2005 rover 75 had a dead battery yesterday. Found out the wipers had been going on and off throughout the night. Jump started the car and took the fuse out for the wipers in the afternoon but this morning car battery was dead again. Any suggestions what’s going on or how to save the battery?
If you know how to use a multimeter and understand ohm’s law, then do a voltage drop test across the fuses until you find the circuit(s) with parasitic drain. Use a chart like this one. Then fix what’s wrong with those circuits.
If you don’t, then find the best automotive electrician in your area.
