If you have 14.5 volts at the battery and 14.3 at the alternator, either the tester is faulty, or you have a defective 24 volt battery:rolleyes:
Engine off, battery should have 12.5 volts to 12.8 volts, engine running at 2K rpm you should see 14.2 volts at the battery, a little more is OK.
ABS light can be battery voltage, sensors or ECU. Diagnostics may be needed.

Sounds like the alternator is fecked, you should see 14.2 volts at 2K rpm.

Unless there are corroded connections, it will either be the ABS ECU or the modulator. If your lucky it will be the ECU, they are not expensive on Ebay, they are a known failure item. Make sure you get exactly the right one for your car if you decide to go for one.
