No spark Rubicon

I have a 2003 Rubicon that suddenly has no spark. It ran fine when I parked it for the winter. I looked for spark with a new plug while holding it to a ground a spark plug is getting nothing. Any suggestions as to what would cause it to loose spark from sitting a couple months.

Can be anything. Rodent damage to the wiring is a common one. Best to get a workshop manual and do the ignition circuit tests outlined. The Rubicon is electronically one of the most complex non fuel injected bikes ever, so tracing wiring faults can be difficult on them.
