Question about 2005 Seat Alhambra 1.9
Second earth wire melted fuse box where does wire go?
Secondary ground wire fried!!? this tells me that your main ground did lose its contact somewhere.usually opposite the battery side. when this happens, and you try to say, start the car, all that amperage will follow any available ground it can find, usually through the actual wiring harness that covers the entire car. see, most vehicles have 2 ground cable setups..a main, and a secondary.. the main consists of the large cables as well as "ground straps" which look flat and are made of braided wire and run from the car body to the block and areas like that. now if these fail or loose connection, the only other source for grounding will be the loop i the harness which is not big enough to handle the amperage needed to run the starter motor when activated by the ignition key. now since yours burnt up, it must be replaced and all ground wires checked..also check for shorts in the system elsewhere, with a meter if necesary, you can also disconnect the battery entirely and connect a 6 amp battery charger directly to the cables(like charging the car without the battery) and if there is a short, the guage on the charger will peg over without fear of fire you will hear a buzzing sound where the short is (usually)..I have used this trick to find shorted blower heater motors or wiper motors on big trucks..if this ground wire is wrapped into the actual harness setup, you will need to replace it by cutting loose the old one, run a new wire into any part of the system thats not damaged, usually near the headlight fixtures, then run it back to the original starting point ,then its process of elimination as to what will work and what wont, remember, all circuits will function some with the charger attached instead of the battery, you will hear a buzzing or humming especially when checking the radio..good luck
