Battery light on

You'll have to take the bumper off again, and locate the sensor that is on a bracket lower slam panel, not the bumper one.

Look up and the two wires from the sensor run into the loom (in-between the radiator and the slam panel ) that supplies the fog lamps and indicators.These are subject to a lot of road moisture and corrode very easily.If memory serves one is yellow brown the other green. Also check the terminals on the sensor itself for corrosion, as they and chafed wiring can be subject to intermittent contact whilst on the move.

Thanks snagger, if we're talking about the same sensor, then I checked that yesterday and re-insulated the cables. Round sensor about 2p size with the same connector type as the alternator? Looks like it runs back along to the horn area, which I couldn't check due to fading light.

Looks like I may have to go through them all again 😩

Very annoying I know Graham but as you know myself and Ron have both been down this road
I'm out of ideas now but it does seem to be the case your obd shows an adequate charging rate even though yr dashboard charging light says the contrary so I guess it could be said progress has been made
Keep us posted buddy

Yes that's the one, they both run back up to the grey multiplug in front of the washer bottle., check either side of this plug for frays as well. (Pull the sensor plug on and off a few times to clean the connection of any corrosion) .

It then disappears into the inner wing via a grommet behind the washer bottle (another chafe point.It comes out of the rear of the inner wing roughly in line with the bottom edge of the windscreen, and joins the loom running under the dash high up in the bulkhead where the firelining stops, then splices onto the ignition switch connection, and then into the main loom above the plenum chamber, and onto the ECU.

Where the loom crosses over the wing behind the headlight is a favorite spot for chafing as well.If you find any here, after repairing cut a small piece of hosepipe in half and bind to the loom where it meets the wing, to protect from further damage.

Hope you find your fault, took me a long time.

Just a thought, but is it not possible to do some resistance measurements on the relevant wiring, maybe find which wire, going where, is faulting, or even eliminate wiring fault ?
