So why the hell did battery acid spray everything under my hood?

White91TalonTsi · Aug 17, 2007

Well I walked 5K with 2 alternators in my hand to get them tested, wow that was hard. Turns out the one has a bad voltage regulator.

Threw my old (good) alt that was tested and I fixed the problem

On the drive though my cars not going into gear like at all and theres a loud whining and gringding when I depress the clutch...FUCKKKK DSM!

Sup guys, I justr put in a BRAND new battery today and terminals and has replaced my alternator about a month ago.

I drove the car around today on a hot day for about 2 hours applying for jobs so it was alot of driving..and it ran just fine. I park the car at my house and pop the hood to let it cool down a bit faster and I notice...WTF this cap from my battery is completely blown off and there is acid sprayed all over the top of the hood (Not a stupid amount but you can see where it ate the paint).

*This isnt my actual battery but one of those caps that say "danger poison etc" was blown off and I found it in the engine bay.

I have no clue how long I was driving it liek this BUT WHAT THE HELL IS GOING ON HERE!, car was running fine and had no voltage issues going on. I did notice my windows were rolling up extra fast , but AHHH What the hell.

I wiped up most of the acid with somewater and there is minimal damage but still help!!

You know this makes me begin to wonder about Interstate batteries. I work at my local AutoZone and just the other day a woman came in and her battery was doing the same thing. It was swollen so bad it was about to pop. Man I would suggest having your alternator tested to make sure its not charging too much and find another brand of battery.

I fixed the problem almost...its still at 15.1V when driving...overcharging still but not exploding battery tops...

Now my trannys fucked and I cant even drive the car and I have no money

This is why I run a mini Dry-cell battery...Well not really the reason but a benefit!

15.1v is still way too high, I wonder if the problem lies elsewhere (?)

The problem is still the voltage regulator off his old alternator.

I was told I just need to drain the battery alot (Its at 13.6V not turned on) and that fire it up and see where the alt charged.

But liek I said I have bigger problems now

You were told wrong. The battery should be sitting closer to 12v with the car off and not charging. That 13.6 is close to idle voltage so that's way to high for just sitting. Voltage regulator is fucked.

Voltage regulator on the car or on the alternator? (is there one on the wiring?). Ill fiddle with it somemore today...

The regulator is part of the alt. There is no fiddling with it.

As Rippin said there is no fiddling with it. In my previous post where i described what happened when my regulator went bad I forgot to tell the rest of the story.

I changed the alternator on the Probe and drove it again. Within 5 min it was doing the same thing again. I ended up taking it to a shop and there ended up being a short in the wiring that caused the regulators to keep frying.

Probably not what you wanted to hear but hope it helps you in the long run.

Samething happen to me.As it turns out my alt was close to shot, but still overcharging.I swaped the alt, and the battery stopped leaking.I put a new one in it anyway.No problems now.I say put a new alt in it.:dunno:
