1992Cadilac fleeteood brougham got new starter done put battery im and the car tries to turn over with no key in ignition and negetive post sparks battery


It sounds to me that the small post or wire going to the starter is touching the large wire. The large wire is the positive battery cable and the small wire is the signal wire from the ignition switch. If the two are touching each other the starter will engage as soon as power is applied and circuit is completed at the battery.

Wire 253 holden boat motor starter alternator coil basic diagram


batter positive to one big terminal of the starter solenoid--large wire as in a car ( the other big terminal will have a wire from it going into the starter)
a wire from the start point of the ignition switch to the small terminal of the start solenoid .( This to energize the starter solenoid to start the engine.) a large wire ( 30 amp capacity ) from the positive terminal of the battery going to the BAT terminal of the alternator the plug in the back of the alternator will go to the battery light or ammeter.. wires from the start and run positions of the ignition switch to the coil. One to provide power when the starter is engaged and the other from the run position to provide power to keep the engine running
basic but it will work

We put the new starter on today, and the car still won't start. We are thinking it's the starter relay. What else can be wrong with the car? can you please help us we depend on that car. Thank you


There is no starter relay shown in a wiring diagram. The only thing between the ignition switch and the starter solenoid is the park/neutral switch (or the clutch pedal position switch on manuals).

Do the warning lights and gauges come on with key on? That would verify power is into the switch and being sent out. The small purple wire on the starter solenoid should have power on it when the key is held in start position. If it does, recheck your starter and battery connections. When the purple wire energizes the solenoid, the starter motor should crank the engine.
If no power on the purple wire in start, check the neutral safety switch or the clutch switch if a manual. The start wire out of the ignition switch is a yellow wire, and the wire from either safety switch to the starter solenoid is a purple wire.
(The power to the ignition switch is from the 50 amp Ignition fuse in the under hood fuse block.) See? The positive battery cable is connected to the starter, but not to the starter motor. When the key is in start, the hot purple wire energizes the solenoid and the battery cable is connected to the starter motor.

Starter issue on 1988 dodge w150


check the brown(small wire) to the starter soleniod to make sure it is not touching the large red wire.. if it is ok, than try removing the relay before connecting the battery.. if it still cranks, it may have an internal fault with the starter/solenoid. if it doesn't crank, than problem is with the ignition switch or a remote starter(if equipped)

STARTER STAY RUNNING AFTER CRANKING THE IGNITION!


It is due to one of 2 things. The ignition key can still be sending the start signal to the starter relay through the small wire in the Relay solenoid; or the starter Relay is stuck after it gets the signal from the key and the key is correctly in the RUN position.

You would need to put a voltmeter on the small wire on the starter solenoid. The Relay should not connect the battery to the starter without this small wire attached to it.. If this wire is off and the
starter gets power, the relay is bad. If you test the small wire for power, it should only have power in the START position. The small wire should be powerless in any other position.

If the small wire has power at other times, the ignition switch is bad.

Please rate my info.

Starter activates when battery wire connected and starter is grounded to frame with or without solenoid wire connected. No short between posts on new starter. Only does it when the power source is from the...


sounds like you are hooking up the starter wrong. the positive goes to the starter main terminal from the battery. the ignition wire goes to the s on the solenoid, which activates 12 volts when the ignition switch is turned on which causes a magnetic field
inside the solenoid and joins the connectors
in the solenoid to the main positive wire from the
battery to the main starter unit brushes/armature inside the starter unit. If you have a constant
12 volts from the ignition wire it will keep the solenoid engaged. If you put the main positive wire on the wrong solenoid terminal it will immediately engage the starter. try putting the main battery wire to the correct terminal or perhaps check the ignition wire for a short or constant voltage to the solenoid.

No starter response when key is turned over. new starter and battery. all fuses and relays good. only thing left is ignition switch?


The starter is malfunction at this time. it could also be a ignition issue as well. here is a quick starter test procedure that will help you troubleshoot a bit.

Step 1
Check for 12 volts on the large wire attached to the top terminal on the starter relay. It should have battery voltage. If not, the battery, terminals or wire is bad.


Step 2
Check the small wire on the solenoid for power when the key is in the start position. Remove the small wire on the solenoid and have a helper hold the key in the start position. Check the wire for battery voltage. If there is voltage, the starter is bad. If there is no voltage, replace the wire.


Step 3
Check the fuse in the fuse box under the hood on the left fender well. If it is good, check the relay by pulling it out and checking for power at one terminal with the key off. If there is no power, the problem is in the fuse box between the fuse and the relay. If there is power, have the helper hold the key in the start position once again and check for power at another terminal from the ignition key. If there is power, the relay is bad. If there is no power, the starter circuit is suspect.


Step 4
Check to see if there is power to the neutral safety switch if there is no power at the relay. Use the voltmeter to check for power with the key in start. If there is power going in, check for power going out. If there is no power going in, the security system or ignition switch is suspect. If there is power going in and none coming out, the switch is bad. If there is power coming out, the problem is between the neutral switch and the relay.


Step 5
Remove the cover on the bottom of the steering column. Check the solid yellow wire for power when the key is in the start position. If there is no power, the ignition switch is bad.
