A wiring diagram is a sort of schematic which utilizes abstract pictorial icons to reveal all the affiliations of components in a system. Circuitry diagrams are made up of 2 things: icons that stand for the parts in the circuit, and lines that stand for the links between them.
From circuitry diagrams, you recognize the relative place of the components and also just how they are connected. Wiring layouts mainly reveals the physical position of components and links in the developed circuit, but not necessarily in reasoning order. It highlights on the layout of the wires. Schematics stress on just how circuits work realistically.
To check out a wiring diagram, initially you need to know just what essential aspects are included in a wiring diagram, as well as which photographic signs are used to represent them.
The common elements in a wiring diagram are ground, power supply, cord and also connection, output devices, switches, resistors, reasoning gateway, lights, and so on. A line represents a wire.
Wires are used to connect the components together. There must be a tale on the wiring diagram to tell you what each shade indicates. Usually circuits with greater than 2 parts have 2 standard types of links: series and parallel. A series circuit is a circuit where components are linked along a single course, so the existing circulations with one element to obtain to the next one.
In a series circuit, voltages add up for all elements linked in the circuit, and also currents coincide via all elements. In a parallel circuit, each gadget is straight connected to the source of power, so each gadget gets the very same voltage.
The current in an identical circuit moves along each parallel branch and re-combines when the branches satisfy once more.
A great wiring diagram requires to be technically proper and clear to review. Deal with every detail. The representation ought to reveal the right instructions of the positive and also unfavorable terminals of each part.

Utilize the best icons.Before you tear anything apart or replace wiring and switches, test it out; first by visual inspection by pulling back and forth on the wires while operating the switches and then test with a meter.
At the commander switches, the red wire will always have 12 volts. The green wire gets 12 volts when the trim toggle is held down. The blue wire gets 12 volts only when the toggle is held up or the trailer switch is pushed in. The purple wire is part of the limit switch circuit.
These are the trim position and limit switch wires. Pull them apart and inspect; they should be clean and tight; reconnect them. If necessary, trace the wires to the front of the engine near the slave solenoid. One wire is grounded near there and the other is connected to a terminal.
If you don'tP get a voltage reading at the terminal junction, apply 12 VDC to see if the trim gauge moves. If it does, check for voltage back at the trim pump connections. If no voltage there, apply 12 VDC there to check gauge movement.
This plug can vibrate loose and cause your problem. Pull it off and see if the pins are clean and not corroded; reconnect it. The RED wire in the plug sends 12 volts from the pump assy. Did you check the switches with an ohmmeter? To test the limit switch circuit, lower the OD to the down position and slowly raise it with the trim toggle up until it stops.
Then measure the distance between the trim cylinder attaching bolts.

If the distance is approx. Pull them apart; they should be clean and tight; reconnect them. Each solenoid has three wires and the buss bar connected to it.
The bases of them have a black ground wire and a small blue wire to one and a small green wire to the other. On top of each solenoid, the large BLUE wire from the pump motor attaches to a large copper stud with the solenoid that has the small blue wire at the base while the large GREEN wire from the pump motor attaches to a large copper stud with the solenoid that has the small green wire at the base.
The other copper solenoid studs are connected together with a copper buss bar. One of the two studs will also have a funny looking amp fuse attached to the bar. The large RED wire from the battery connects to the amp fuse.
This large red wire is the power for this buss bar. A small RED wire attached to the bar stud sends 12 volts to the switches which in turn sends the 12 volts to the solenoids which turns on the pump motor. The dark color comes from heat generated inside of the solenoid by the contactor because it is arcing like welding similar to points wearing out.Variety of mercury trim motor wiring diagram. A wiring diagram is a simplified traditional photographic depiction of an electrical circuit. It shows the elements of the circuit as simplified forms, and the power and signal connections between the tools.
A wiring diagram typically provides information regarding the relative setting and also arrangement of gadgets and terminals on the gadgets, to assist in structure or servicing the device. A photographic layout would reveal more information of the physical appearance, whereas a wiring diagram utilizes an extra symbolic notation to highlight interconnections over physical look. A wiring diagram is typically made use of to repair issues as well as making certain that all the connections have actually been made which whatever exists.
Click on the image to enlarge, and then save it to your computer by right clicking on the image. A wiring diagram is a simple aesthetic representation of the physical links and physical format of an electrical system or circuit. It shows how the electrical wires are adjoined and also could likewise show where components and components may be attached to the system. Use electrical wiring diagrams to assist in structure or manufacturing the circuit or electronic tool. They are additionally valuable for making fixings.
DIY lovers make use of wiring diagrams yet they are also usual in house structure and auto fixing. A home contractor will desire to validate the physical area of electric outlets and also light components making use of a wiring diagram to prevent expensive blunders as well as developing code violations. A schematic reveals the plan as well as function for an electric circuit, however is not interested in the physical design of the wires.
Circuitry diagrams show exactly how the cables are linked and where they ought to located in the real tool, as well as the physical links in between all the components. Unlike a pictorial diagram, a wiring diagram uses abstract or simplified forms as well as lines to reveal parts.
Pictorial diagrams are commonly photos with tags or highly-detailed illustrations of the physical components. If a line touching another line has a black dot, it means the lines are linked. A lot of symbols used on a wiring diagram look like abstract versions of the real items they stand for. A switch will be a break in the line with a line at an angle to the cord, a lot like a light button you can turn on and also off.
Don't overlook anything. Be sure to check the wiring to the bottom of the relay sockets for corroded and broken wires! The up and down relays are identical, so switching them back and forth is OK. When switching the relays, see if the problem changes directions. This is because power to the trim-tilt pump motor is in series with BOTH relays. The direction that the pump runs is determined by the direction of the current flow through the relays.
This can be confusing to troubleshoot because there are a total of 10 terminals involved. When you activate either relay by pressing the tilt switch up or down, the internal solenoid winding becomes energized you should hear the relay click and the series ground contact is broken and toggled over to a 12 volt input terminal 87 - the thick red wire.
See diagrams Wire jumper configuration to completely bypass the relays and make the motor trim UP: On the UP relay, place a jumper between terminals 87 and 30 On the DOWN relay place a jumper between terminals 87A and 30 Wire jumper configuration to completely bypass the relays and make the motor trim DOWN: On the up relay place a jumper between terminals 87A and 30 On the down relay play a jumper between terminals 87 and 30 When replacing relays, always replace both at the same time.
One should be green and the other blue. You will probably be able to find a quick disconnect plug near where the wires exit the outboard engine cover that you can disconnect. The motor should run in one direction or the other. Now reverse the wires and the motor should run in the other direction.
Troubleshooting: Trim/Tilt Does not Work
This will at least tell you if the motor is operating, so that you will have a better idea of what the actual problem might be. It is worth repeating here: The voltage and current flows through BOTH relays, therefore when testing be sure you have a complete circuit.
Question 17 days ago. I have a 60 HP Johnson that the trim and tilt stopped working all of a sudden. I have replaced the relays and checked the old splices and replaced the remote switch on the throttle handle with a 3 way toggle switch temporarily.
The tilt motor works after replacing the switch until I wrap the connections with electrical tape and secure the switch to the throttle control handle. Then it just quits working.Wondering "Where-'n-'Ell" to get great parts for your outboard?

A circuit is generally composed by several components. The other thing which you will get a circuit diagram would be traces. Lines in the diagram show how each component connects to a another. The arrangement is also not logical, unlike wiring schematics. Diagram only reveals where to place component at a place relative to other components within the circuit. One thing you have to learn before reading a circuit diagram would be the symbols. The most common elements are capacitor, resistor, and battery.
Additionally, there are other elements like floor, switch, motor, and inductor. Sometimes, the wires will cross. Injunction of two wires is usually indicated by black dot to the intersection of two lines.
There will be main lines which are represented by L1, L2, L3, and so on. Colours are also utilised to differentiate wires. Usually, there are two chief types of circuit connections. The primary one is known as series connection. Because of that the electrical current in each and every component is similar while voltage of this circuit is complete of voltage in each component.
Parallel relationship is much more complicated than the string one. Unlike in series connection, the voltage of each element is similar. It is because the component is directly linked to power resource. This circuit contains branches which are passed by different electrical current levels.Look on the back of the gauge and see if there is a brw wire there.
