Fuse Confusion

Discussion in 'How To' started by snotty, Jul 29, 2017.

  1. A handy way to identify fuses to tap into for, say, radio installation is to...look at the cover of the fuse box. I'd bet most folk don't realise that VW helpfully grouped and marked the transparent cover with the fuse functions, in Bosch/DIN-terminal-speak.

    1, 2: 58. Side, tail lights
    3, 4: 56b. Low beam
    5, 6: 56a. High beam
    7: "K" (accessory position, may not actually be linked across to 8, 9 at base of fusebox)
    8, 9: 30. Unswitched +12V
    10, 11, 12: 15. Ignition switched +12V

    Tap into the appropriate fuse at the top terminal.

    Bosch terminals here, a lot of them still used on modern vehicles:

    I've seen a lot of busses but none have ever had the cover on, rare bit of kit!
    Nice info though cheers.
     
  3. Does usually go missing, I think.
     
  4. I bought a brand new fuse cover from JK, I think.
     
  5. That's where mine came from.

  10. Trivial update: "X" supply not maintained when cranking the starter. 15 stays at +12V when cranking.
