Just a short little story about last weekend. Sunday AM my friend and I climbed Mt. Adams in Washington. We got up at 11:30pm (saturday) and began our hike from the trailhead at 12:30am (sunday). Round trip it was ~12mi with near 7000' elevation gain. Conditions on the mountain were beautiful and we got a fantastic sunrise from the false summit.
For me the real adventure began while driving the extremely washboarded road out from the trailhead. Somewhere along all those bumps the battery light came on. I immediately shut off everything I could: no AC, no radio, no lights, no ham radio. The battery light indicates that the battery isn't charging correctly. The odd thing was that at idle and in neutral the battery light would go off and a tiny charge would take. Regardless, the voltage meter was dropping fast as I drove and coasted down the mountain. I somehow was able to milk it enough to reach the Autozone in Hood River, OR. The battery died right as I pulled into the parking spot out front.
So now I had to figure out what was wrong and how I was gonna get home to Beaverton, OR. I pulled up this forum on my phone and everything points towards a bad alternator and/or battery. Again, there's a tiny charge on idle, but if I rev it the battery light comes on.
The AZ guy gets their battery/alternator tester out and it shows a bad battery. Well duh the thing is dead, I just drove it with no recharge. It's a 4 year old battery and I was planning on replacing it soon anyway, so upgraded from a 750 CCA to an 850 CCA because why the hell not. I fired up the car and give it a rev. Still getting the battery light. AZ guy thinks maybe the belt is slipping.
He rings me up a new belt and hands me the tools to install it. Boy howdy, I don't mind working on my car, I just wasn't planning on doing it after being up since 11:30 the previous night. Using autozone's tools I get the belt replaced (much easier with my home tools!). I fire up the engine and still get the battery light when reving. Oh well, old belt was starting to squeak anyway.
Well the only final thing to look at is the alternator. I catch my breath and take a moment to watch this wonderful how to video on alternator removal/ replacement: .
Tired, but feeling confident that I could get it done, I remove the alternator and take it into the autozone. They match me up with a 130amp replacement. I get it installed, fire up the truck, rev it... NO BATTERY LIGHT! I cheer with joy as I slam the hood down. I go in to return the tools and the AZ employees are all smiles: "We heard the hood close!" They even let me wash up in their bathroom. With the truck running, and me being tired and happy, I hit the road for home.
If you're ever in Hood River and need something, the Autozone there has great customer service
Now time to buy an extendable ratchet to keep in my truck...
