Just shows how you can get fixated on a fault only to find its something else.
Started off with my ZS Derv not starting.
Checked the positive lead from the battery to the starter motor and sure enough I could move it, not tightened up enough, so undid it and it crumbled away in my hand.
So a new heavy duty crimped connector required, couldnt find one, so used an old earth lead and pinched the one off that. All connected up and turned the key and nothing.
Then I remembered that the push on connector on top of the starter motor can give trouble. So pulled the connector off, emery cloth to clean it up, reconnect it and it fired up OK. Sorted.
Then it wouldn't start, sluggish on turnover, charged the battery up as its not used daily, fully charged says the charger, starts but still sluggish.
Tightened the positive lead, and it started easier, but soon got sluggish, to not starting.
Goggled it and found that the plunger in the starter motor can get tired. My ones done 104,000 so I suppose the newness has worn off.
Bought a new starter motor and now the engine whizzes over, like it has never done since I bought it 8 years ago.
So that slow turning over motor, might not be because of the battery, leads etc
