Reply to "Overcharging Issue: Toasted Voltage Regulator?"

lf-tp2511Member

Khan,

I just went through something similar with my battery.

After seven years, the battery in 2511, the same little thing that was there when I bought 2511, went south.

I finally found a correct sized replacement and installed, and then ran a voltage charging test like you did.

WOW! I too had something in the 17 volt range.

I made a quick call to Bosswrench Jack and we decided that with a new off-the-shelf battery, those voltages might be just fine, until the battery was fully charged.

Yup, after some driving time, the charging voltage went down to the correct range.

Now, bear in mind, this doesn't mean YOUR voltage regulator isn't broken...

For your questions:

stock alt is NOT internally regulated
yes, '71 'stang unit is fine

Finally, I do not like the mention of your battery hissing. Something may be wrong there. And yup, I'd guess regulator.

Do you have another, known fully charged, battery you could swap into the Pantera and run that test again?
