Hello from North Carolina!

Winters done and I'd like to disconnect my batteries and clean the terminals.
Any downside to this? I've had some cars that remember how you drive and adjust fuel/air ratio accordingly.

Will I need to do circles and recalibrate the compass again?

I've got 5 years on these and hope to get another summer out of them.

If you disconnect one at a time do all systems remain powered via the other battery?

If one battery dies will the other still crank the motor?

thanks y'all

 

Crank the motor, maybe if one is strong enough, but doubt it. Leave one hooked up while the other is getting cleaned. They are two 12V batteries hooked in parallel so one will keep all the electronic goodies happy if you leave one installed. You will still have 12V just half the cranking power(amps).

 

I know many people who only run one battery.

 

worst case you have to reset the time and your radio presets. I have an 03' and ive never noticed any other differences but the clock issue. Idk about the 04.5'. Just my .02

 

just reset the clock... everything else is fine.

 

They are in parallel, so you can do one at a time and not have to reset anything.

Just be sure you don't let that positive cable hit the frame or anything else metal or you will have a little impromptu arc welding going on.

 

Thanks guys, I'll get my wife right on it!

 

Disconnect away..... I do mine also from time to time.

 

I cleaned mine one at a time. No reset of anything. I just made sure the positive one I was working on didn't hit anything grounded and made sure I didn't ground myself either.

if you disconnect both at the same time, along with your clock and radio your trip meter will reset

 

I noticed my passenger side battery started to show some corrosion. I went to unhook the battery to clean the terminal and found one of the wires very hot. Hot to touch. It seemed pretty quick for that much corrosion to build up and I'm guessing this wire is part of the problem. I'm not sure what the wire is run to and if I can just unhook it and repair it with out doing anything special. The wire is a smaller gauge wire running down to a small black box. I didn't look to hard at it because I didn't have the right tools with me to fix it. Anyone else have this problem or know what it powers.
