Clive,
I am aware of Darrens problem with his luminition module, but they don't have to be expensive. I bought a brand new one on ebay for £2 because the seller didn't know what it was!
I have a couple of J60 distributors, and plan to try to fit the luminition gear into my Ferret. I have all the training notes and modification instructions, and can pass them on if required. I also have a source for complete distributors at a good price, better email me about that though!
