2007 EC 300 Speedo
 

Does the factory GG speedo for a 2007 EC 300 run on AC or DC? Does it use a battery? (referring to a battery in the speedo, not a bike battery)

Thanks

Is that the TrialTech version? If so, it runs on AC or DC and has an internal CR2032 battery as well.

I don't know who makes it. Here are pics of front and back. A label with "BE250634005" is on the back. "Made in Taiwan", "10R-022812" and E13 are cast into the plastic on the back.

If this is the Trialtech speedo, where does the battery go?

Any ideas where to find a manual?

Found it. Googling 10R-022812 took me here. http://www.acewell-meter.com/images/V1manual.pdf

Manual is at: http://www.acewell-meter.com/images/V1manual.pdf

It's an Acewell ACE 39xx computer

Seems to run on 12VDC.

Anybody have a document that describes the inputs? Nothing in the "manual".

the red&white wire is for power i have mine hoocked up to a 9 volt battery i had it hoocked up to the ignition but it surged like your headlight does i have the 30 watt ignition or 2k2 i think the green and black wire is for your speedometer you should have gotten a 4or 5 foot leed that threades into your front brake caliper bottom and a pickup attatched to your hub the yellow wire is for your tack it ataches to the coil where the spark plug wire boot comes out of cant remember whitch one once i got every thing else runing i just touched the wire to the diferent conections until it worker sorrey for the bad spelling done didnt finish high school hope this helps ihad to do the same with my bike figure it out

Victory!! I got a PDF file from ACEWELL that shows the connections for the 2007 GG speedo. Let me know if anyone needs it.

Would you email it to: deltron@swbell.net

Thanks, Bill.

Speedo now working
 

Finally got the GG/Acewell speedo set up. The Acewell pinout document shows that it had to run on DC so I had to get 12v DC on the bike. Bought a TrailTech rectifier/voltage regular (7003-RR150 ) and capacitor (040-CAP56) and a 10 amp fuse. By the way, if I were doing this again I'd get the smaller capacitor (040-CAP27). The CAP56 is HUGE. I got AC from the white coil wire I found taped up in front of the tank. The yellow lighting coil wire that would run the lights (if it had them) on the bike was left untouched. Everything works great. The capacitor even runs the speedo for about 5 minutes after shut down, letting you do set up with the engine off. The Acewell requires an external 9v battery for the clock so I also wired that up.

The speedo provides MPH, RPM, trip 1 odometer, trip 2 odometer, odometer, max RPM, max MPH, average MPH, clock, total time, run time, shift light.

Mounted on rubber with nylon bolts. Red circle is tach pickup.

Made a wire loom with 4 positive and 4 negative terminals. May want to run a GPS.

Finished install. Note 9v battery upper right.

I would be very interested to get a copy of the .pdf showing the connections
for the Acewell computer. I went to their web site and only found the users
manual. Nothing showing the color coding or what connectors feed what
information to the computer.
I picked up a used "take off" from an 07 TXT and it is missing the tach and
temp sensor wire connectors.
That and I don't know which wire to feed it 12VDC to get the clock and
LCD back lighting to work.
I would appreciate it very much if you could send it by PM here or send
it to my earthlink acct. jjwallace@earthlink.net it will bounce with a spam
message because you are not in my address book. Ignore the warning.
Thank you, Jeff So-Cal.

Good god man that capacitor is HUGE! Who told you to use that? It probably holds enough current to do some arc welding ! Looks like something from a 1960 tv set. I'm sure something the size of the tip of your finger would have worked, plus I don't think you needed DC, although it would be nice for the gps power.
The same unit works on my 2006 and don't think there is any dc in the system. I'll have to hook up the 9V battery though so the clock doesn't reset every time.
