Re: Alternator question
One problem we have with our alternators is that they can be spasmodic... when on the way out, sometimes work right and at other times not. The voltage at idle can vary a bit with different components turned on and various "idle speed"... several variables even when no problem exists. Try to test it in a condition that is not normal for it if possible. If you ever catch it in the "act", there is no longer room for doubt.

The SVX has a high output at idle so you can run all your stock accessories on high and still not decharge your battery. To do that it needs to be putting out 13.2 volts. My NH650 motorcycle doesn't even meet the headlight and coilpack needs until it hits 2800rpm. Point is if an SVX alternator is below 13.2 at a normal idle speed (aside from the surge resulting in adding a new load which is gone in a second anyways) the alt isn't doing its job anymore. Assuming his battery is good and his voltmeter is good then 12.75 at an idle is below the minimum specs.

You're right Keith. There isn't an issue when an alternator is at 12.75.. My idle doesn't change a bit even with the ac on full blast and using the lights and wipers on. There is under no circumstance that you should be getting 12.75 volts out of an SVX alternator at a stock idle with a stock pulley with anything the car came with on. The surge you talk about is a temporary thing as the regulator is doing its job. It should and will in a properly functioning system return back to a normal idle once the surge is compensated for via the regulator. As for my shoulds and woulds that is simply providing what should occur in any charging system as many people who read this have other cars and apply knowledge they learn based on forums. You're right there is no need to be sorry, I simply don't want to see misinformation provided when possible. So show me where in an SVX charging system you should be getting 12.75 volts. I told you where you can find it in other types of charging systems but not on an SVX system. Happy New Year BTW!

Then don't send everyone on the form out to buy themselves a new alternator when theirs may be working normal! Happy new years back Keith Last edited by kwren; 01-01-2009 at 07:45 PM. |

Re: Alternator question
You need to rebuild your alternator or have something else bleeding the system. YOU SHOULD NOT HAVE 12.75 volts according to Subaru. Personally I'll believe Subaru over kwren as he already said we're too far away for him to come pick you up when you stop moving on that cold, rainy night 30 miles downhill from home without your cell phone.

If you are referring to some Subaru mechanic that probably doesn't know which end is up, simply test yourself on your SVX. By their own admission most will tell you that electrical is not their expertise. I naturally belong to AAA, the 150 mile one, as do all SVX owners. I always make a point to take my cell with me, even if it is just to go out the door to feed my dogs. So I am in pretty good shape cell wise. Again, simply perform the test on your own SVX. This is a no-brainer. Take care, Keith Last edited by kwren; 01-02-2009 at 11:33 AM. |

I don't and never have had AAA on my SVX. I guess I just take better care of my SVX then "all SVX owners". The only time that it broke down BTW was when my alternator failed. It was still charging over 12 volts at idle but didn't make it more than 15 miles in stop and go traffic.
