It used to happen every time I started the car, my Eclipse deck would reset itself, lose all the radio station presets, etc. The clock in my dash never lost the time, however.

I found that my negative battery terminal wasn't completely tight, I tightened it and that seemed to help. But now the problem is back.

What could it be?

just wire it straight to the battery and u will never have the problem, end of story

 

low capacity in your battery? could be when you start your car, the cranking power is lowering your voltage to a low level?

maybe a bad connection from the neg batt terminal to chassis.

 

some cd players have a battery in the deck itself, and if that dies that will happen.

i dunno why that is, check ur manual see if it has one, if not try grounding the cd player to some metal, not using the cars black ground cable.

if you already have it like that, try wiring straight to batter like he said

Cool thanks guys, I'll try and tackle the problem with this advice.

Dan

 

u didnt connect the memory wire. u hafta connect that to a constant thats hot when the car is off. get a tester and find a wire and just splice...OR connect to battery, your call.

 

Um, there isn't a wire labeled anything like that on my Eclipse deck.

 

It is the yellow wire, let me ask you this, do you lose memory only when you start the car or do you also lose it if you just turn off the ign. and then turn it on, without trying to start the car, eg. if you get in the car in the morning an just turn on the ign., [do not try and start the car] has the HU "reset itself" or does it not do that until you try and start the car? 94

 

It only does it when I crank the starter. Not when I turn it off, not when I turn it back "on." And it only does it sometimes. I'm thinking it's a weak battery, since it doesn't seem to do it after a long drive - only after the car has been sitting for a while or has had some drain. My next move is to have it tested, I just gotta get off my *** and do it.

Dan

 

Yea that does sound like a batt., [low currant] problem. Most places that sell batt./alt. will do a check for free.

Also, because the oem constant power in the oem radio harness was only for memory for the stock HU, in most cases there is not enough currant there for today's aftermarket HUs, what we do in our shop is run a fused 10ga or 12ga from the batt. to behind the HU and connect the constant power, [yellow] to it, just like you would do to power an amp. 94

 

Can do.

 

im telling you partner... chances are its a weak battery.... i had the same exact problem. I have the CD3434 and my deck was losin power because of a weak battery that couldnt get itself out of maintinence mode... you either need to charge to get a new battery otherwise you will have this problem all day...

 

or carroded batt terminals disconnect them and clean with wire brush the batt post too if it still dose it than its the batt

 

Good idea; the battery terminals are clean though. I also have a reinforced battery-&gt;chassis connection.

 

Your wiring is bad
You wired the 12v Lead to the Ignition wire
and then the ignition on the deck to the 12v lead

Pretty easy fix.

 

Just an idea - do you think the draw from my amp is causing the battery to charge slower on short drives? It's an Eclipse that's fused at 50A. I don't crank it but sometimes I turn it up a bit.

No it shouldnt. But check you fuse that goes to your amp. If you have one you should just run a big 30a fuse. Just run a wire from your batt. to the head unit. If theres a problem after you do that then its the hu.
