2004 1.4 fiesta battery light staying on

[mk5transitjay]

Hi, my sisters has just brought the car and the batt light is permently on. we took it to a local garage to be plugged in on diagnostic and the only error it come up with was charging relay error..... he turned the code of twice but after 20 seconds off it being of the light came on again both times. now i have been told these cars are common fault with part of the charging loom wires breaking and can cause this fault.. anyone on here able to help her out a bit more in locating this common fault and a easy was of fixing it.. the garage also tested the battery charge and said its charging fine not 100% but enough, and he dont think the alternater is causing the light to stay on... any help would be appreciated and if fault is fixed i dont mind transfuring over a drink to the person that helps me as a little thank you. many thanks in advance

broken wire

ids will tell you this and point you in the right direction these garages only have snap-on readers and are not manufacture specific

waste of money realy these can cost upto £6000 for the top of the range stuff from them

also live date will tell you if its charging or not

thank you karl thats a good starting point and i will get under the bonnet in the morning and have a look for her, we have a good local ford breakers up the road from us that should have the loom in stock if it is the wire corroded. there is a slight split in the 3 way wire block that comes out the alternator would that be the cause it is connected still but the pvc coating is torn a feww mm and the copper wire is showing through....again mate thanks for your reply really appreciate the time and if this is the fault a will sort u out a drink

iam only going of what you say on here mate but that is the loom for these and it corrodes at the other end off alternator end

also try putting a live to the alternator signal wire

but is not advised if you dont know what you doing you will blow the ecu as these are smart charging system
