A recap for others that have similar problems. Batteries weren't getting a proper charge but alternator seemed to be working so after numerous talks with mechanics and forum folks, it was most often guessed the regulator was the problem.
After taking the vehicle to two shops in town, one an alternator specialist, we found that to be the problem. Our dt466 diesel international had a relatively new (6mth) old alternator which has the regulator inside. The alt was a "private label" from International, which we were told by a Int dealer this particular one tends to have regulator failures.
Replacing the alt with a brand new one fixed the problem of it sometimes not charging the batteries or charging barely enough.
Good thing for us is the alt was under warranty so total cost to replace was $30 (loved that...no full hour rate charge), took 15 minutes.
Hope this helps others with similar problems!!
Hello everyone! I've ran into a weird problem with Fran. She's sat for about a week and temps here are 50's days, 40's nights and we're on the coast about a mile from the ocean.
Went to start her and the beeps that go off while warming up (glowplugs) before cranking the engine were not the usual noise but a higher pitch beep. The voltage gage (think that is the name) says she's at 12 (black area) when she usually sits just over 14 (green area). She did start without a hitch though, ran her for about 15 minutes before turning her off.
Too scared to drive her as we're living in her, so if she breaks down I have to get a tow and not sure the campground we're in would allow us to sit here with a vehicle not working. Sure can't afford a mechanic at the moment.
Any suggestions on what the problem might be? What to check for, clean, test. The alternator is brand new this summer. Battery cables are a bit old but seem in good enough condition. One battery is new, one old (yeah I know... shame on me). Suggestions, please
