Using the hitch receiver and adapters with the bike's axle to make a tire mounting platform.
WRR AC RIPPLE TEST AT BATTERY
zhlédnutí 1,3KPřed 6 lety
Testing for ripple voltage at the battery terminals WR250R with good battery and new stator. 2 good quality meters agree, cheap meter is way off.
WRR Pressure Sensor Test at ECU
zhlédnutí 560Před 6 lety
Yamaha WR250R. Voltmeter probes to Pink/White ( ) and Black/Blue (-) wires at ECU. Note that voltage transitions during throttle snap are smooth and never jump to zero or five volts.
2006 CRV Voltage During Start & Run
zhlédnutí 1,1KPřed 6 lety
Good test results of charging system. Note that starting voltage stays well above the minimum acceptable limit of 9.6 volts (As shown by the stored minimum voltage of 10.64 at :34 in the video) and that the voltage remains quite steady as the RPM is increased. This is the original stock alternator and a one-year-old battery.
if you're having a problem starting your bike can you do this same test with the key in the on position to actually get the bike running
what position is the the red run stop rocker switch in?
What are the symptoms of a bad MAP sensor on the WR250R please? Thanks!
I had a huge doubt if my radiator fan is working.. thanks to you i cleared my doubt. Keep up the good work 👍
Hey sir , i need your help , my bike showing 5.5 error code , what is the meaning of that error code
wtf
thanks for the info, but not working on my wr450f '18
since this is ac signal can i use to to a transformer to step up 5v to 250v to make a cdi
"to erase that I turn the switch on then off"? What switch? also the service manual says to disconnect the fuel pump wire harness. I think there is a test that requires pressing the starter, so disconnecting will not pump gas to the injectors.
How do you exit diagnostic mode
How to adjust the speed setting to change the gear ratio?
Thanks. I confirmed that my fan works. No electrical issue. I noticed fan never goes on since the purchase brand new from the dealer. What is the min temperature that should turn on the radiator ? R2018. Thanks
I've just been messing with this myself - had my first overheat in 12 years yesterday (2008) and my fan nor light never came on - used to run all the time, especially on trails and have seen the light once or twice. Using a potentiometer, I'd set it until the fan came on, then go into diag. and see what temp it was reading. It seems the fan comes on around 222F and the temp light around 242F. Running at idle, smelling the coolant getting hot, I read 185F max, so I think my coolant temp sensor is to blame. I"ll pull it this weekend and test it in some boiling water, but I'm going to have the spare on hand anyway.
OblivionRatula good idea thanks
OblivionRatula Do i need to drain oil or coolant to replace the sensor ? Is it actually oil or coolant sensors ? - I wish to find some online doc about engine repairs. Just in case I bought this “Brand: MOTOALL MOTOALL Temperature Thermosensor 179700-0220 8CC857900100 5PS857900000 Thermo Sensor for Yamaha TEMP 8CC-85790-01-00” on amazon. Not sure if that is BS but that what I went for.
@@michalaugustyniak6449 Sorry man, I forgot about this comment because I didn't know the answer at the time. Yes, the coolant will come out when you pull the sensor. I was due for a flush/change anyway. I also swapped the thermostat while I was in there. Can't say if it's the right sensor, I just ordered the OEM from Partzilla. Got my bike happily blowing hot air on my leg at lights again. Good luck!
Hey bud how did u exit diagnostic mode
Greetings Len Couch. From this information, I should be able to log it to the digital pins of Arduino (5V) by adding a high ohm resistor, a zener diode (to limit (+) voltage to 5V max) and a normal diode (to remove the (-) voltage). Am I right? Based on the electrical diagram, it is the Blue(+) and Green(-) wires. I have a basic knowledge on electrical engineering. Can you advise what resistors, diodes and wiring diagram please? The signal circuit has to be of high impedance so as not to change the pickup signal. Am I right? I'd like to log this information to determine RPM and TDC/BTDC. Thank you.
I am not familiar with Arduino inputs. You mention "digital pins". The DRZ signals are all analog, and would require an Analog to Digital converter between the signal from the bike and the Arduino if it does not accept analog signals directly. As far as your idea about using the zener to reduce voltage, it may decrease the signal to noise ratio of the circuit because of RFI noise near the signal floor. A simple L-Pad design should work better, Link here:www.electronics-tutorials.ws/attenuators/l-pad-attenuator.html
Thanks buddy!
How did u exit diagnostic mode
@@dereckrodriguez9688 I have since sold my bike but I think I just turned the key off and on again
@@groovyshoos5200 thanks man I figured it out. Was on my way to buy one and wanted to check all those codes to see if there was an issue. Btw what’s the black box on the left rear side of the bike. It’s where passenger pegs would be on a normal bike
After resetting the Fault Codes(This video ends at that point), when I reach the Diagnostic Mode, it shows Er_4. How to fix this ?
Me too, what did you do bro
@@_davidsuciu It was ok automatically as I can remember, it was long time ago bro. If I will find something, I will let you know.
How did u exit diagnostic mode
Thank you for this. What actualt voltages did you meassure on this pickup? Its hard to tell from the video. Thanks.
The screen capture from 0:39 to the end is at a 1 volt per division scale. Therefore the base waveform is showing between 2.0 and 2.5 volts PEAK-TO-PEAK, and the trigger pulse shows about 5 volts. I don't know how a voltmeter would interpret the voltage since it is a complex waveform.
Is this with the CDI box hokked up to the sensors? I would expext alot higher voltage. Towards a hundred volt.
@@Tobbera Remember that this is only at cranking speed. Being a VR design, the voltage will increase as engine speed increases. FYI the CDI output signal to the ignition coil is about 225 volts peak. Screen shot here: i.imgur.com/G9rjt9X.jpg
@@lenarama1066 The CDI output to the ignition coil when compared against the pickup signal could be used to determine spark advance timing right?
@@mohammadshahrilbinbakar8319 Correct.
Thanks. There is two VR pickup sensors. Which one is this?
This is the external sensor that reacts to the magnets on the outside of the flywheel and provides trigger (timing) signals to the CDI box.
Good job
Cheapo meter dosent have the brains to calculate rms
Very useful to know! Thanks for posting this!
Sweet video! Subbed!
Great video!
Thanks for this. Do you have a list of what these numbers correspond to?
I can e-mail you a copy of the service manual if you wish. Send your request to lenarama1066@yahoo.com.
hey buddy that was a great video my fan quit working today on my WR250r and I'm trying to figure it out didn't know the WR could do a diagnostic test ( very cool) thanks for sharing ,,,LIKED ( thumbs up )
same here...fan makes an icky sound
now want start
my wrf250 indicators broke of
Any ideas, why I can't enter the diag? I followed the instructions, check lights go on, go off but the red one (engine temp.) and green one stays on. Still holding the buttons (longer than mentioned time), but nothing happens. My fuel pump doesn't run after turning the ignition switch on, therefore I can't start the engine, nevertheless the starter is running. Aslo tested the fuel pump, it's working when I put voltage on the connectors.
Is the engine stop switch on the right handlebar in the "ON" position? It should be on when entering the diag. mode.
lenarama1066 yes, yesterday I put my ecu in my friend's wrr and found out, my ecu is dead.
I saw in another video that some ECU plugs (under the seat) don't have the black ground cable connected. Without the black cable being connected to ground you can't get into Diag mode.
Thanks for posting this. Helped a lot.
Hello i need information for wr450f 2006, thanks. aruzvado@yahoo.com
Hello i need information for wr450f 2006, thanks. aruzvado@yahoo.com
thank you, it helped me a lot
Greta little video... It could also be a faulty solenoid, power gets to it, but cant pass trough becuase its worn and corroded/sooted on the inside :)
Looked all over for something like this. THANK YOU!
Thanks, nice info, very helpfull
Thanks, much appreciated. Is there a complete list of all the codes somewhere? :)
Jens Eskildsen I can email you a PDF copy of the complete service manual. Reply with your e-mail address to lenarama1066@yahoo.com
lenarama1066 great video. could I also get that manual email?
Frank Fish Would you please email to me too?
Possible to send me a copy also?
Hello, my wr 250x on: di:01 remains at 15 , and then does not move , that problem I have ? The bike is working well , Thanks
You have to roll the throttle
I bought my wr without a speedo. So I bought an oem one used with 4800mi. Plugged it in and got err1 meaning no signal from ecu. Here is only 1 connector behind the headlight but there is 3 connectors on the speedo. Does yours require only one connection?
Good work, very useful video. Thanks for posting
Nice job! Simple, easy to follow explanation of how to get into the diags and how to move around. Thanks!
