Here's the deal.
It's 85 deg ambient. Oil temp 100c. Last of 10 AX runs. Wide guts in 2nd and.....backfire...black smoke, flames out the exhaust....cool. No spark. Sumthin in the ignition went poof. NO warning Whatcha think? MSD (it was hot to the touch) Pertronix (got a spare) Coil? Cap & rotor are OK. Magnetic Pertronix thingy on the dizzy is ok. I let the thing cool down for 3 hours, but no joy......permanent daid. |

Screwing around with electricals makes my haid hurt.
All that magic smoke running around in them wires is all very mysterious. Good thoughts about the 12v feed, M-A. I can't remember anything about how I wired it....except it is the red wire (IMG:style_emoticons/default/biggrin.gif) The Pertronix is THE likely culprit, tho I have heard that the MSD is heat sensetive.....and it was hot. 100C is the hottest oil temp I have seen on the car so we were in uncharted territory. Other than this small problem, the car is comming around. It was pushing on the tight stuff....bad enuff to make me hit a cone. I'll soften the sway bar a bit....unless someone has some 200 lb rear springs F/S. My co-driver Chuck was 14 overall at 52.7 & I was 23rd a half second back. The Chuckster had a good run going when the car puked. He rolled the last 150 yards with no power and still went 52.9. 106 drivers. SCCA is pretty competetive around here. That Z car whupped us'n for the class....damn, he's quick and he has a Porsche emblem with a slash thru it on the side of his car. To add insult to injury, he gave me a ride home.
