Morris Minor Owners Club

Hi all. Was having a look at my wiring today as the horn and wiper washer was not working.anyway without doing much tinkering I then noticed that I,ve lost power in one side of the fuse box the side which have the white wires at the bottom,no indicators the car turns over but will not start also the ignition light stays on with the ignition off.i can,t remember if I maybe put a wire in the wrong place.Everything was working grand before I started poking except the horn and window washers.I put an alternator on months ago.

The three white wires are only live when the ignition is on.
There should be three green wires on the other end of the fuse that the white wires are on.
The other fuse has a brown on one end and two purple on the other end

I think that maybe you put a wire in the wrong place, and maybe the fuse has either blown or the connections are corroded. The best bet is to look at the wiring diagram in the workshop manual and ensure that the pattern of wire you have at the fuse box is correct. With a multimeter, check for volts on all fusebox terminals, both with the ignition off and on.

For starting, it's the basics of checking that there is power to the coil, and that it is switched by the points. Is the petrol pump working correctly?

Thanks for reply guys.There is no power with the ignition on I,ve tested that already.what I have discovered is that the last owner has a black wire coming from the very end inner side of the control box which I believe to be going to the voltmeter and best of all that is joined in a scotch block with another brown wire running from that to the first side of the fuse box.This is possibly the brown wire you spoke of Andy with the two purple on the other end.wiring diagrams are like reading foreign language to me I,m afraid.

Simmitc forgot to mention no power to the coil or the fuel pump.

And it was all ok after you fitted an alternator?? What wire could you have put in the wrong place ?? Can you take it off again? Who fitted the 'voltmeter' and exactly how is it connected? Some pictures would help us.... The Ign and pump are NOT fused - they are fed from the Ign switch.....so you need to look first for a loose connection/wire pulled off at the Ign switch. Do the headlights work ? So the excellent colour coded wiring diagram at the head of this section. print it off and laminate it - to keep in the car .

Hi bmcecosse. Yes it was going grand after the alternator was put in only thing that never worked was the horn and screen washer they never worked from I got it.The headlights are working grand.i,ll take a few pictures tomorrow and post them.there are a few loose wire in the dash the last owner liked scotch blocks lol.i will copy the diagram thanks.

Oh dear - and you say the old dynamo regulator is still in place ? A picture of the connections there may help us.

Yes the regulator is still there.i will take a few snaps of the regulator box,connections,fuse box and connections and post them tomorrow.thanks.

Ok here's photos of the fuse box the live side which is the left hand side has two purple wires coming from the top and the bottom has one white wire coming from it and beside this we have a brown wire which I mentioned in my earlier posts is joined to the black voltmeter wire in a lovely black scotch block going into the voltage regulator as shown in the photo.No power from the ignition side but the ignition light stays on as as I connect the battery and won't go out.there's no power to the starter side of the solenoid.can u tell me what this red wire with the fuse carrier is for? The wiring looks a mess as I took the cover of do trace wires.[frame][/frame]

The white wire should be with the other white wires on the far lower right of the fusebox, only one brown wire going to the lower left as you have. The white wire in the wrong place is likely to be the live for the ignition live side of the fusebox, as opposed to the pump/coil feed.
You appear to have a regulator that is retrofitted from some other vehicle too.

Here is the back of the ignition switch.number 2 and no 3 have power going to them no 2 is the black spade head that has a green and brown but is connected to the white wires.no 3 is the brown /blue wire. no one is the white/red wire this has no power.when I go to start the engine its just clicking! I hope this is enough information for everyone to go on for now as my moggy is in a friends garage 8 miles away and I,m now heading home any ideas much appreciated even to say look at the state of that wiring [frame][/frame]

814xuw I put that white with the others and that has solved it bar there's still no power going to the starter side of the solenoid.

Looks like you are getting there. The inline fuse is for the side llghts, this should get power when the main light switch on the dash is on.
Does your solenoid have a button that you can push, if it does and you then push the button the starter should spin.
If the starter spins, try with ign on and that should start the engine

So there is no power going to the solenoid from the ignition swich the white and red wire.would I be correct in saying that this ignition switch is faulty?

Thanks Andy.your right that's what the fuse is for now I know lol.my solenoid has no botton tho.i removed the speedo cable to get the clock out yesterday and it fell on the ignition switch which made a few sparks I,m now wondering if this damaged the switch?

You say the solenoid is clicking, so power is going there .....sure the battery isn't just flat ? Charge it up.... The solenoid may not be properly earthed, and indeed may have failed if it is the 'square' type. But overall it's going to need a good going over and sorting out the wiring. Power should come to the Ign switch on that brown/blue wire - and the white feed out should become live only when you switch on, and the white /red only live when you turn the key further to start.

You could be spot on the battery could be flat as the indicators were getting slower then stopped. I,ll give it a charge tomorrow.The wiring does need tidying up its rough and as one of the other guys stated the regulator box isn't of a minor its a bit of a frankenmoggy but it'll tidy up.thanks.
