    Electrical issue!..Plz Help!

    Hi there peeps!

    I got in my car the other day (Mk 4 1.6 16V Petrol 98, unmodified) after it was stood for 24 hours and after just getting on the road, I noticed the indicators wernt working...nor was the speedometer.

    The EML was on, the hazards worked, break lights headlights, central locking and windows were all ok!

    I thought it may be a fuse, but they are all ok...so i thought about the ECU, so i unhooked the battery for 12 hours when i reached my desination...but no joy......the relay sounds cool..as the hazards ticked away nicely (unles theres a separate relay???)

    ALSO..it dropped its idle a couple of times and stalled....

    I really dont know what to do, I just had its cambelt replaced and a track end, and its due for its service and MOT..(I do the service myself, but dont fiddle with the electrics other than check theres no loose wires etc)

    Im at a loss to what to do other than take the bugger to VX.....any ideas on whats up?...im certain the speedos electric... On here I have only seen indicators OR speedo down...NOT both together...

    Any ideas guys?..

    cheers

    Martyn

    Unfortunatly my diagrams don't go back far enough for your car but on the slightly later ones a fuse controls the speed sensor, which is electric on your car as you say, indicators and reverse lights

    Other diagrams point towards the same fuse on your age of car so check fuse 29

    S*%T!!..now the fuse keeps blowing!

    I have taken all the lights off the circuits and also took the indicator stem off too...i unhooked the fuse for the hazards and the 10amp indicator fuse still blows....I even fired a 15amp (not 10) in and even that blew as well?

    I think I will have to contact an auto spark :-(

    my friend had the indicator problem on his ka fuse kept on blowing turned out to be one of the bulbs weren't in correctly so check all the bulbs and make sure they have been put in right

    Come to think of it I had that fuse blowing on a members car and the wiring was shorting out to the hazard switch and it could only be found by removing the center console

    Try unplugging the gearbox speed sensor and reverse light switch also

    Cheers guys...

    yeah i just spotted that post....

    Im wondering....recently i have been blasting the heater through the side blowers directly outta the windows, as I sit in traffic for ages in this summer heat and it takes the heat off the engine..( the temp goes down on the gauge)..i wonder if the constant heat across the dash has melted something?..hmm..Also when i replaced my battery a while back..i had to rip out the radio to find the keycode to reset ( I wrote the keycode on the top of the radio)..maybe i nocked something when i replaced it??

    Is the reverse sensor under the front passenger wheel arch like on the other motor you looked at?....i wanna find more about the gearbox as Id like to change its oil in the service as I havent replaced it before.....so will investigate...I know the Rev counter is attached to the gearbox..and thats fine..

    So i will remove all the lights, indicator stem plus those two other things and try again..BTW is removing the Hazard fuse sufficient as a disconnection, or should i actually remove the centre control panel..i noticed i lost the main display totally when i pulled the 15Amp fuse for the hazards.

    thanks for your time!

    Reverse light switch is likely to be on the front of the gearbox in your 1.6. You need to unplug the hazard switch to isolate the switch enough. Rev counter comes from the coil not gearbox

    I wouldn't expect the heat to melt wiring at all
