I find the independent autodiagnos technical helpline a very useful service The 2 guys Dave and Ken always make a big effort to give quality advice. Especially for someone like myself who is a sole trader and works alone this service can give some valuable lateral thinking whilst doing diagnostic work. For anyone who hasnt heard of this service the fee is only just over £2 per week which is money well spent. Do any other fellow UKAT members use this service? I understand that they are undersubscribed and need our support to keep going. Details can be obtained from autodiagnos tel no 01612 094 470 regards john sartain
