My ws6 will not start, just baought new battery and alternator 17 days ago, and now i turn the key, loud click/pop with a spark from the ground wire leading from neg. bat. terminal, to passenger cylinder head. Thought it might be starter hot wire melted off trying to push current through motor to closest ground. Also 10 minutes before while its was running I noticed my oil pressure gauge sweeping from almost 0psi to say 30psi and the engine would bog up and down with the needle, yet the rpms remained normal. Acted just like a bad o2 sensor and then would act normal for 15 seconds, and then start it up again. Main thing is the no starting though. Thanks guys
