I recently put my DS650X back together and when I turn the key is have no light but the gages work when I turn key off the check engine and neutral light flicker once..... also clutch lever pulled back bike in neutral gear kill switch set on press the start and there's no spark.... now there's a wire that runs on the side of the oil filter how sensitive is that to heat cause my friend welded it in place with out me knowing and I'm wondering if that's the problem please help I'm out of ideas it only back fired once and no start

Thanks
