had to go rescue my wife's 20TS today, which had just stopped dead while on the go. She couldn't remove the key and there were no dashlights working.
Thinking the barrel was stuffed I removed it pulled it apart and discovered the plastic housing for the terminals had melted a bit thus losing electrical contact. Hotwired it, started fine, ran for about five then stopped dead at a busy intersection (cnr Bell st and St Georges rd!!!) Connections were burning hot! looked like the the wire that lights up the dashlights was the culprit. Anyway got a push into the servo on the corner, and waited for the RACV. Eventually noticed the short was gone and I got it started and drove home 5 mins away. Thought it might be caused from the fan coming on so left it to get warm enough, but the wires didn't show any sign of getting even warm. What could it be - I don't want to fit a new switch till I'm sure the problem's gone for good.
