Those don't look too bad to me. You have to bump up the range for the secondary winding (HT lead) as it's much higher resistance.

I did to get the high reading.
So..... if I can get a spark at switching on off then the amplifier is OK ? But cant get a spark when pushing the start button ? Kill switch has been bypassed

Although this does apply in some cases there are, like my V50, some instances where the coils are 12v connected in parallel and Ian's link also mentions 12v coils. Assumption has to be that if the spark disappears when cranking over then starter may be taking too much of the batteries available power, which usually means a poor connection somewhere. (now there's something new for a Guzzi!!!!) CHRIS |

the coils are 6v. Back to tracing all the connections then

As usual struggling to diagnose from a distance and not able to actually look at it.
 But... OK so if sparking when turned on an off, but NOT when engine turning, then suggests it's not getting a signal from the timing pick-up sensor. The 2-pin rubber encased connector for this is another iffy area prone to oxidation and bad connections. Or broken wires. You need to do an Ohms test on the pick-up coil via this connector to make sure it's OK. The 2-way plug pins may was cleaning (aka, scraping shiny). Re the wiring and missing 5-pin plug, sounds like it's already been modified then to dispense with this plug. HTH |

Have you read this Jim? Scroll down and there are various tests listed.
http://www.eurospares.com/geninfo.htm The pickup coil is probably around 200 ohms, but yes, I would check the connections between the box and that pickup. As the above information sheet says, if you can get at the pickup, make sure the rotor is well away from the coil and you should then be able to test for a spark by moving a screwdriver past the coil. They talk of bench testing. |
