Hello-- I replaced my coil a few months ago--it was no good. The new one worked until just tonight when the car died in the driveway. I am getting no spark, no reading from my timing light hooked to the coil-dizzy. My test numbers: 3.1 ohms + to - and 12.07 kohms from either to center post (this is lower than the 15-30 kohms that is the range of normal in my vw book). Key on, I get around 11.9v or so to positive terminal on the coil. Is the coil bad? Are there things that can cause the coil to fry? Confused. |

Yeah, I definitely didn't keep the ignition on. I seriously only had the hot-spark installed for 2 days and had been idling the car in the driveway for a total of 5-10 minutes before they burned up. I've heard that other people have had issues with these things. I'd put points back in but my braided ground-wire is shot. I suppose I can change the base-plate or solder a new wire in. Ugh. |

That, my freind, is what fried the unit - ask me how I know. I replaced my compufire twice before we found the problem. Car would run fantastic - then just stop. Fixed the grounding issue and have been fine ever since (1997). |
