My gadget has a corroded battery terminal. how do I fix it to recover files?

Did you check the metal pin and spring terminals the batteries sit between? If a battery powered toy is stored with the batteries still in the terminals can corrode and block the electrical current from the batteries. Try cleaning the terminals with a cotton bud and Very Fine sand paper. A cardboard nail file works well for this.

That can be the sign of corroded battery terminals or a dead battery. Check battery voltage at the posts, no the cable terminals. IF it's above 12.2 volts, clean the posts and terminals and see if that fixes it.

Yes, you can replace the cable end.

The can be caused by something as simple as corroded battery terminals. Check them first. If they are all crusty clean them and reattach them. I spray mine with white grease to keep them from corroding again.

If that doesn't fix it check your battery. Take it to a shop with a load tester. They will do this for free because if it's no good they will sell you a new battery.

If you battery is good and your terminals are clean then check the alternator.

I have driven these cars for years and have never had an alternator fail. It's always the battery or terminals.

It is true when people say that the millennial generation is inseparable from their gadgets such as android phones, laptops, music box. This is all because of the hole in our lives that our gadgets fill is huge, the role that they assume in our lives as employers, employees, teachers, students and even as members of our families somehow surmounts anything that has ever been invented.

No clicks at all? Does it even crank over? Maybe you blew the fuse going to switch. Check all connections where the + side of the battery go to. Is there something corroded? Did you clean the terminals good when you put the battery in? Sometimes things will work that draw a light load, but when you try to crank it over it will lose connection. That is all the things I would try.

The negative cable from battery must go to body/earth
If you connect to engine you will have no decent earth for electrics as engine has rubber mounts
Is your corroded terminal causing problems,if not pour boiling water over,let cool,remove and clean.apply terminal grease

I removed the battery terninals from another remote control and used them to fix the Sansui remote.

Get under the hood and start shaking the wire harnesses, while you have someone sit in the truck waiting for things to flicker on and off. Chances are good that you have a corroded connection that supplies quite a few gadgets. Also check the terminals coming off the battery, and any smaller wires attached to them. These frequently corrode faster than the larger wires. By the way, shaking the harnesses...is called, " THE WIGGLE TEST". Good luck. Chip
