Thanks for the info and snippet out of the service manual. I appreciate your time uploading them. I have a number of service manuals including the TLSB, but none of them have the detailed information I am after.
What I would like to do is create a base line for testing the actual pole coils and condensor, if it is possible, to allow me to use and confirm if either a condensor or a stator coil is either failed or on it's way out.
My understanding so far from another member who has worked on many LI's is that the coil readings will vary from between 0.3-0.4 ohms for lights and the ignition will be no more than 1.1 ohms. As also pointed out by him, what I did not take into consideration with my testing was that the metre reading was not zero when I crossed the meter wires over, prior to testing on the coil. It was 0.49, which needed to be deducted from my reading of 1.45. If I take my 1.45 reading, deducting 0.49 gives me a reading of 0.96 Ohms, which means it falls into the same category as an LI. However, this then makes my running LD readings I have taken from the green wire outside the magneto casing much lower as well.
NB: There is also a You Tube clip I have found of someone rebuilding a 2 Pole stator on an old bike (Not a Lambretta) and the reading coming out as between 1.4 and 1.2 ohms.
I guess moving forward, I need to review all my LD's and start to create my own base line for readings in this area. Then when I think one has failed in the future, confirm what the old readings were and if they have changed, rebuild the coil to prove the coil had failed.
If anyone reading this has what they believe to be a failed LD 2 pole stator ignition or lighting coil, that they are happy to part with, please let me know. Maybe put it on ebay with a starting bid of £1+ postage and advertising it as a possible failed coil and I will buy it, if you can let me know it's on there. I will then test, rebuild and confirm results, which may or may not aid others in the future with their diagnosing suspected faulty stator 2 pole coils
Thanks for reading.
