If your OVP has a single 10amp fuse then you probably have the notoriously faulty Siemens/Austria OVP p/n 201 540 38 45. The fuse can still be intact, but OVP bad. The new ones have 2 10amp fuses on top. This is where I'd start.

You might also want to check the voltage regulator attached to the underside of your alternator by 2 phillips screws. Pull it out and check the spring loaded brushes. If they're short and worn, then replace it. $10 for a generic here on Fastlane.

Good luck!
