    Boot light voltage

    I went to install some neons in my boot but it blew the invertor, So I bought some new ones and tested the output so it wouldnt happen again but on the multimeter it read 19v

    what would cause it to be so high?

    have you checked your multi meter is ok have you put it strait on your battery or on a friends car also was that with the engine running? if so could be a duff alt

    id think it was your meter cus dont think ECUs would like 19v and a cheaply made set of neons

    Should be 12v-14.4v

    id say your meter is out of calibration because id think at 19v all your lamps would have gone pop and most of the electronics would have done the same but if you find out it is actualy 19v i wouldnt try and use the car at all as you could get an expensive repair bill

    as above what does it read with the engine off

    also check you have a good conection on the wire that goes to the alt from the battery as ive got a feeling if the battery isnt conected to the alternator and the alt is spinning and producing power i think this can cause high voltage

    That was with the engine off, all power connections are solid
    Although the meter may be out

    Stick it straight across the battery. should read 12(ish) volts.
    Multimeters usually die completely, rather than wobbling a bit first..

    Its odd, cos i was looking for infor for a mate, who's astravan pops a fuse when you put a lamp in the load area light....
