Hope you can help please.
Had a really great day out but whilst practising slow speed manoeuvres one of the engines just stopped whilst in neutral. It will stubbornly refuse to start there was no adverse noise or misfiring beforehand but I did notice the charge voltage suddenly stopped charging a little while before. I thought this was in initially a loose V Belt but this was not the case and battery is fully charged.
I am going through the Seloc manual for testing the Renix Ignition and so far all looks good but I cannot remove the coil yet because of rust and so I have sprayed penetrating oil on the screws and will have to wait next weekend to continue further.
But … hoping for some clues. I have a set of spark testers and I am getting a good spark at the coil but it looks like only no.1 cylinder has spark.
My guess is distributor cap and or rotor arm, but would welcome any views. |

I would run a compression test first to make sure the timing belt has not slipped. If the compression is too low in all cylinders, the timing belt may be the problem. Keep in mind that yours is an "interference" engine and if the timing belt is wrongly installed damage to valves and pistons may occur. |

Hi – thank you for responding.
You are right of course... I may be able to borrow a tester, I was kind of hoping that may not be the problem, I guess it was the loss of charging voltage a while before the engine stopping that led me to believe it was an ignition problem. |

Ignition is one thing, charging is a completely different one. If you are getting spark (even if at one spark plug) then there is voltage reaching the coil. Charging is alternator related.
The problem could be due to a number of things, but you have to start troubleshooting somewhere. |

If your timing belt has slipped you will still get spark at all plug wires. You will only get spark at a single cylinder if the rotor is under that cylinder and not turning. A broken timing belt could cause this. Best to remove the cap and watch the rotor while someone cranks the engine. Unplug the power wires to the coil first to avoid stray spark. |

Update:-
Ben was correct – The timing wheels and the rotor arm are not turning.
The belt has not fully broken and is in situ, but on closer inspection I noticed a couple of timing belt teeth in the bilges.
Looks like a major problem now so I will arrange for a lift out at try to get it repaired for next season. |
