I bought this sled that had caught on fire. It melted the harness so I decided to buy a used harness. I am 99% sure I bought the right harness but now I have no spark. What do I need to look for? The odd thing I did notice is that the old harness had a 2 pin harness from the safety switch. The new harness has 3 pin harness but so does the replacement handlebar. I can only think the replacement harness is no good, I have one that won't work, or I have something not hooked up correctly. This new harness does have a 6 pin plug that I can't figure out what it's for. The old harness was burnt so bad that I can't compare. Any held would be great!
