1998 Ford Escort Help with Electrical Fault

I had a problem with the Altenator and the original battery as I have had the car from new and not replaced it. Basically the car Ignition warning light was appearing and not going out. I took the vehicle to a local Ford dealer and they probed the battery with the Engine running, it was outputting 10V so he said as I thought that the Altenator had gone. I replaced this with recon'd unit that was known to be working. Changed the Main Battery as this was gassing on bench charging and never getting to full charge after 3 days of charging.

Fitted new battery but light is still lit. Checked battery voltage with lights and Hazards running plus radio. Output was 13.8 - 14.4V which appears normal to me and the manuals. Checked the output at the Altenator and this was comparable with above. I have not checked the Current yet but is this likely to affect the above as a new battery shouldn't be drawing a full 80 Amps Should it?

Anything I have missed or need to also check would be appreciated.
Thanks,
Austin
