Disconnect the black battery cable, then the red one. Clean both the cable terminations and the battery terminals with a wire brush to remove all corrosion. You can also buy a spray to neutralize any acid residue. When the connections are clean, reconnect the battery - red first, then black. Tighten firmly, but be careful not to strip the threads. Finish by sealing with a protectant spray. Note this is a different spray, not the cleaner mentioned earlier.

When i open the hood on my 1999 jetta it smells of acid and their is white powdered acid all around the positive pole

I would replace the battery, but if you are unable to I would go to a parts store and pick up some terminal cleaner. That would take care of the acid build up giving you a better connection.

My 1999 Toyota Camry will not start all the time. The battery, alternator, starter all check out and I've had the battery connectors replaced. The dash lights come on when I turn the key. Oddly, when I...

-Possibly battery cable has not good connection between battery to starter. Or may be the cable itself is corrosion . (Keep in mind that outside look good but may be inside is fill and build with acid)
-Or may be the starter itself is worn out to the point not working as well.
-Check it out and replace it.

Good luck

Car won't start. There's no clicking sound but auto seat belts and some dash lights come on dimly.

Check the battery charge and also check that the battery terminals and clamps are clean and free of corrosion and acid residue build-up. If there are signs of acid or build-up, clean with boiling water only. Do not use baking soda or bicarb!

My car want start battery is fully charged. But the immobilizer light on the instrument panel stays on?

Having a full charged battery won't just solve the promblem. You might want to check with the battery terminal connection on the postive+ and negative-, It might be corroded, grease, or acid build up, so check for thse signs, also it could be that clamps are not fully tighten. You still can get power to the car from the baterry which in this case is leads to the immoblizer lights on the dash boards to stay on, but the terminal are corroded with acid, grease, or just from dirt, and with these element in presence, the battery is not fully ground. The engine needs a specific amount of amplitude from the battery for the engine to crank. A kia sorento v6 engine needs alot of cranking amp. So my solution is, check the battery connection terminal on the battery and the cable (positive and negative connections) de-tach the cable connections, clean the connection cables which are the adapter to the battery, and the battery terminals, with a toothbrush or high grit sandpaper until dirt, acid build up, grease are gone, and reinstall the cables. See if this will help.

First try boosting car with extra battery, attach posotive cable of booster battery to posotive cable of your battery and negative cable of booster battery to engine block, never to negative post of your battery, If it still does not turn over,Try turning over the motor with a socket and stong arm attched to crankshaft bolt. It could be that your motor has seized due to lack of lubrication

2001 suburban wont crank,clicks under steering column,battery is good,lights stay on,been doin off and on,but been 4 days.wont crank

Check battery conection first. Both posts on the battery terminal must be free of any debris or acid build up. Clean with baking soda and water. If it is the original battery then there is a chance that it may be going bad. You would still have lights but just not enough juice to start your truck. If the battery is new then the next thing would be your starter. Go in that order, cheapest first.

Will the battery connection to the starter cause

Yes when diagnosing this type of problem all electrical connections must be verified before condemning any parts. If all connections are verified and the vehicle will still not start test the battery, starter and alternator to determine condition.

All electrical is in- op

Sounds like a bad connection at the battery terminals. Make sure you clean the clamps and posts
really well. You can use baking soda in water to remove acid build up ( white powdery stuff ). Which
causes there to be a poor connection. If you have an after market clamp on one of the battery cables
take it apart and clean it good too. Also check the connection at the ground cable to the body and engine. Good luck. Neil W.
