Unfazed: sorry to disagree with you, but the voltage measurement is very useful. You can't have a 12v output from the relay with the motor not turning and blame the relay!
Intermittent faults are a nightmare. All you can do to pinpoint it is to ignore the results you get when it's working OK and concentrate on those you get when in faulty mode.Perhaps the next step is to try a voltage reading on the starter motor itself to eliminate the cable and connectors from the relay as being the cause.
Would it not be best test these things when its cold, ie before you've tried starting it on the button at all?There's more chance then, that the results you get are 'true'.If you've tried once or twice on the button before testing, the chances are that the third time, the testing time, has sorted the issue again and the readings are false?Has been mentioned before but nobody actively mentioned trying it from cold before trying it on the button if that makes any sense...
yes , point taken - twice , cheers for the humiliation

The smart ass arrogant mechanic said to my neighbour when he explained what I had told him said and I quote "What the foc would a fellow who fixes phones know about car electrics" He was insisting that the starter motor was faulty and it would cost 100 pounds, I got a solonoid from the breakers for a tenner and put it in for him.I opened the solonoid showed him what the problem was and he took it back to mechanic who told him to foc off, he did and changed to a different mechanic which he has been using since
