Sometimes the starter don`turn

Where did you connect the positive power wire? It sounds like you connected it to the wire that activates the starter motor when you crank the engine. In this configuration, the stereo will only operate while the car is cranking. If this is the case, when you release the key from the start position, you turn off the starter motor AND the stereo. You'll have to find another power wire to connect it to either to let the radio play all the time or to an accessory wire to allow it to play only when the car is running or in the accessory position. Good luck.

Hi,

Check the starting solenoid (most likely) and/or the starter (likely).

The starter system is initiated at the ignition switch when the key is turned to start. At this point, the ignition switch then provides +12VDC to the staring solenoid. The starting solenoid then performs two (2) functions. It provides the switching action (hundreds amps) from the battery heavy cable to the actual starter motor. The solenoid likewise pushes a small pinion gear along the shaft of the starter motor to engage the ring gear. The ring gear is of course on the edge of the flywheel which in turn is attached to the crankshaft.

Starter system problems could be corrected by:
1. check battery, battery cables and connections;
2. charge the battery if required;
3. clean brushes and guides of brush holders of the starter motor;
4. clean the commutator and commutator segments;
5. check/replace the armature or field coils if determined to be defective;
6. in some extreme cases it could be the drive pinion or the flywheel gear ring is defective.
7. often it is the big switch that the solenoid activates that looses contacts causing no +12V internally to the motor.
8. It could possibly be a defective the IGN switch itself. Relative to this, you might try and check the connectors/terminals and electrical joints.

In the picture below, the upper portion is the starter solenoid while the one below it is the actual starter.

Given the amount of work to overhaul a starter, you might consider just replacing it. On the other hand, a solenoid is repairable except when burned.

This of course assuming that all other vital components of the car are working.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

if the engine turns over when cranking its working. you don`t say what the actual problem is. at the starter on the large terminal you should have battery voltage all the time. on the small terminal you should have battery voltage only when trying to start the car. if you do have power here then while trying to start the car tap the starter if it attempts to turn over the starter is no good. if you don`t have power at the small terminal then you will have to check for power at the solenoid/relay on the inner fender on the drivers side on the S wire when trying to start the car. this wire feeds battery voltage to the starter on the small terminal, if you don`t the solenoid/relay is bad. if you do then you will have to check for a damaged wire from the solenoid/relay to the starter. sometimes the starter motor could have a bad ground connection were it bolts up to the engine.

Then you found the problem bad connection also replace the terminal ends

Bad ignition switch and starter symptoms are similar. The engine will turn sometimes and will not turn some other times. If it is the switch you will not even here a clicking sound. If the starter is bad you might hear a clicking. If the distributor is bad than the engine will turn every time but it will not start running or will start but not run properly (misfire).

There should be one wire with a small eyelet connector on it, this is the starter field wire from the ignition switch and it should be connected to the small terminal on the starter solenoid marked "S" (this wire is usually purple, but it can also be red or pink)

All of the other wires to the starter including any fusible links, will have a larger eyelet connector on them, and they will all connect together with the battery cable, to the large upper terminal on the starter solenoid, sometimes marked "BAT".

Could be the starter. Also how are your batter connections? Nice and tight and clean?? If so than check the single wire going into the starter. Not the battery cable, but the small wire that goes into the solenoid. Unplug that wire and put volt meter into the connector on the harness side and check for 12V, while you turn the ignition to "START" position. If 12V is present, suspect the starter.

There is either a cable not getting a very good connection, solenoid has problems, or there is a wiring leading to a relay that has a bad connections. How is your ignition? Is it loose or have loose wires?

also check the magnetic switch mounted on the starter housing, is supplied by current from the starting switch circuit of the ignition switch. This magnetic action of the switch mechanically engages the starter clutch assembly and electrically closes the heavy switch which connects it to the battery. The starting switch circuit consists of the starting switch contained within the ignition switch, a transmission neutral safety switch or clutch pedal switch, and the wiring necessary to connect these in series with the starter solenoid or relay.

ITS ROUGH FROM HERE BUT THAT SOUND LIKE A BAD ELECTRICALL CONNECTION......SOMEWHERE IN THE IGNITION SYSTEM.BATTERY,STARTER? OR THE STARTER ITSELF.ARE ALL THE OTHE ELECTRICAL COMPONENTS WORKING?

1st disconnect neg battery cable, then check the connections of all wiring to starter to make sure there's no corrosion, or bad connections. If anything looks corroded, clean it up with fine sandpaper or a wire brush, reconnect and see if it works. If not, remove the starter: disconnect neg battery cable 1st (always), then pos.,then disconnect large cable from starter, then label and remove wires to starter solenoid, some models have a clip holding engine harness (bundle of wires), remove clip and move wires out of the way, remove starter mounting bolts. Reverse to install. Good Luck Countrycurt0
