Battery. Tony C

I bought new plugs and they are on the way, could it be the battery even if the lights are getting power?

Have your battery load tested. It could have week cells. Tony C.

could be alot of things 1. battery should be charged to 12 + volts 2. test coils unplug them from the orange and red/white wires and spark plugs then test the ohms from orange to red white it should be between 2.25 and 2.75 / 3. pick up coil can be tested too i believe it should be 750 ohms between the black and each of the other 2 wires im unsure of there colors 4. bad TCI box 5. bad ground could also be the issue i went through my entire ignition system 2 weeks ago when i had no spark and after a week of trying parts on my other xs it turned out to be a bad groung between the battery and tci box that should give you some place to start good luck check all your grounds

Check for battery voltage at the red/white wire at the coils and TCI box. No power = no spark.
If no power check the fuse, check the kill switch contacts, the key switch contacts. Could be any of them.
