[QUOTE=BuckyB;109722] I did check the battery cables and it appeared that the positive cable was a bit weak. QUOTE]
You put the answer in the question. Starting is it needing high amp from battery.
a weak positive battery connection can provide low amp but not for a high amp like starting.
Just clean both battery connection and bolt it firmly.
Personnaly to avoid battery connection fail i replace nut from bolt battery connection with nylon locknut.
finnaly if it can help you, there is a link to manual service
