Put in my batterie to my 72 cl350 and i have power going to the starter magnetic switch but not out, it was working before but now is not. i have tried 3 seperate switches but none work

I suggest checking the ignition switch - I've seen switches do this before, where the switch powers up the starter solenoid but cuts the power to the coil. Test coil output while ign.is in start position - if the voltage is low or non existent, there's your problem!
Best of luck and thanks for using Fixya!!

According with the repairt guide, check this porocedure to REMOVAL & INSTALLATION

1. Disconnect the cable from the negative terminal of the battery.

Fig. Exploded view of the starter motor mounting - 5S-FE engine shown, others similar (click image for zoom)

1. On some early models with cruise control, you may have to remove the battery.
2. Also on some models with cruise control, remove the actuator cover and disconnect the wiring harness. Remove the three bolts and then lift out the cruise control actuator. Remove the bracket from beneath the actuator and put aside.
3. Peel the rubber boot away and remove the nut and disconnect the negative battery cable from the magnetic switch terminal on the starter. Disconnect the electrical connector also located on the magnetic switch.
4. Support the starter by hand and remove the two mounting bolts.
5. Remove the starter from the transaxle.

To install:

1. Place the starter motor in the transaxle and support by hand.
   
2. Install the two mounting bolts and tighten them to 29-31 ft. lbs. (39-42 Nm).
   
3. Connect the connector to the magnetic switch. Place the battery cable on the switch terminal and install the nut. Tighten the nut and position the rubber boot over the cable.
   
4. Using the ignition switch, "bump" the starter over a few times and check for proper operation.

SOLENOID OR RELAY REPLACEMENT
The starter solenoid (magnetic switch) is an integral part of the starter assembly.

1. Remove the starter from the car. Remove the heat insulator from the starter assembly, if equipped.
   
2. Disconnect the wire lead from the magnetic switch terminal.
   
3. Remove the two long, through bolts holding the field frame to the magnetic switch. Pull out the field frame with the armature from the magnetic switch.
   
4. On 1.0 kW starters, remove the felt seal. On 1.4 kW starters, remove the O-ring.
   
5. To remove the starter housing from the magnetic switch assembly:
   
1. On 1.0 kW starters, remove the two screws and the starter housing with the idler gear and clutch assembly.
   
2. On 1.4 kW units, remove the two screws and the starter housing with the pinion gear, idler and clutch assembly.

To install:

1. If necessary, install the gears and clutch assembly to the starter housing. Apply grease to the gear and clutch assemblies and:
   
1. On 1.0 kW starters, place the clutch assembly, idler gear and bearing in the starter housing.
   
2. On 1.4 kW starters, place the clutch assembly, idler gear, bearing and pinion gear in the starter housing.


2. Insert the spring into the clutch shaft hole and place the starter housing onto the magnetic switch. Install the two screws.
3. On 1.0 kW units, install the felt seal on the armature shaft. On 1.4 kW units, install the O-ring on the field frame.
   
4. Install the field frame with the armature onto the magnetic switch assembly and install the two through bolts.

NOTE There is a protrusion or tab on each part; make sure you line them up correctly.

1. Connect the wire to the terminal on the magnetic switch. Install the heat insulator, if equipped.
   
2. Reinstall the starter on the vehicle. Check starter system for proper operation.

You just have to track it down.

The starter switch is doing something, or you wouldn't see any dimming.

Apply power directly to the starter with a jumper cable from the (+) post to the starter. If the starter doesn't turn, have someone help you. have then put the one probe of a volt meter on the housing of the starter motor, and the other on the negative battery. If you measure more than 0.1V, you have a grounding problem.
If there is no grounding problem you are either mistaken that the starter is good, or mistaken that the battery is good.

If the starter turns fine, operate the solenoid manually, rather than using the start button. If the solenoid (which you called the magnetic starter switch) will not operate, since it is new there is a problem most likely with it's grounding. If it operated fine, you have a bad connection between the start button and the solenoid.

It does not take much resistance in the high-current part of the starter circuit [(+) to Solenoid to (+) terminal on the starter] to keep the starter from even turning the engine. 1 ohm will limit the current to 12 amps. 2 ohms lowers the available current to 6 amps, just a little more than the high beam light uses.

Hi!!

I beleive your problem is the starter or the starter selenoid, to make sure, let's DO SOME TESTING, I gather the following info to make it easier.

This test must be performed within 3 to 5 seconds to avoid burning out the coil.
Clutch Pinion Gear Return
Disconnect the negative lead from the solenoid body. Check the clutch pinion gear returns inward. If not perform the no-load test.



Fig. Clutch pinion gear return terminal connections
No-load
Attach a battery and ammeter to the starter. Check that the starter rotates smoothly and steadily with the pinion gear moving out. Check the ammeter shows the correct current. 90 amps or less at 11.5 volts on gasoline engines. If not replace the starter.

Good Luck !!!

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.

The breaker thing is your starter relay and it may be defective or worn out.

These are generic comments

When you turn on your ignition switch, you allow the starter switch to have power. When you press the start button, that energizes a electric magnet in your starter relay which in turn puts the full capacity of your battery at the starters disposal. If this isn't hapening, there is some problem in your relay.

Prove that by jumping those two posts, the ones with the big wires attached. If your starter turns, id suspect the relay. You may have opther troubles as well. Check the relay. BTW - you need really big wire to jump the relay, at least the same size as is going to your starter.

Let me know how you make out.

a

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.
