Default turn over problems

When ever my battery is connected it seems that my car want to turn over by itself without the key in the ingition.I took it to the dealership and they said it needs anew starter but I just put one on not even a month ago. What could it be.(Does anyone have the wiring connetion setup for the starter)

It sounds like a bad starter. When the new starter was installed a month ago was it working properly?

Here is the schematic for you.

Edit - I tried but I cannot get the picture to post.

It sounds like thestarteris permanently energised somehow or other.

Basically the starter motorcan only be energised by the solenoid contacts which close after the solenoid yoke has meshedthe bendix drive withthe flywheelring gear.At this point the starter is motionless.

After the bendix drive is firmly engagedin the ring gear, a set of contacts within the solenoid areclosedand these contacts thenconnect a supply direct from the battery toenergise the starter motor whichimmediately spins,cranking the engine.

There are only three components that can interupt thesupply to the starter solenoid and they arethe (1)ignition switch and (2) transmission starter inhibitor switch and (3) alarm relay, and Ithink it would be highly unlikelyany of theseitems would be the cause ofyour problem.

I'd suggest you disconnect thesolenoid supplywirefrom the solenoid (small wire - top terminal, the other rerminal will have a heavy battery wire connected to it) and, if the starter motor then still continues to rotate, I would suggestthe solenoid contacts arefaulty (welded contacts???) asthe starter motor is then being fed through the closed solenoid contacts which,with the solenoid itself de-energised, should be open.

If you feel this is beyond your ability, then I'm sure it wouldn't take a competent, proficient autoelectrician too long tolocate and rectify the problems with your starter motor.

Best of luck.

Yep, most probable is a bad starter. If you swap out starters and it still does it then, the only other thing I could think of is somehow there may be a short in the wiring that is constantly send voltage to the starter.

What does it mean if you go to start the car and the connector from the solenoid to the starter motor starts to smoke and or burns up

Usually the starter soleniod got stuck on. and kept it spinning.

As tech said, the starter solenoid is most likely stuck causing the starter to draw a LOT of battery juice. I would swap out the stater and see what happens

Thanks for the help but come to find out the power wire that were connected to the post were touching the solenoid outpost sending constant power to the starter.
