The large one is the VR, the middle one is the FI main power relay which should have a wire running directly to the battery. You should remove this wire from the battery. The smallest relay is for the rear window defroster. Yours probably doesn't work any more.

None of this sounds like a "draining my battery overnight" kind of problem. Just sounds like a problem with the batterys, the wiring, or the starter. A battery which works fine in another car should work fine here, unless it is discharged. The best way to charge a battery is slowly, using a low charge rate overnight. > I think that it is a leak somewhere in the electrical.

Clean the battery posts, the connections on the starter, and the battery clamps. If you have the replacement clamps that clamp on the cable they are probably no good and you would really be better off getting a ratty old set from a VW in the junkyard. Those will be better than new ones. If the external stuff checks out, other things to check are the starter brushes, the wire from the solenoid into the starter, and the starter bushings in the transmission case. - Jim Adney jadney@vwtype3.org Madison, WI 53711-3054 USA ------------------------------------------------ To unsubscribe, E-mail to: <type3-off@vwtype3.org> For more help, see http://vwtype3.org/list/
