| Post subject: | Coil and hot starting |
Hi all I have trouble starting the old stick when it is hot. I have read that this is most likely the coil. Would it be prudent just to get one and see, or am I just throwing money away? Is there a preferred supplier for the same? Thanks. Justin |

For a test you can switch the two thin wires on the coil if it wont start when hot.. When you do that, touch the coil to feel if it's hot... If the car starts better after you change the wires you can buy a new coil  If you buy one, go for a Valeo one.. There is a lot of other brand coils wich are new, but as bad as an old one..

Thanks for that. I wondered if this would be any good: http://www.ecas2cvparts.co.uk/ignition- ... -1159.html Maybe a bit over the top. |

The coil in your link is great, I have one, wish I had three! |

I see no technical reason for a diferent way of sparking or heating dissipation by inter-changing the primary cables. But a lean mixture may cause an abnormal coil heating. The voltage required to create a plasma is much higher than when the mixture keeps a good stechiometric relationship. Regards. |

IIRC swapping the cable changes the polarity and negates any wear at the plugs, a duff coil will fail to work whichever way round its connected...wont it? poor hot start can also be tappets needing done coils dammaged by incorrect dwell, over charging voltage reg and leaving the ignition on without the car running. valeo, i was told that the machinery was sent to Argentina and so the SA coils have better windings, however the cases leave a lot to be desired.

Coils now'days are shit, hence the yellow coil from Ecas. We have been spoiled by good quality Ducellier and Femsa but those days are long gone. Today coils are substandard and do not last long. So always carry a spare in the boot. They are afterall very cheap. |

By reversing the polarity the electric field inside the plug gaps we can force the spark in case of weared plug. But I was just talking about the coil heating. And as Tom Duckpower wrote: ...If the car starts better after you change the wires you can buy a new coil ...I think the first thing would be replacing the spark plugs. I use to exchange my coil primary polarity every, say, 2000 or 3000 kms even I have the 123ignition installed among with the VISA coil (0,9 ohm primary) Best regards. |

Trust me on this just get a Yellow Harley Coil from roy ECAS we have them off road and they run Hot or cold and even under water!! that says it all we have fitted them for Years NO PROBS and they transform any car will fit ont to the pony asap!!! don't sod about with a valeo waist of time and old style technology and leak oil pony |
