Y'all have any idea what would cause my truck to overcharge, to the point of spewing fumes, my secondary battery? It only happens after I've been running at highway speed for a while. It's getting expensive fast!

Thank you! I thought there was a fuse between the regulator and batteries!
I'll go get a regulator. Can you help me understand why the secondary battery bore the brunt of the failed regulator? I don't get it.

Corrosion would be my guess. Older cables oxidize and require more voltage/amps to jump through. That applies to the grounds too. I replace cables routinely and always use di-electric grease on the connections.

X2 on the regulator, mine's charged at 16.5 since I got it, but I just keep the blower motor on high and run with the headlights all the time to keep it in check, keeps the voltage at 14.6

When you install that voltage regulater disconnect the batteries first. Then plug in the regulater. Then connect the battery. This trick cost me three regulaters long ago. The mom & pop strater & alternater shop told me what I was doing wrong... Sure huff worked.. I asked why this was happening.. Just shrugged his shoulders saying "it just happens sometimes like that".. Lesson learned...
^^^^ What He says....HE KNOWS HIS *****! ^^^^ Seriously I've heard/known this too for quite a long time...IIRC Bill my friend told me back in the 80's

Al... Your imbarrassing me... I had to be told about this once also. But passing it along so others are on the same page is what this forum is all about... Now if someone reads this.. Then comes here whining about burning up a regulater asking for help... Well I'm gonna tell them to go play leakfrog with a unicorn....
Thank you gentlemen! The regulator did the trick. I truly appreciate the help and advice. If you find yourself in/around Denton, Texas let me know, I'd be glad get is a round of beers.
Glad it was a simple fix.
That goes for saying with ANYTHING electric on a vehicle. Pull the batt cable first. Folks get a bit lazy because older vehicles tend to be a bit more forgiving and you can tend to get away with a lot of things on them a number of times...... before bad things happen. If you were to be working on newer computer controlled vehicles the first step is ALWAYS to remove the battery cable and to make sure to follow anti static procedures just as if you were working on a giant friggen rolling computer, when servicing ANYTHING on their fuel or ignition or emission systems because, well basically , you are.
I do love old diesels
