc off. I found one in the old radio harness.
Red needs to be on a 12v accessory wire, I spliced into one from the cigarette lighter.
Personally, I always ground extra connections to the chassis/metal itself instead of splicing into the wiring harness. This prevents any extra load from causing issues. There are several bolts on the left and right of the center console (under the access panels) that are good for this.

Your going to have to find this battery drain someday anyway. The room fuse powers more than just the radio and dome lamp: http://www.dsmtuners.com/threads/10...-fuse-draining-battery.424216/#post-152856627.

Here's how to find shorts and battery drains: http://www.dsmtuners.com/threads/finding-a-short-partial-short-or-battery-drain.179481/#post-1496998

Cool thanks for the info everyone. I'm going to have to spend some time this weekend.
I'll keep everyone posted

Car electrical systems is what I do for a living he could bypass the circuit as said above and have no problems at all other than that circuit not being powered causing whatever else on that circuit to not work... Test light won't tell him where his parasitic draw is coming from he needs a Dmm digital multimeter a cheap one from harbor freight will do just fine... Switch your red probe to 10amp plug switch to amperage setting remove the battery cable place meter in series with the battery and the cable removed anything over 150milamps is too much period that will include anything aftermarket ex. Alarm systems, etc if you read that it's higher or there is a draw start pulling fuses until you isolate that circuit then start unplugging equipment on that circuit till draw goes away and you will find the culprit ...

 

[khmersun]

you could run fused wires from ur ignition please test and verified but for some eclipse 2g
12 volt constant at ign is white
12 volt acc at ign is blue/black

 

[Jacolu3]

Finally got a chance to test some stuff out today.
Pulled the radio and the ground is going directly to the chassis with a stake on around a bolt and I tested it and the ground is good.

Now with both fuses installed (radio and interior lights) the yellow wire has constant power and the red has power only in acc.
If I pull the radio fuse I lose acc power (red wire). But still have my constant (yellow).
If I pull the lights fuse I lose both acc and constant power.

So not sure if this is correct or not. Any input would be greatly appreciated
Thanks
Brian

Also I might have corrected my parasitic draw when I removed sold alarm system and just never checked. I just checked my draw and I'm getting 30 milliamps which I believe should be fine. If I remove the interior light fuse I get 10 milliamps. Don't think that an extra 20 milliamps should drain my battery.

 

[Denvario]

Any draw will drain the battery eventually but a small draw will take a long time to do so if it's below 150ma you are fine for perspective a alarm led flashing draws 150ma. The interior fuse should be the constant 12v source for the radio only not accy as well something is not correct

 

[Denvario]

Radio fuse accy power
Interior fuse constant power
