Title: No spark Post by Tailgunner on 07/11/13 at 07:28:39 Hi. I've been riding Savage since last autumn without any problems, but that time is over and my bike doesn't work anymore. On the first day it started to sporadically loose ignition under load (when accelerating) but i returned from trip without problems. The second day i sat on bike and tried to start it but it produced only few sparks and it was all over. Now there's no spark at all. I checked as it is described in clymer : - signal generator (resistance is normal) - coil (both resitances are ok) - spark plug I also checked wiring, fuses, switches. It all seems fine, the starter cranks the engine well. Seems to me like ignitor is the problem, i looked inside to see if it's burned or something but it looks fine. Could the coil or signal generator be faulty despite the fact that their resistances are ok ? |

Bypass the clutch and sidestand cut-outs... (jumper the two wires together) at the clutch lever on the bar, and the green connector under the seat for the sidestand... |

Title: Re: No spark Post by Gyrobob on 07/11/13 at 08:49:27 Let's assume you have a good battery, or that you have the Savage hooked up to a good battery (in a car maybe) with jumper cables. If you pull out the sparkplug, plug it in to the sparkplug lead, ground the plug to the head, and hit the starter button, do you see any spark? |

Title: Re: No spark Post by apache snow on 07/11/13 at 09:28:10 Automotive charging systems put out a great deal more amps than a bike. Although connected for a short time will not harm the battery, the higher charging capacity of the auto could damage some of the bikes electrical systems. Although I have never experienced this personally, I have been told that it can happen. ;) |

i've already did that a while ago, when I had problem with starter not working. But this time starter works.. I tried connecting extra 12v battery, checked spark plug outside engine, i used few other plugs but none has given spark. Spark plug wire seems to fit tight but i'll check it again. Main clue for me is the fact that the day before it started to loose ignition at full throttle, like the spark wasn't strong enough. I assume that if the signal generator was faulty it would be independent from engine load, only the engine speed would affect that. |

Engine load and throttle settings can affect the spark process. An engine requires more spark energy at heavy throttle settings for some reason.....maybe the resistance across the air gap increases....but for whatever reason if the spark is weak it will often show up only at higher throttle settings. |
