Medallion Speedometer

Well Happy Birthday to me :) My wife asked me what I wanted for my birthday and I told her a Medallion Speedometer, and we picked it up today from NY Cycle City. Note, they have 4 left in stock. My question to anyone that installed one of these before. Do I need to remove the gas to install this speedo on a 2008 Ridgeback?

I don't really see why you would need to do that.
Couple screws, pull the guts, plug the new speedo in and put it back in.
Well the best way was to remove the tank to run the wire to the battery. This is not a direct replacement for the old Speedo where you just remove the old one and plug in the new one. And once you install this one there's NO GOING BACK to the old Speedo. Cause you have to break the 3 wire connector and replace it with the included 4 wire connector.

Not that cut and dry as you would think and hope.
 
Ahhh
I see so its not the unit that BD sells.
Raywood was telling me about the units that are made for the Indian will work on the BD but you have to go through this to adapt it.

It's the same one, it's from BDM. You have to take the Tank off to run the line

My instructions for the medallion came from bdm and i had to take the tank off to run the new power.it's Pretty straight forward
Can you help me. I ran the line as in the instructions and the Speedo doesn't work correctly. The Left flasher works but not the right. If I hit the HI beam the right flasher comes on. And when I start the bike the Digital Display goes dead.

Has your bike had the PDM installed? I know when we put Raywoods in the new harness had an extra 4 pin connector specifically for the medallion. Might ask if anyone has the schematic for the PDM or do a search and see if someone has posted it on here.

No PDM, and I replaced the 3 PIN connector with the 4 PIN connector the Speedo comes with. Everything on the bike was working fine before replacing the Speedo. Everything on the bike still works fine, all lights, starts and runs fine, all switches work, everything but the new speedo is working.

I replaced mine with a Medallion last year. Installed the 4 pin connector. If i recall two wires have to be cut back and not used. One wire (black comes with kit) runs from the circuit breaker through the backbone and direct to the speedo. Plug in and everything worked.

Yes that is correct and what I did to install the Speedo. Cut both the Black and Red folded back and taped and put a plastic tie on it too. I put the Green in slut 3 as pictured in the instructions. I ran the included power cord thru the bike back bone and to the plus side of the battery. Everything on the bike was working fine before installing this Speedo. And everything is still working but the Speedo. My feeling is I either have a bad unit, or some wires on the Speedo are crossed. I say this because what the instructions have me hook up appears to ONLY be power to the unit. Everything else is already wired. And if there's a short in the power cord I ran it should blow the fuse. This is really pissing me off because I can't go back to my old unit that easy because I had to break the 3 PIN connector to replace it with the 4 PIN connector that the new unit came with.

If everything is hooked up according to the instructions, it is possible you have a faulty unit. I can't remember but can the unit be bench tested?

Not sure, but going to be returning it to where I got it from and hopefully they can replace it. Hopping they could plug it into another bike that has one already, or plug another one into my bike and see if it does the same thing.

Are you sure nothing unhooked when you stuck the speedo into the housing?
Checked that out and have the housing open now to try everything. I disconnected and reconnected everything I could and still NO GOOD. Speedo gets power but doesn't function correctly.

OK looking closely with both speedo in front of me this is what I found and I feel is in question. When looking from the back of the 8 pin connector with the locking tab on top I have the following colored wires in this order:

Old Speedo going from top left to right

1. Green 2. Purple 3. Orange 4. Black
5. Yellow 6. Gray 7. Blue 8. Red

On new Medallion Speedo from top left to right

1. Green 2. Purple 3. Orange 4. Black
5. Red 6. Blue 7. Brown 8. Yellow

Something doesn’t appear to be right here. If you have a Medallion Speedo can you please look at the 8 pin connector and see if your wires are set the same. If slut 5 on the old speedo is yellow shouldn’t slut 5 on the Medallion also be yellow????? Same on slut 8 which is red on the old speedo and yellow on the Medallion. The blue are mixed up to and the old speedo has a gray instead of a brown.

It appears that maybe the Medallion wiring harness maybe miss wired.

ANY HELP IS WELCOMED PLEASE

According to the PDM wiring diagram that i got for a 2007 K9 carb, the color combination that you have for the Medallion speedo is correct.

Not sure if it matters or not, but the instructions tell you to hook up the constant power wire to the circuit breaker, not direct to the battery.

Well the instructions did say either/or, and the unit is getting power. It's the other stuff that's not working right.
