There should be no yellow wires. Perhaps the white wires have just "yellowed" with age.

I renewed mine with a sheet of aluminium but fitted it using spacers so there is an air gap between the shield and the floor. seems to work well as the floor never gets hot.

Quote "A series 3 Land Rover? No, the rot had set in by then, you need one earlier than that. When they started fitting plastic dashboards to the landy, that was when we lost the empire!" When they got rid of the galvanised mesh Radiator grille and moved the headlights to the wings, that's when the ...

These diagrams are very good, you should be able to identify it from the wiring colours going to your relay.
Mines a 72 so probably won't be the same.

Did the shoes touch the drums before everything was changed? If so you can put the old shoes back on and if they touch then you have the wrong size shoes, if they still don't touch, then you have the wrong size cylinders. Or worst case scenario, they are both the wrong size!

Interior light is a must, doesn't get hot and melt the plastic lens when you leave the door open. Front sidelights are also a good move but beware the ones with a blueish tint, MOT testers don't like them. I haven't had much luck with stop/tail, the tail is brighter but the stop is not so bright so ...

Carb wear is not sudden or intermittent. Go back to basics and check plugs and points. For the misfire check under the bonnet when it is dark to see if there are any stray sparks. A compression test will show if you have a blown head gasket , worn rings or burnt valves.

Forgetting about the electronic ignition for a moment and concentrating on the coil..... With the ignition on you should have 12v on one of the wires to the coil. Leave this one connected, disconnect the other, then use a temporary earthed lead and put it on the other terminal. When you REMOVE this ...

Does it have a dynamo or an alternator?

Well done, electrics aren't such a dark art after all!

Yes it comes out of the ignition switch on the white wire. Do you have voltage on the brown/blue on the ignition switch? If not do you have voltage on A1 on the control box?

Don't worry about it. Some of the grumpiest people on this forum can be the most helpful and knowledgeable.
Remember BMC Roy?

What major work? Was the flasher relay disconnected? It sounds like it may be connected incorrectly.

How old are your tyres? I had very old tyres (10 yrs +) on my MGB and when I got new tyres it transformed the ride.

How old are your cracked tyres?

Good result in the end. That's the beauty of the forum.

Is your car positive earth or negative earth? If positive then you would get a 12v reading when testing from the fuses to the positive terminal. Do you have a dynamo or an alternator? If you have a control box next to the fuses then check all terminations and take it off and have a look at the back....

I had trouble with speedo lights and wired an extra earth to the speedo and this cured the problems

Mine is a 62 and it had the old style relay that used to flash the sidelights so your system wiring, like mine, may be something that a previous owner has developed, having changed to newer style rear and front lights with amber indicators. Unless they used a later loom they may not have used the st...

Was the points video on how to set them or how to change them. A common problem with points if you haven't fitted them before is not getting the wire and insulator in the correct order. Fit one half of the insulator, then the points spring, then the two wires, then the second part of the insulator, ...
