I last drove my car Saturday and it cranked fine, but today with the key in the on position the dash lights starting dimming and the gauge needles were going on and off, and I could hear a clicking sound, when starting it does nothing, everything goes off, then comes back.

I checked the battery and the terminals were pretty warm, but I also noticed that there must have been a coolant leak from the overflow tube that got onto the battery, so is it likely that it just damaged the battery, or could it have damaged more than that?
Do you

THe battery is a sealed unit. Water, coolant. Won't damage it. Tell me, when you turn the key to the start position, does everything go off and then a few seconds come back on? Have you checked to make sure the battery is fully charged? Have you checked the alternator output?

What you described sounds like either a weak battery or most likely a bad connection at the battery. Make double sure the battery terminals are clean and free of corrosion and the are very tight.

Let me know

Thanks for your reply.

Yes, everything goes off and then back on, and the dash lights go back to steady then dim, with the gauges fluctuating, and the clicking, etc, but a few times the there was no dimming and clicking.

The other thing was until I cleaned the terminals there was some contact paste on the positive side and after it got wet it was puffing white smoke from the terminal when turning the key to start. The battery terminals were cleaned with a wire brush and I made sure they were tightened. I assume that was just the heat burning away the coolant, etc?

I am going to have the battery tested tomorrow to make sure it is still good, and check the charge.

I was just concerned that something else may have gotten damaged that would cause that.

Just wanted to update, had the battery tested, and they said it was fine but dead, so they did a deep cycle charge on it and a lot of water came out of it, but they still said it was good, so I tried it again, no luck.

Finally took the battery back to Walmart where I originally bought it, was still under warranty got a new battery, everything is good to go now.

Just wanted to share what happened with that situation, in the end it was the battery that was the problem.
