OK Ive done a search but didn't answer my question,
this morning i took my car to panel beaters, had to disconnect battery for welding, then when i was leaving it wouldn't start, just ticks when the key is turned. so put jump start pack on it and it started straight away.
drove home thinking i just had a flat battery and the drive home would charge the battery (which is relatively new) back up to normal, but no! it did the same thing. jump started it and it was sweet.
so i checked the connections/terminals, they seem all good, tight as and not corroded.
is my alternator naffed? its weird though because Ive had no issues starting or charging recently.
