New Battery and still foaming

Re: New Battery and still foaming

Sorry I dont beleive you unless the ONLY reason I stated regarding a bad ground. Either way, higher voltage would not cause the terminals to foam. Would you like a detailed technical explanation of how current is regulated? Lemme know I'm prett sure I explained the issue in great detail with a simple solution. I'm glad it'll help.

Nope, don't care to argue with you, the fact was that two voltage regulators failed, one from age and the second from a poor replacement part (the new regulator) and both times it caused an over voltage. Believe me or not, those are the facts. Replaced the alternator with a properly rebuilt and tested one and all's well.

To the original poster, check your voltages!

I'm sorry to hear that you believe learning is argueing. You could have taken this opprotunity to benefit your knowledge. Instead, you demonstrated ignorance for yourself and career. The fact that you neglect to accept the design of a VR prevents higher voltages is unreasonable. If you only considered the great number of solid state electrical components you would have to remove if the voltage spiked to uncontrolled values... eak.

Now again, I've never said the voltages couldn't be higher if there was a bad ground to the VR.

But you keep missing the second point to my discussion (i'm not the one argueing)... Higher voltage is not going to cause corrosion or foam at the terminals.

Re: New Battery and still foaming

I have seen cars that are overcharging and boiling the battery. Not the same as junk on the terminals. I have also seen those colored felt pads that have some red sticky stuff on them that claim to keep your terminals clean. I have not personally used them.

You bet! Except, there is no charging circuit in a car. The closest thing ppl confuse as a charging circuit is the diodes to remove any alternating current and prevent reverse flow. Overcharging occures when one or more of the cells within the battery are rejecting a charge with high resistance. That offloads the current to the operating cells. The operating cells begin to heat and boil. So, overcharging is fault of the battery not the alternator or voltage regulator.

Wow, from knowing NOTHING about me or my background you choose to think that I don't know anything or that I would actually miss the opportunity to learn anything from this situation. I did learn something. . . I won't waste my time attempting to actually share my experiences with you around, because obviously you are the expert and know it all. Besides you just insulted me for no reason other than the fact that I didn't take you up on you generous offer to "educate" me on the facts that I presented from experience. I don't really care if you believe me or not, it's not a point of argument, it's a simple statement of fact... Did you get that? I was relaying my experience, noting more, nothing less... Nothing to argue about. You think that I'm wrong in what I experienced and I said that I didn't want to argue, then you can assume that I added that I didn't want your knowledge on how voltage regulators work.

Now, I would tend to agree that the potential over voltage isn't going to directly cause corrosion or foaming on the terminals, but it's easy to check and might solve some other issues that he might be having. Now, if it is overvoltage and boiling the battery then it is possible that the corrosive vapors a collecting in the area and indirectly causing this "foam".

i'm not to sure why i'm bothering to post here but i will have to agree with p951. i have also replaced voltage regulators due to an over charging situation.

i don't expect you to believe me either, but just for fun, i decided to google alternator overcharging and found this related thread at #5 on the list. seems like we are not the only ones.

I didn't insult you. I called you on ignorance (please re-read your replies and recognize how you have come off that way). You are clearly missing the point that the high voltage issue isn't caused by a faulty VR. What I'm trying to get across to you is that it's another reason. It may be in the alternator, but it is _not_ the VR. I have no interest in anything other then sharing this particular bit of knowledge.

I don't gain anything by providing factual information to this forum.

Wow, again, calling someone ignorant isn't an insult?

Oh well, obviously you're right everyone else is wrong. No matter what real life experiences and facts of what I personally experienced it's not the voltage regulator, even if the only thing that was replaced was the VR and it solved the problem of the over voltage immediately. Since you say it's not it, then it can't be it...

I'm done, I have nothing else to add to this thread.

Re: New Battery and still foaming

I think Alienurv's point is electronics don't fail only surrounding/supporting connections will fail, accept it (in your case the voltage regulator didn't fail twice, it was a "bad ground"), and he will be happy.
