Bought and fitted a brand new shiny imrc unit tonight.

car seems a bit better so its one thing def off the list.

now the problem is the battery light.

start the car and all is well for about a minute then something kicks in and the cars tone noticeably alters and the battery light comes on.

multimeter across the battery and it reads 13.8V before and after the battery light comes on.

took the car a run and it pulls fine until the battery light comes on then it wont rev and just dies away. sit for 2 mins and start it and all is well again until the battery light appears.

I have no idea what is causing this, any ideas?

it isn't the fans as they eventually come on one its at temp.

hopefully once this is solved it will be back to normal!
