15000RPM Universal Motorcycle Digital LCD km/h MPH Speedometer Odometer Tachometer Gauge for 8-22 inch wheel

I received this in a timely manner, and it sat on the shelf waiting for me to use it on my project. I finally got around to using it this week. Fabricated a bracket, and got it all mounted. Then I decided to bench test it. First, the wire colors did not match the instructions. Luckily the pin out of the connector is shown, so I was able to figure out which wires go to what. First bad thing, wire from pin 14 is listed as "Backlight 12+" When connected to 12 volts, sparks fly and the whole unit resets itself. So I just left the backlight wire unconnected. Second bad thing, You cannot access the parameter menu. the instructions tell you to long press both buttons simultaneously, and that will bring you to the parameter menu. It does not work. Not matter how I try it, I cannot access this menu. I can change background colors with the left button, and I can change the time utilizing both right and left buttons, but I cannot access the parameter menu. Seems like I wasted my money as it has been months since I bought this and it doesn't work.

the speedometer not working I did litterly everything I can to fix it and finally decided to ohm out the sense circuit on the input speed sensor side and it the supply side is shorted to ground and it's coming from the cluster.I hadn't had time to work on it until recently and have had it a few months sitting on the shelf. They're saying it's out of warranty (although no warranty time is expressed on their page) and they'll only offer a 20% discount if I buy another. Why would I buy another when this one didn't work!?!? Ridiculous!!!!

Arrived in a timely manner for the location its coming from. Upon installation everything worked great the back light on this one looks amazing unlike other cheaper options. After 5 minutes or so The LCD gave out. The Back light gave up and the whole unit quit. Rechecked all connections they are all fine. The LEFT/RIGHT HIGH Signal work so do the other smaller icons. So useless to see my speed or keep track of miles/gas. Cannot return as i cut the cables to make it work on my scooter. Will try with another seller see how my luck goes. The documentation provided has a few errors.(Seller Offered Solution) 5 stars for getting back at me.

Did work at all don’t buy it. Says you can change it to mph but you can’t and the sensor to read wheel speed didn’t work at all. There is no instructions or wiring diagram and it doesn’t come with any hardware to mount it

Sucks

excellent seller. Item was better then explained

I'm having problems with mine, the manual isn't very good. I can't find the wire that controles the fuel gauge on the cluster. Or how to get into the menues to change settings like mph/kph or tire size

I got this, I can use everything in the menu, time,adjust wheel magnet setting, lights, the diagram is 90% ok, says brown wire for backlight but no brown wire, guess my model doesn't need it, ONE STAR BECAUSE SPEEDOMETER DOESN'T WORK!!! 1 magnet or 2 it doesn't pick up anything at any speed! The sensor is dead or somehow everything works except Speedo. Horrible.Is there some special ground I am missing?Does everything need to be plugged in, I don't have 1~5 gear lights so I didn't wire those.Send me a new sensor.
