    I have a Bessacar E745.
    The reading lights above the side seats have gone off. (Due to me, long story)
    The hab wiring diagram shows a block of six fuses below the wardrobe. No probs, found those, but they dont seem to control these lights, all fuses intact.
    The diagram shows a seventh fuse, not part of a block, which I cant find.
    The diagram shows this as "EMC Lights".
    Anyone know where this fuse is, and what does EMC stand for?

    EMC is a lighting standard.

    The test requirements of these standards include conducted RF emissions, insertion loss measurements, magnetic field and electric field emissions, radiated immunity, conducted RF and transient type immunity tests on power and signal cables as well as ESD (Electrostatic Discharge).
    Examples of equipment that fall into the requirements of EN55015 & EN61547 are:

    • Energy Saving Bulbs
    • Lighting Ballasts
    • Lighting Converters
    • Fluorescent Tube Starting Devices
    • Dimmer switches
    • Light Fittings with active components (such as fluorescent fittings)
    sorry, cant help with the fuse location :Sad:

    have you checked the fuses with a multimeter....some cheap fuses may look OK but testing with a meter can prove otherwise.

    Thanks John
    (I think)

    It's the fuse itself I cant find.
    The diagram seems to have 4 lights on the absent fuse, which appears to be the culprit.
    Everything else is working fine, just these bloody reading lights.

    EMC = Electro-magnetic compatibility

    lights which don't emit an electro-magnetic field....

    i don't think we need worry unduly about that.

    thats what i mean....remove the fuses you can find and stick a multimeter across them...it could be one of them. :thumb:

    wiring diagrams don't always equate to the actual wiring method.

    "Mmm!!! its easier for me if i do it this way instead of how its shown in the book"

    I've moved them about, John, Keeping the right sizes of course, no change.
    None of the six block fuses seem to control the readers.

    Tried that, BIll.
    NOt daft enough, apparently.

    Pappajohn: I've pulled all the others in turn, everything on the block of six has a function. Got to be the missing link.

    FOUND IT!

    AS advised by Bill Tick59, | thought like a daft Geordie and looked where it shouldnt be.

    A single 5a blade fuse (the culprit) lives behind the control unit.
    This fuse only protects the reading lights.
    Need to gently ease cables upwards to expose it.
    Same for all Swift manufactured vans?

    John, do you mean the reading downlights under the overhead cupboards in the lounge area?

    in our kontiki they were all 20watt halogen bulbs....4 of 'em....and a further 2 over the dinette.

    4 x 20watt = 6.6amps.......why would they fit a 5amp fuse ?

    I'm wondering if its blown before and been replaced with too low rated fuse.

    unless yours are 10watt bulbs of course :thumb:

    Yeah, thats it.
    4 x 10 watt bulbs, John.
    All the other "house" lights are on two separate 10a fused circuits.
    All fuses are to strength as per the handbook.
    Sorted now. Nearly did me head in.
