Think My Voltage Regulator Died...
Posted 12 March 2004 - 11:58 PM
Got going off a stop light, and I noticed that the heater blower sounded a lot louder than normal. Glanced at the voltmeter on the gauge... 'bout 17 volts. Let off the gas, and it settled back down. Pulled into a parking lot, rev'ed it up to 3,000 RPM's, and it launches up to 18V. Blower motor rev's right up along with it, and the dash lights get brighter. Didn't notice whether the headlights got brigher, though. Let it idle, and everything's fine.
Proceeded to drive back home, trying to keep the rpm's under 2,500 (the point where that voltmeter needle starts to climb). Yeah... sluggin' around under 2,500 RPM's in a Subie is not fun.
Anyhow, I figure that means my voltage regulator is toast. I suppose I could verify it with a voltmeter, but I figure the blower motor and the dash lights corroborate the theory well enough.
A quick search 'round the board says I could replace just the VR, but it'll be a lot easier to yank the entire alternator. Makes sense to me... I remember fooling around with bushings on an old generator. Not fun.
I'm going to take a look at the local junkyard, and see how much they're asking for it. I need to pick up two tires, too, preferably with the 13" rims along with 'em. What's a reasonable j/y price for the set?

oem alternator runs about 70$, if you need to take that route.

Took it out, ran it up to Autozone, and had them test it. Under load, it'd put out 19 volts... when not loaded, it went above 22 volts and off the scale.
They wanted $55 for the new one... I grabbed it, slapped it in, and now that voltmeter is steady as a rock. Life is good. I'll pick up the tires towards the end of the month.
