indicators playing up

[MriavGraves]

my olive has decided that she cant be bothered to flash her indicators. When i indicate left or right the buzzer that only used to work now and then is a constant buzz with a constant light on the stalk, front two indicators on car are on with out flashing and both back ones are off. This fault started with no warning wilst out driving one minute they were working the next they werent, if it wasnt for rear ones being off i would have thought flasher unit any one had any thing similer

I would check the flasher unit first with a known good one either this or a bulb has blown if it's none of these then check for broken and or dirty corroded connections.

Strange that BOTH rear lamps have failed, together. I would check the bulbs anyway - and perhaps a common earth point has failed?

iv had a cup of tea had a think had an other cup cos that wasnt working and i think your right bmc might earth in back i did going boot before fault cos i noticed a starting handle hole on front bumper (this is my first moggy but is a 69 2 door 1098 supposed to have a hole in front bumper for handle i know that might sound sill to those who have them)and wanted to see if there was one in boot and i got back triangle bag out of boot but it was just funny looking jack. i may have disturbed and earth. And a positive earth at that. Is there any thing i should know about positive earth before i start i pursume digimultimeter be ok, before i turn ignition on put indicator on and connect a wire from body to rear indicator positive earth to see if the indicator comes on and do rear indicators have separate earths

[bmcecosse]

Either that - or you have pulled the wire connections apart. When you have a failure - always look to what was done immediately before the failure...backtrack and reverse any changes made...

tried a make shift earth that didnt cure it lets try the flasher unit can some one tell me where flasher unit is pls is it hiding in the steering column

[LouiseM]

Your Minor is a 1969 isn't it? If so, the flasher unit should be under the bonnet. It's a small silver cylinder usually fixed to the bulkhead:[frame][/frame]

[bmcecosse]

It's NOT the flasher unit when both rear bulbs are not lighting up. Are all the other rear lamps ok??

[lambrettalad]

what a lovely engine bay,puts mine to shame

[MriavGraves]

i now think its a earthing fault, break lights go off when indicators are on, i must have not bin connecting the earth properly i have the work shop manual can someone tell me which wiring diagram is for a 69 moggy cos i cant see the flasher unit on any of the diagrams

[MriavGraves]

fixed it yipee it was bad connection on buzzer box beside flasher unit. Any one know which wiring diagram it is in work shop manual for 69 moggy

[LouiseM]

There's a wiring diagram 'sticky' here: http://www.mmoc.org.uk/viewtopic.php?f=11&t=28295

'buzzer box beside flasher unit' ??? You got me there! Barry's 'simplified' wiring diagram is excellent - well worth printing a copy off and laminate it - and carry it in the car.

I take it by your post bmc that the small box beside flasher unit is not original for a 69 moggy, come to think of it it dose look as thow its quite new, so dose a 69 moggy suppose to have a on off buzz when indicators are on, or is it just the little green bulb on end of stalk the only indication that the indicators are on

[MriavGraves]

going to stanhope rally Sunday, dont want to be put in class 3 Category rather than class i me thinks i better take it of

[bmcecosse]

That little box is certainly not standard - if it is just a 'buzzer' -then I can't see how it could affect the rear flasher bulbs, and not the fronts But as long as it's fixed - be happy!

[MriavGraves]

After the excellent engine bay example by LouiseM, when i touch the little box beside flasher unit it stopped screaming ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh and went to normal tick tock heard front indicators go on and off played with wires went on constant again with ahhhhhhhhhhhhhhhhhhhhh from little box so i made sure wire was secure and wont come loose by jiggling about with driving, and it tick tock fine indicators flashed stalk bulb flashed green every things fine then go to brothers house and every time you apply breaks ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh whilst indicating, so got douglas sit it seat, foot break on and indicator on. front indicators on and you guessed it ah, at the rear the side the indication was for with foot break pressed stop light was on off on off only the foot break makes this happens with lights on wiper on heater on interior light on indicators work as they should for each side i will just drive with out using breaks untill monday lol then take box out of circuit and see if that cures it

[MarkyB]

Look at the earth point at the back, not the flasher unit.

[bmcecosse]

As I suggested way back - it's an EARTH problem at the rear lights! Just remove the silly little screaming box and throw it away.......
