i am so gutted. my 1969 moggy was sat poorly for three yrs. we've just paid 1200 pounds getting it well again. i have been driving it for one day and the indicators have stopped working as well as the fuel gauge.
i have looked in my handbook and workshop manual but can't see what to do. unfortunately i am a typical woman and know nothing about cars.
i don't want to sell it i just want to enjoy it. please help in anyway you can
kind regards
melly

Check fuse box under bonnet on bulkhead. I think it is fuse 2 that feeds both these items. If fuse is not blown then make sure all contacts are clean and that the fuse is secure. It should be a 35amp fuse that is fitted.

Likely the wipers and brake lights have stopped working too. So best not to drive it any distance until you get it fixed.

It should be the fuse nearest the middle of the car that is causing problems. Look carefully at the fuse wire to see if it is broken. If it is OK then clean the contacts in the fuse box, switch on the ignition and the o/s indicators and wiggle the fuse around until the indicators start flashing. Now check the heater, brake lights and wipers.

Rather than wasting lots of money paying other people to do simple tasks, read up on Minor servicing, build up a decent tool kit to keep in the boot and get to know what is what under the bonnet.
That way if you do get any problems you can be on your way in a few minutes with the satisfaction that you have saved yourself a lot of money.
Such is the nature of Morris Minors, they do break down but it is often a small problem that is easily rectified.
And of course you can always ask on the forum.

thankyou for your help. the fuse now blows every time i drive the car after a couple of indications. when i start up the green light that used to be on the end of the indicator arm stays lit. the last owner made a new green light that sits just under the drivers glove box. for some reason.
i am going to have a look at the green wire that plugs into the bulb.
any ideas would be very welcome. just spent money we couldn't really afford on it so i feel totally disheartened and have a good mind to sell.

If the fuse is correct, ie 35 amps, then the reason for blowing is due to a short somewhere. If it only blows when you are indicating then the fault is in the indicator circuit. You can decide if its left or right indicator and search the wiring for that side of the indicator circuit. If it blows when either left or right is used then I would suspect the wiring to the bulb on the column or dash. The new light was probably made because column switches can be expensive so the new light would have been a cheaper option. Check the wiring to that new light isn't shorting to the bodywork. Don't sell just yet

yes you are right selling would be throwing the towel in with the little monkey! being a morris lover is a very strange thing. any other car and i'd get rid of it willingly! will check all the wiring and i'm sure the problem will be rectified. thanks again

Just come back to us if you can't find the problem but try to narrow it down by disconnecting certain parts of the circuit to help us out....

The other end of the green warning light wiring should be a pale green wire connected to the P terminal of the flasher unit.
Disconnect this wire replace the fuse and turn the ignition and indicators on. The warning light will not work but if the indicators work correctly then the problem is in the warning light wiring. You can rewire the warning light later by disconnecting the green / yellow wire from the oil filter (it never does anything anyway) and connecting it to the P terminal of the flasher unit. Now when you use the indicators the orange warning light on the left side of the speedo should flash.
If one of the indicators blows a fuse then you know which side the problem is, the only task then is to track down the fault to the front or rear of the faulty side. You can do this by removing the front indicator lens and taking the bulb out. The rear indicator should then flash rapidly but not blow a fuse. If it blows the fuse the the problem is the rear, if not it is the front. The fault is likely to be a bare wire shorting out against the bodywork which may take some tracking down or a faulty connection in one of the indicator light units but at least you know which area to look in.
The front / rear indicator wiring on the right is coloured green / white and on the left is green / red. The one snag to this diagnosis system is that you will need a lot of spare fuses.

thanks for the advice, if i give you a quick run down of what i have done thus far you may be able to help more....please.
the indicator stick has been bypassed in a diy fashion previously, i have checked the bulb in the indicator warning light, which was ok but replaced with new anyway. i have in addition renewed live and earth connections to the flasher indicator.
to the flasher unit there where two wires on the same terminal point 'p', i have entwined these and made a connection to the flasher unit.
all indicators work correctly and the fuse has not blown since i have taken all these steps, however and there always is a however..the flasher indicator still does not register even though the bulb is good as are all the connections to and from the flaqsher indicator light and the flasher unit. so that leads me to request your assitance with how to resolve this rather puzzling problem, before i buy a push bike, ha ha.

As the flashers are all working correctly you have solved most of the problem. Well done.
Follow my previous instructions and disconnect the wire from the P terminal on the flasher unit. Now disconnect the wire going onto the oil filter and connect it to the P terminal. This should give you a flashing amber light in your speedo.
When you have that working you can sort out the warning light at your leisure. It is usually better to rip out the DIY wiring and start again.

Check that you have a good earth connection to the column from the indicator switch. To test it, put the indicators on and run a length of wire from the side of the warning light to a clean earth point on the body. If the light flashers then you need to fix the earth. If not, take the bulb out of the holder and put your meter test probe on the connection that goes to the base of the bulb and the other meter lead to earth. You should be seeing 12v on the meter when the light should be flashing. If not then you have a break in the wire from the flasher unit to column switch.
