Likewise people ask how do you test a starter solenoid on a Mercruiser. Use a new battery and set it on the ground next to your motor.
Yo did the testing correctly.
Mercury outboard starter solenoid test. How to Test a Mercury Outboard Solenoid. The solenoid on a Mercury outboard motor is used to actuate the starter. It is nothing more than a remotely activated switch.
It takes considerable amperage to operate the starter which in turn requires a large diameter wire to carry the load. Likewise people ask how do you test a starter solenoid on a Mercruiser. How to Test a Mercury Outboard Solenoid.
Set the voltmeter to 20 volts. Ground the black lead on the voltmeter to the block and touch the terminal end of the large red wire at the solenoid with the voltmeters red lead. How do you test a starter solenoid on a Mercury outboard.
How to Test a Mercury Outboard Solenoid. Set the voltmeter to 20 volts. Ground the black lead on the voltmeter to the block and touch the terminal end of the large red wire at the solenoid with the voltmeters red lead.
Check the small wire on the solenoid by removing it with a small wrench. Have your assistant turn the key to start the engine. The voltmeter should read 126 volts or more.
Listen for the solenoid to click and the starter to spin. If you do not have 126 volts and the starter does not spin you have a problem with the ignition switch. Next connect the positive voltmeter lead to the outgoing large solenoid post and the negative voltmeter lead to the starter positive post and hit the starter switch.
A reading of over 2 volts indicates a bad wire between the solenoid and the starter. To test a starter solenoid connect a test light to its output terminal to see if it has a current. If the light comes on youll know theres power going to the solenoid.
If it doesnt check your battery. When you know you have power check that its being transferred properly by switching the red lead to the solenoids lower terminal. A quick test of your wiring would be to bypass it all by jumping from the hot lead on the starter to the little terminal your starter wire is attached to.
Because I was having so much trouble tracking down my problem I got a remote starter. Test a starter solenoid with a multimeter. Set the multimeter dial to continuity mode connect the multimeter probes to the solenoid terminal post the one used to connect to the motor body and the solenoid shell.
If there is a resistance then the holding coil is good. If the resistance is zero then the circuit might be shorted. WHAT IS WRONG WITH MY MERCURY OUTBOARD.
REPLACING SOLENOID STARTER IGNITION AND BATTERY - YouTube. Turn the ignition key to start. If you hear a clunking noise coming from the starter its the solenoid trying to do its job and there is probably nothing wrong with it.
No sound indicates a possible solenoid problem that requires further testing. Make sure the multimeter is turned to the proper volts scale and the boat transmission is in neutral. Outboard Motor Control Wiring Part 4 - Starter Motor Solenoid Troubleshooting - YouTube.
4 Common Starter Solenoid Problems. 1The starter solenoid failing to reset even upon releasing the starter button or turn the car switch in the off position the starter continues to operate. 2The sucking action of the starter solenoid failing from time to time.
3The drive gear failing to restore in time leading to it being driven by. Check the master solenoid by touching the test light to the heavy post to which the red wire from the slave solenoid attaches. It should energize as the helper turns key to Start Keep the key in Start and touch the post just below which is attached to a copper strap leading down into the starter.
Here is a quick test to see if the boats cables are OK. Make or buy a set of good 2 gauge marine battery cables one red and one black. Use a new battery and set it on the ground next to your motor.
Attach these test cables directly from the new battery to the engines starter solenoid positive red and a good engine ground negative black. The contact located inside the starter solenoid activates a circuit to open and allow electrical current to transmit from the battery to the boats starter. This in turn starts the outboard engine.
A faulty solenoid could prevent the starter from getting power so ruling this out first before condemning your starter is a must. Yo did the testing correctly. Replace the start solenoid.

I have a 1982 90 hp Merc outboard and I wish to replace the starter as it seems to have a heavy draw down and will barely turn over the engine as well when the key is engaged the. UNIQUE DESIGN- Stepped mounting plate solenoid can be used for the starter or power trim system on a wide variety of Mercury and Mariner outboards and Mercruiser stern drives. EXCELLENT SERVICE- We are strict with quality control standards to Build and test.
Our Trim Solenoid Relay Switch comes with 24 months warranty. STARTERS ARE LISTED HERE These solenoids fit many different motors. If you cant visually match your solenoid to one of these please contact us with your serial number so we can match the correct one to your motor In many cases the original part number is stamped on the underside of the bracket which you can reference below.
The final test is to touch the probe to the post that connects the solenoid to the starter. Again have a helper turn the ignition key. If the test light turns on the solenoid is working.
Either theres insufficient power low battery to run the starter motor or a problem with the starter motor. Mercury Outboard Solenoid Forum Topics. Mercury Outboard Parts Powerheads Mercury Propellers.

Plumber87 yes you can test that type choke via a battery. It is nothing more then a coiled wire that produced a magnetic field to pull in the plunger.
Just dont keep the voltage on it. It is designed for a short usage and not continuous. But reading you post you dont have to remove it to test it.
