Ok here we go, when you turn ignition off and remove key the batt, handbrake and heater leds remain on but dim? if you apply footbrake or wiper arm the ign light gets brighter and other two go out? Also when you turn ign on the oil light comes on as normal but no batt light. Disconnected fuses, relays and ecu one by one but lights stay on dull? Earth issue maybe. Any advice gratefully received.
With the Yellow disconnected and the ignition keys removed (Warning Light/Lights Glowing), check with a multimeter if there is a voltage between earth and the Yellow cable

Are you sure that you have removed all the relays and also that an incorrect relay hasn't been fitted somewhere, water or corrosion in a relay will cause this fault., also water or corrosion in a plug or in the fusebox

Sorry, you've lost me
I suggested you disconnect the warning light wire from the alternator to prove it was or wasn't the alternator
You having disconnected the alternator proved that the alternator isn't at fault
Nobody here will suggest it's the alternator as you've already proven it's not

I had a similar issue on a totally different car (big old Sequoia). All sorts of things would stay on after removing the key, but seemed to be running at very low power. The starter position of the key switch was weird too, starting without turning all the way. I thought it was the trailer wiring, then assumed the alternator.. I had the battery checked, found a dead cell and got a new battery and it’s been perfect ever since.
Yellow battery wire?????????????????
I thought there was a Yellow warning light wire
Due to the fault vanishing after disturbing the wiring at the alternator I suggest you ASAP disconnect the battery and check the wiring loom in the area of the alternator and further along. What you have described suggests there could be cables rubbed through and shorting together
Is the thin warning light wire at the alternator yellow?

Yes just to confirm the yellow wire I mentioned is the small battery tell tale wire.
OK. With the fault on the car (Keys Out) the thin yellow warning light wire should be showing a voltage that is lower than battery voltage and that same voltage that shouldn't be there is travelling along to the battery warning bulb in the cluster, it then travels through the bulb and down to earth through one or more circuits such as ignition relays or lighting circuits. When you put your foot on the brake that voltage that shouldn't be there travels through the battery bulb, through the brake light switch and down to earth through the 2 x 21 watt brake light bulbs and this is why the bulb illuninates at full brightness when applying the brakeTake a look for rubbing cables, they often firstly rub through at a bracket or other object and then rub/short together, this scenario often takes place close up to the alternator body or where the cables run from the alternator around the engine etc
