Believing the red reverse button is electronic as opposed to mechanical, I disconnected the battery cables. Then rocked the quad, moved the shift lever down a number of times, reconnected the cables with no results.
I tried holding in the shift/brake lever (the left one) and pushing the start button. Nothing.
When the key is turned on, the 'run' light is a bright red. The battery is obviously charged.
Do you have any suggestions???
