After some years running with no problems something happened this summer. I had finally got the a/c working very well (after fitting new condensers). Returning home, engine refused to stop on the ignition switch. But what was incredibly worrying was the fact that the ignition switch had become too hot to touch!! So that was quickly replaced. Taking a close look at the wiring diag suggests that the live feed to the igntion switch comes direct from the battery (actually via the starter solenoid), without any protective fuse or relay. This is potentially incredibly dangerous - anyone else discovered this situation?
I suspect the a/c contributed to this situation. Some terminals on the INDAK switch were impressively 'cooked'. But the a/c does not figure on the wiring diagram (the hand-drawn item that we probably all have by now). I obtained that wiring diag from a CD passed on by Bud Jones, who actually added a terse comment to his copy which reads 'See notes on previous page about installing <can't decipher text> fuse block to power relays. This lowers ignition switch operating temp.' So it seems Bud encountered this problem (or should this be 'design oversight'?!), but I cannot work out his solution.
I would be most interested to hear if others have encountered this problem, and how they addressed it. Meanwhile, I'm flat on my back under the dash mapping out that jungle of spaghetti!
