When you switched on the wipers via the switch and they did not sweep through zone A and the swept area, at this point you said that the switch was faulty, how did you know that at the time of test? How did you prove it was not a blown fuse? How did you prove it was not a poor electrical connection? How did you know that the wiper motor itself was functioning OK? How did you know if the wiper motor switch was actually connected? Can you see where I am going with this? The testers manual is written in such a style that it identifes systems that are malfuntioning, but does not tell you that the malfunction is caused by a specific item, like you said in your case of the faulty switch? Even if the stork of the switch was loose in the pivot and you thought the switch was faulty, just because the wipers didn't operate doesn't mean that the switch is the cause? The reason for rejection you quote was probably written back in the day when we had vacuum operated wiper mechanisms ;D, where they would stop after moving if the vacuum was lost ;D, which does not help your case in the slightest . It would be interesting to see what other forum members think about it, but I think it is time VOSA updated the manual to give a RFR for wipers that don't work when switched on Dave

True Dave, but why does it give us the rfr on number plate lights "Bulb not working", After one irate customer failing a retest when he replaced the bulb whereas the wires were broken and needed repairing I now use "does not illuminate the number plate" They can do their own diagnosis

They had bulb not working for lamps with more than one bulb. That was before the introduction of multiple light sources. You would have known it was just a bulb 'cos one would still be working.

Or the bulbholder was duff, or the wire to the offending one was broken. But there isn't an rfr for lamp doesn't illuminate

May I drop a spanner in the works there lol , number plate lamps are wired in parallel , which means that if one lamp is inoperative, the other lamp will still function as normal Lamps which do not illuminate the number plate are normally working, but at a reduced illumination so that the light source is incapable of reflecting off the number plate Look at the Vauxhall Corsa B's, the number plate lamp is in the rear bumper, if somebody can prove to me that the lamp will illum inate the plate when working correctly, that will be the day, the distance is too far and in the wrong direction to reach it ;D Dave

So you fail ALL corsa Bs Dave. Yep wired in parallel, so there's a wire between them? But take for example your Corsa B. the number plate doesn't light up Is there an RfR for that? I'm not at a device so I can't check but I believe the RfR is number plate lamp BULB not working

Kjb,to answer your question "a wiper does not continue to operate automatically when switched on so opinions please,do you pass & advise or fail as I did?"
You are correct in failing it as the section 8.2 RfR 1.b states

inoperative or less than 50% of the light sources illuminating is the rfr now I think
