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. |

I got the car home this morning (it spent the night in the PIR in-field, top off....whut, me worry?). Got away with one there (IMG:style_emoticons/default/boldblue.gif)
Some quick trouble shooting: 12v to the MSD. An MSD troubleshooting method shows either the coil or the MSD is bad (it by-passes the Pertronix)...the coil is MSD, also. I gotta call MSD tomorrow and talk at em...make sure I'm doing it right. Also find out from them how to check the coil (it's usually resistance across the terminals).....I gots a spare POS for everything in the world...except an effin' coil. Also discovered a trunk full of oil.....that sux. Overflowed the catch can. Sumthin' else to worry about. (IMG:style_emoticons/default/sad.gif) Compression check showed 150/160 cold.....humm. Usta have 175 warm.....I'm agin' it. (IMG:style_emoticons/default/mad.gif) |
