But then you don't have a safety switch in use and you can start the motor in gear at full throttle. OK, OK, yes you can use the Ford solenoid by just not connecting anything to the second small terminal and making sure the bracket is grounded. STARTER SOLENOID (1 required per assembly) 89-825096 - 89-825096 - SOLENOID More info Unavailable Replaced by 89-825096T. Buy a genuine Mercury Quicksilver or aftermarket part. No need to test it when you've done this, you've killed it. Mercury Marine 50 hp bigfoot (4-stroke) electrical components parts. If you try to use a Ford solenoid on an outboard, that full 12 volt whallop goes to the safety switch and destroys the safety switch almost immediately. A full 12 volt whallop is fed to that resistor when starting. On a Ford, the second small terminal goes to an ignition bypass resistor. The safety switch grounds that terminal when it is safe to start the motor.įord solenoids look exactly the same but are different inside. One is for the wire coming from the key switch. :^As said, car solenoids don't work on those! You don't say what year your 50 is, but you did say the safety switch is on the block. On the first test (key in START, testing small terminal) if you get no voltage, there is whole host of possibilities ranging from dead battery, bad battery cables, bad ignition switch, bad harness, bad connection at harness connector on the key switch or at the engine. If there is no voltage present, the battery is dead or the cables are bad or loose, Voltage at that terminal but not at the other large terminal with the key in the start position indicates the solenoid is bad. The key does not have to be in the START position for this test. If there is no voltage at that terminal, check the other large terminal. If there is voltage there the solenoid is working and the starter or the short cable is bad or the connections are not tight. If there is voltage at that terminal, then check the large post going to the starter. To test the system, have someone turn the key to START while you check for voltage on the small terminal. The other one goes to the ignition switch "S": terminal. If there is only one small terminal, the case of the solenoid must be grounded to the block. If the solenoid has two small posts, one of them is ground and is grounded to the engine block. The cable from the large post on the starter goes to the other one.

The positive battery cable goes to one of them. There are two large posts on the solenoid. ![]() I have no idea why you'd want to do that however. So you can defeat it by simply disconnecting the wires. The kill switch kills the engine when the switch is activated (contacts closed). Re: starter solenoid - testing & wiring diagram
