Re: MG TF battery light fault
Andrew Young
This is luckily only a basic charging system on these.You need to test the warning light circuit from the dash pod to the alternator.The charge w/light earth circuit to alt is via a thin brown/yellow wire that exits the pod.Just above the fuse box is a multipin connector block where you should find this wire.With ign on ,use a test probe to ground the light.If it lghts then the dash circuit is ok.Do the same at alt end,ground brown/yellow to test w/l circuit.If no light,then you have an open circuit somewhere to engine bay.The wiring diag shows this circuit goes thro the fuse box,but is only an in and out.hth
