My 1997 Yamaha Big Bear is being contrary. It sat for awhile as the battery got weak. However it would still manual start. Always put stabil in the gas. Got a new battery installed, fresh gas, checked plug it fires(on lawn mower). Will not fire on ATV. Starter is working. No juice to the plug. Put meter on spark plug wire, no reading. Traced wire to black cylinder shaped metal connection(under gas tank), no juice their. Trace wire back to black box with multiable connections. Color of wire was reddish orange, put meter in connector no juice. One of the other wires did have juice. That leads me to beleive that power from battery is going in to black box. Also the lights and on /off indicator lights work. What do I check next?
