I put the ST to bed in the garage last October it was running perfectly. I plugged in the Opimate and left it untill last Saterday when I thought I would fire up the beast. The engine turns over but will not start. I took out a spark plug grounded it and turned over the engine no spark. Has any one got any idea's. I have been told that if the battery is slightly down on voltage it will not fire the ignition even though it turn the engine over ok. I am reluctant to go to the expence of a new battery if this is not the problem.
