My 2000 vr6 Jetta has weird electrical issue. When I accelerate above 20 or 30kmh the electrical ii n the car goes out completely. The gauges go dark and the needles drop the climatronic goes dark, no seat power nothing. Thr car still has full power and there's no change in the way it drives. When the RpMs drop then everything pops back on... Someone suggested alternator but it puts out 14.5 volts on multimeter and the car still runs when the negative is disconnected from the battery I cleaned the grounds under the battery but the problem persists. Any help would be greatly appreciated. Thanks!

Check a conection cable between chassis and engine.Open and clean terminals.Put them back and check voltage.

SOURCE: When car warms up charge drops to 12 Volts

check for loose or worn out fan belt

Check all of your grounds. The ground to the engine and most likely off of the negative battery cable one should screw into the fender or close to it. Clean them off with a wire brush. If need be replace the negative battery cable. If the problem persists check the charging wire that goes to the alternator and replace that if need be.
Thank you,

SOURCE: I think I have an alternator problem? The charge

Hello
The normal charge of alternator on idling is about 13 to 14 volts. 12 is acceptable but keep in mind it will need attention soon. The needle fluctuates due to the revs of the alternator - there is nothing to worry about. Just look that the charge is always above 12V on idle.
