Please welcome my new electrical gremlins-

[4x4_Welder]

Finally got the Hatch back on the road after it's brake and suspension upgrade, only to have a new problem: The brake fluid, parking brake, brake light, and battery warning lights all stay on most of the time. I replaced the voltage regulator because the lights would go out for a few seconds when you tapped the old one, now the new one buzzes when the lights are on at lower rpms. This wouldn't be such an issue, except that there is also no power to the choke and fuel pump when the lights are on. I've checked everything out, all the wiring seems to be intact, all the fuses are good, still there has to be something going on-

I wired the fuel pump off an accessory fuse so I can get to work and back, the battery is charging.

Anyobody have some insight on this, or should I continue with my original plan to rewire the car?

The diode trio in the alternator is failing (not the ones that charge the battery, but the ones that control the warning light circuit). Usually this is a pre-cursor to the alternator failing to charge. Best bet is to get a cheap alternator from PAP to confirm the fix and then have your alternator rebuilt by a reputable shop (Marine Electric in Ballard is excellent).
