Default Battery light ON, E-Brake light ON. Low charge

1997 D21 132,000 miles
All happened at the same time. E-Brake engaged light went On, Battery Light went ON, and also at the same time, unable to read trouble code through that little dongle plug in thing - no power to that.....Hmmmm.

I checked the battery, it's OK, and it took a charge from battery charger.
Alternator was charging at about 11.4 volts, way low.
But it happened at the same time as the brake light going on.

Are there any fuses of issues that might make sense on this situation?

It’s your alternator. Classic failure symptoms.

Any opinion on decent replacement. I generally buy through Rock Auto.com

In checking things I also note that one or two of the bolts for belt removal and belt adjustment( to get to alternator), well, looks like the previous owner rounded the bolts a bit. What's the trick to getting them undone? And how would I locate replacement bolts?

And thank you for your guidance and advice. It is much appreciated.

Vice grips should assist with the rounded bolts. David29 is the parts man around here. He probably has what you need.

As far as the alternator brand? I prefer to use a local parts store. The alternator is a gotta have item, and I don’t want to be waiting and playing the mail order song and dance for a part I need as soon as it dies.

But now I have a third vehicle, so I’m not driving the truck as much. Seeing how I have a spare mode of transportation, I would probably get a rockauto one to save a few bucks I guess it boils down to how bad you need the new one..

If you’re gonna go with rockauto, I’d get the Power Select brand since it’s the only one that is described as 100% new. Reports of bad remanufactured alternators are common.

Disconnect the battery before you get started.

For removing the bolts...depends on how bad they are messed up. Once you get them out you MIGHT be able to get a suitable replacement at the parts store. Depending on the resources available in your area, there may be a business that specializes in fasteners. Like Fastenal.

If neither of those are options, the part number for the long adjusting bolt is 11717-V720A. The short bolt is 08126-8451E. And the bottom bolt is 08174-0071A. You can get them online or from a dealership. I’d recommend using your VIN on some of the parts websites to make sure I got those part numbers right.

Thank you very much.

I use Rock Auto because a parts store about 2 miles away sends out parts for Rock Auto and they always seem to have stuff in stock for me.

I got the same scenario after power washing the engine on Fri. Hope it dries out and goes away. The alternator isn't that old.

I have the long bolt that adjusts the tension on the belt. These are new items. If thats the bolt you need, private message me. I can ship next day after payment.
