voltage regulator?
 

does the SVX have a voltage regulator? Or is that built into the alternator? I'm used to working on older cars that have their own control for it. If it's built into the alternator, what do the wires coming off the alternator goto? Other than the top one that goes to the battery

It's built in....
 

and uses an IC regulator and a couple of silicon diodes to rectify the AC to DC

how would I know if this went bad?

Most of the time when a voltage regulator goes bad it will overcharge your battery and cook out all of the fluid. Not good.:(

eh, doesn't sound good to me either. How could I test for that though...Recently I've been having my lights dim for a second, then come back to full power, every now and then it will almost be like a flashing effect with the dimming....

I've also noticed that my inverter powers down then comes back up and a min or 2 later does the same thing. My radio and amp dont shut off, the only hint of a problem is the inverter, and that i can see the normal driving beams dimming in a pitch black area, along with the gauge faces...oh, and those warning lights dimming in and out...

If the reg goes out, it won't charge at all, it's output feeds the field winding, no reg output, no charge.
If the battery voltage goes to over 12.5 volts, usually up to a max of 14.7volts, when the engine is doing over 2000revs, the reg is working.

I doubt that the reg would cause your problems, the battery voltage will not change that quickly,due to the reg.
More likely a loose connection or a short.

Harvey. :cool:

OAB is right on that one. I had the voltage regulator go bad on me. It just didn't charge properly anymore. Clearing the ECU would help only temporarily. The bad regulator also seemed to put the engine into limp mode. (radiator fans always on, difficult starting when cold, low idle...)

To me it sounds like the rest of the alternator...especially with the flashing warning lights. You can also check that the connector is also plugged very securely to the alternator. Perhaps some conductive paste would help if it is indeed loose.
