Check you connections make sure there on the correct way.
You should locate and test the solenoid. Most have three connections. There is a large cable from the battery to the solenoid, from the solenoid to the starter and from the start switch to the solenoid. The power terminals to the battery and the starter are large and have large cables. The starter switch connection is much smaller. Turning the key to 'start' provides a low current voltage to the solenoid causing the solenoid relay to close and power from the battery cable to connect through to the starter. If that voltage is present then the solenoid or the wiring between the solenoid and battery or solenoid and starter is suspect. If that voltage is missing then the starter switch or solenoid feed line may have failed.
Discharged or bad battery Battery cables loose or corroded Defective Starter or starter solenoid Bad Neutral or safety switch
Starter solenoid is bad. I assume you mean engine turning over, not starting, but continuing to turn over after key is released. Disconnect battery cable from post, then replace starter solenoid.
there is no relay for the starter. there is a solenoid (switch) and ignition switch. the solenoid is part of the starter (small cylindrical shape above starter housing. the solenoid has the battery and ignition connections). and the ignition switch is where the car-key goes. you need at least 8v from the ignition to the solenoid for the starter to operate. use a multimeter. otherwise check your starter - battery connections. otherwise replace the starter. otherwise, take off the starter and inspect inside the starter housing. if the starter is clicking but not turning the engine the starter teeth aren't engaging with the teeth on the flywheel. get a manual to the car here: http://www.germanautoparts.com/Books/Volkswagen
it's easy to check the solenoid, put a screw driver across the large nut & the smaller one, and if the starter engages it's the solenoid .make sure the vehicle is in park, or the e- brake is on. ( with key on)
try the neutral safety switch on lower sreering column
Do lights come on when turning ignition on? If so, then you have a bad starter/solenoid/relay. If not then, you may have a bad battery or connection or ground.
Could be: Seized engine Weak battery loose or corroded battery cables Bad starter solenoid Bad starter Bad neutral or clutch safety switch
Could ba a bad starter solenoid - not releasing causing starter to over heat
make sure battery cables are tight
I had the same thing happen to my ford 351. I had to tap on the solienoid to get the starter to stop turning over. On this particular truck the solenoid is mounted under the hood.On alot of chevys the solenoid is mounted on the starter itself.
The starter is just one part of the starting circuit that includes the key switch, battery, solenoid, and wiring. If any one of these parts fails, the starter won't activate. If you hear a click from the engine compartment when you turn the key to 'start' then you have a good circuit to the solenoid. The click you hear is the solenoid pushing the starter gear into the flywheel. Normally the starter motor starts turning at the same time to rotate the flywheel, which is connected to the crankshaft. If this is not happening, make sure the battery is fully charged. Check the engine compartment for burned or missing wires between the battery and the starter, or loose connections. If you hear a whirring sound from the engine compartment when you turn the key, it may be the starter gear is not engaging the flywheel and the starter motor is turning. Most modern cars have the starter and solenoid in one unit. Remove the starter and take it to an auto parts store to have it tested. Also check the gear while you have it out. Broken or worn teeth on the gear or flywheel will prevent it from turning the engine. --mark
