Baking soda will nuetralize the chemicals, but will not clean the contacts sufficiently. You will have to use a fine grit emory cloth or knifeblade, or similar abrasive material, to scrape the compromised contacts, until you get to fresh, uncorroded metal underneath. This will usually restore the unit, and make it operational.
Also check that the switch is good for the light, since they can become oxidized also.
If you're good with a voltmeter, you can ohm out the wiring, or troubleshoot it to find the problem.
If it's a switch, it's usually a swivelling metal contact, so make sure it's clean and making a good connection.
Good luck, and hope this helps.

What's your question? hi if the wire leading to the positive terminal of the battery gets corroded by battery acid can it effect the car in starting. ....

Most certainly. If battery acid is present on top of the battery, the seal between the post and the top of the battery is leaking. Replace your battery and use baking soda and water to clean the battery cable.

The only way to fix this problem, is to bring in to the place you bought it and see if they have a technician who can look at it or do it yourself.
I can tell you that whenever batteries are left in any battery operated device and corrosion happens, that corrosion will leak into the circuit board and destroy some of the components.
If you are lucky, you can open it up and clean it.
Just be careful when openning and do not use a solvent in it, unless it is one recommended for cleaning circuit boards by an electronics technician. The cleaners some technicians use are not even for electronic, but have been tested on delicate circuit boards and have been proven to be safe.
Ask someone like a geek at best buy or some other shop to find out what to clean it with.

How do you change battery

Same philosophy regardless of vehicle or equipment.
CAUTION! Battery contains acid which can also be present in general area. Take appropriate precautions.
1) Dis-connect Negative terminal.
2) Disconnect Positive terminal.
3) Remove battery hold down brackets
4) Remove battery from vehicle. Rinse hands to make sure no acid on them
5) Clean terminal connections (battery post clamps). I use a weak solution of baking soda in water and soak the clamps until the foaming stops, then rinse well with fresh water. It's a good idea to rinse the battery tray with the baking soda solution and then water before installing the new battery.
6) Place the new battery in the correct position in the vehicle.
7) Re-install the hold down brackets.
8) Connect the positive cable to the positive battery terminal.
9) Connect the negative cable to the Negative battery terminal.
10) Start engine to check.
11) All done, Make sure the hood is closed.
12) Nap time.

Battery exhausted

A solution of baking soda and water will neutralize the battery acid. Use a Q-tip soaked in the solution to carefully clean the contacts. Do not allow the moisture to leak into the camera's interior. Once you have neutralized and removed as much of the acid as possible, carefully polish the electrical contacts. A clean pencil eraser should do the job, but you can also use a small piece of extra fine emery cloth to clean the contacts until they are bright and shiney.

I have an Optimus wireless headphone device. The battery pack gets constant corrosion it causes the battery to leak. Bought it at Radio shack but they said to contact the parent company which is Opti

only one way to really stop that, someone has to get it apart and scrape all the stuff off the battery contacts (I use a knife and even a small file and then use baking soda to prevent the return--you can use a car battery spray made for this or even tranmission fluid will do it. once clean and protected (especially clean the contacts where they touch the battery) keep a eye, what happened is a battery was left to long or on way too long and leaked on the contacts.

2006 Roadster1200 , no start condition. signal and warning lights flash only. what to do ?

I would start with the battery and battery cable connections first.

See if the battery is at a fully charged state. You may have to remove it, and take it to the nearest auto parts store for a load test.

Before you do check the battery cables. More specifically, the battery cable ends on the battery. If there is ANY corrosion present, 'juice' from the battery isn't going to go through. Doesn't take much with those small battery ends. (Turn signals and warning lights don't take poo for electricity to light up)

Clean the battery cable ends, and battery terminals if corrosion is present.
It's best to remove the battery, and clean it. Otherwise the cleaning solution will get all over your Harley, and can be the pits after it dries.

Use old clothes when you do this, wash your hands thoroughly when you finish. DO NOT touch your face or eyes until you wash your hands! DO not use 'Coca-Cola', and watch using baking soda/water solution. Use the solution with caution, because if it gets inside the battery, it will render the battery useless. Be sure to rinse the battery top well with cold water, to flush any remaining residue of baking soda/water solution.

(Baking Soda/Water solution:
20 ounce old pop bottle with 2 tablespoons of Baking Soda, and warm water mixed well)

The second place to look is the battery cables. (You have a separate wire from the Positive battery post for warning lights, etc. You need to look at the main battery cables)
Turn the ignition switch, and turn the headlight on. Is it bright when you turn the headlight to bright?

Suspect the Positive battery cable first. Then the Negative cable. [Check the connection for the Negative cable to the bike's frame. Is it tight? Is rust/corrosion present?
Is the Positive cable connected tight to it's connection?]

Then I suggest you have a starter problem. (Starter solenoid, or starter)

[Usually turns out to be corroded battery terminals, and battery cable ends, though for your problem]

Need directions to clean my tappan oven

1. Add baking soda to a cool oven. Sprinkle a thick layer of baking soda onto the bottom of the oven. Make sure the oven is completely cool before you attempt to do this. 2. Spray the baking soda with water. Using a spray bottle, spray the baking soda down until it is damp, not saturated. The water and baking soda together will help break down the food particles. 3. Continue spraying baking soda as it dries out. Every few hours spray the baking soda down again to keep it moist. Continue this process over several hours, spraying water as the baking soda begins to dry out. 4. Scrape out the baking soda. Scrape the baking soda out of the oven. Food residue will be scraped out with the baking soda. 5. Rinse the bottom of the oven out thoroughly. Yes, you'll still have to rinse out the oven, but next time you cook your food won't have an added taste of oven cleaner.

If I had the rest of your model number I may find what Tappan now Fridgedaire Electrolux reccomends, but this is the least toxic. Have a great day..
