When car is trying to start but will not turn all the way over what is this?

Answer 1

There can be several causes of this, the most common one is a flat battery. You can test for this by recharging the battery, or getting a "jump start" from another vehicle. If the vehicle starts OK on a fully charged battery, or with a jumpstart from another vehicle then you have either: The battery being discharged by some electrical device being switched on whilst the vehicle is parked, or the battery is not charging up properly during normal use of the vehicle. Another cause is a bad connection between your battery and the vehicle body. The bad connection can actually be the battery terminals, or at the junction of the battery cable and the vehicle body, or it could be the link strap between the body and the engine. The solution is to remove the connections from the battery, and undo the connections where the heavy battery cables meet the body and the engine, and clean them, removing any rust deposits and corrosion that may have formed on the mating surfaces. It is also possible that the copper in the battery leads has become "tired". Over time the copper leads can loose some of their efficiency in conducting electricity which can affect the starting ability of your vehicle, particularly in cold weather. The only remedy is replacement of the battery leads. The other possibility, and usually the most expensive one! Is that the actual starter motor may be worn out. The electricity is fed into the starters armature by a pair of brushes which are made from carbon. These can wear down and become effective, the surface and that they contact, the commutator can become damaged and ineffective.
