my engine layout appears to be similar ,i have examined the cable from the alternator again the one that leads to the battery junction box and it appears to be ok theres no burn marks or any damage apart from where it connects to the alternator . theres a great big lump of solder on the end of the cable about 1 inches long ,i cannot see the crimp because its encased in solder . the opposite end at the fuse box looks fine .im not quite sure i understand your procedure for testing to determine whether it is this lead or not , could you perhaps enlighten me a bit more? i have booked the mechanic back on wednesday morning to do the job for me .apparantly the wire is called 'the alternator auxiliary cable' by ford who charge
