peugeot 1999 trekker 50?

just bought 1999 trekker 50 of ebay no spark seller claims it was stolen and ign wires were chopped he played around with it couldnt figure out where wires went but he since purchased a cdi unit which makes me think he had electric probs all along where do wires go and how do i test the coil .feels like an ebay stitch up. dec
