Per earlier post, picked up from shop today. Drove to work, running great. Driving home, running great although I notice volts reading less than 12v, temp gauge not working.
Almost home, a few blocks away. Going down hill. Huh, did engine cut out. Why, yes it has. Turn key. It cranks but no start. As if no spark or no fuel. Coil feels quite hot if that matters. By side of road now. (IMG:style_emoticons/default/headbang.gif) |

as an aside, according to a marine site, specifically regarding petronix and coils. it states that petronix recommends the use of an oil filled coil with their ignition. that it doesn't exceed 4 amp out or the risk over overheating coil and premature coil failure. to measure output, disconnect both sides of coil and measure resistance, then reconnect coil with ignition on, measure voltage at positive terminal of coil. divide voltage by resistance, this will give amps, which should not exceed 4 amps. if it does,you risk overheating coil. i would guess it would apply to epoxy filled coils as well. it goes on to say that by thier nature, electronic ignitions have longer dwell, which also heats the coil. hope this helps, search malonemarine ignition.

I wonder if your car has good grounds. I know my car ran better once I put a ground to the engine,and replaced the chassis and trunk ground. Never got above 12 volts until I replaced my original alternator though. |
