Yanmar Starter Wiring Diagram

Yanmar Starter Wiring Diagram – I started my Yanmar (3JH4E) after winter storage and it cranks but won’t run. The key was in the “on” position and the oil level gauge was working. After several attempts, I found that if I turn the engine on and immediately switch it to the “OFF” position, the engine runs normally, but nothing works. Fire/play function as usual. To stop, I put the engine on “RUN”.

I had this problem last year after storage and I suspected the starter switch, it was fixed before I went to replace it. All connections appear to be in good condition. Has anyone seen this before?

In the “ON” position, the engine does not continue to run. To turn off the engine, I switch the switch from “OFF” to “ON”. To start the engine, I turn the key to the “Start” position, turn it on, then quickly turn it to the “OFF” position and leave the engine running. The strange thing is that the engine did the same after storage last year, then the problem disappeared. I had no problems all season.

My guess is that the on position is shorted to cut off the fuel. Turning the key off isn’t really meant to stop the engine, so I wouldn’t be surprised if it continued to do so. It will automatically stop due to power failure.

Once you’ve sorted this out, you might want to check your conversion rates. The switch is not designed to turn off with the engine running, so hopefully you didn’t screw anything up there.

Is your pump leaking? And somehow the OP killed himself?

Eds-Therapy says: I don’t believe it Click to expand How do you turn off the engine when the normal switch works? The manual says you have to press the button on the dash to turn off the engine. This usually indicates a power failure and I think that wire is shorted to the on position wire. Do you have a button like this or a cut of buttons?

So looking closer at one of the wiring diagrams in the manual I suspect that the problem may be caused by the brake itself closing (if installed).

Item 11 is a switch, but the rest of the picture says that the “i” switch connects the 30-pin AC connector. Once connected, the fuel supply switch (item 12) is activated. Switch to any other position to remove gauges, lights and switches from the circuit. Since you say the motor shuts off as soon as the switch is turned on, maybe that switch is just stuck and closed. It may have been that way at the beginning of last season before it got warm enough to melt some moisture or loosen the joints.

It’s a very good idea! Normally when “ON” is selected. I hold the “STOP” button and it closes. The possibility of moisture in the key is very high and it should be dried a little. I would like to know if I can temporarily remove the brake switch to fix the problem? which begins to control everything. Well thank you!

Start by physically looking at the actual table……check the wiring and make sure things are secure. It’s like a crossed wire. Sometimes you can see a problem and solve it.

It sounds like you have a fuel shut off solenoid that shuts down the engine. I think the solenoid may be grounded or shorted. It could be a solenoid, maybe a switch (motorless diesels) or it could be a wire.

The electric motor went out……..he has a new switch….bet he’ll fix it. It’s a simple matter. Yeah, I’ve always heard that if you damage the alternator, the key won’t turn off. I have the same panel for the 4JH4E.

These fuel saving systems are installed and operated by computer systems on cruise ships – what will you do when the technology fails? Comfortable? The electric motor appears to have failed in “idle mode”. It seems to be more efficient than the “no stop” mode as I can still find a way to neutralize and reduce fuel. Does anyone know the instructions for this Yanmar engine with an electric motor? As if nothing was pulling the table and twisting the wires. Imagine doing it in a horse-drawn carriage.

Just an update on the matter. I went down on Sunday and started. The engine ran in the “ON” position and ran normally. I didn’t touch the wire that Sunday as planned. Everything was normal. I tested it several times and it was the same last year. Problems were detected on the first day of storage. It resolved itself in a few days.

If you have a fire extinguisher, you can turn it on and put out the fire. Maybe the fire extinguisher switch is open when it’s cold and the hysteresis keeps the switch open until it warms up. (press the bottom of the switch) There is a switch on the cart that allows the engine to start.

Jake N Eggs story. The pressure in the automatic engine should be low. The weather was hot and the band was heavier. Try the scroll button on your desktop next time. I was looking to add a relay to my Yanmar 3GM30 starter circuit to prevent excessive load from passing through faulty switches and billions of years of grand parents.

In the image below, it is not clear how the hardware itself will turn on after this mode.

The current setup has a 6mm square wire (red) from the key switch to the large nut on the solenoid (where the starter is powered). This is protected by a 30a fuse.

Then a 6mm square white wire runs from the terminal block on the solenoid to the switch terminal.

Assuming your existing assembly is still intact, all you have to do is remove the white wire from the terminal and connect it to the positive side of the driver coil of your new relay. If you have the negative side of the activation coil connected to ground, your new signal will be activated whenever the switch is on and pressed.

Of course, you still have to connect the new connection from +ve (eg 30 A fuse line to the starter electromagnet).

The red wire supplies power to the device through a 30 amp fuse. Then go to the key first..

All of this will remain after adding new code. The fact is that now the new relay will also receive power.

Ah, that makes sense. The confusion is that the picture shows a jumper to 30. I have the first red wire and a fuse in it.

In the picture, only two wires are connected to this side. One on the rocks and one to register 30 on the board.

This is what your son says, at that time I have to install three wires. 30 amp main red wire going straight to the switch. High performance battery cable and a new cable in this case called jump to 30.

I did this to myself. This was quickly fixed and it has been fine ever since.

I have a new starter and solenoid. 6mm square wire to replace the white and red wires from the ignition switch/button. 8mm2 wire to the relay (for pins 30, 85 and 87) but it still clicks when I press the switch.

30 goes to the electrical terminal, where the battery wire and the red wire from the key switch also go.

The batteries are already charged and the engine starts, it actually started to push for the first time after installing the relay, but it turned off and restarted, I clicked the solenoid the same way I should improve with this module

I had similar problems. The fire is burning
