Hello, New to the forum, and hopefully would be able to get info from someone on here about, the COMBO ANALOG SPEEDO/TACH 70900070A. I have a 2008 fatbob and want to put this gauge setup on my bike but can't find any info on this and if can be done. From what i cant tell the new part#70900070A was added to fit the old bikes. But every Dealer that i call has no clue as to what im talking about. Has anyone installed this gauge setup on a 08 Fatbob?? Thanks

Jay

 

Can't help with that part #, but there is thread here somewhere about part #70900274 which may help explain dealers lack of knowledge. Good luck.

 

Yep I put one on several months ago, no problems.

 

Not sure it it's the exact same part number, but I have that exact style on my 2010 Fatbob. No problems.

 

Should work:

Fits '04-'11 Dyna®, '04-'10 Softail® (except FLSTSE) and '04-later Road King® models (except FLHRSE3/4) equipped with a 5" Speedometer.

I installed the same one on my '06 FXDi35 a few months ago. Love it. Easy to install, just make sure you follow instructions to set your mileage.

 

Just installed on my '04 carbed FXST. Easy to install, plugs into data port with supplied cable, turn on ignition, wait for it to copy from original speedo and then install. Be Aware, original Speedo is required to complete data transfer, I had already pulled out old one and tried to do the data transfer which failed miserably. On another note, speedo/tach works awesome, only functions that don't work are gear indicator and fuel range left. fuel gauge seems to be pretty accurate.

 

What I found was the A for for MPH/KPH, and the B ending is for a speedo with only MPH.

 

Weird thing, I have an 05 road king, and speedo shorted out after washing it. I bought this same tach, but the model # ends with B instead of A. Same thing except for there is no KPH on MPH. I followed the install and data link to a T, and when I would ignition I'd get a NO CAL in the LCD, and then that would go away, and it was replaced with NO SPD. It would not transfer the odometer to the new odometer. I'm thinking that if your speedo stopped working, replacing it with this type of Speedo will not work due to the inability to transfer odometer reading of a broken speedo to the new speedometer. I can't find anyone with an answer to this.

I thought this might be an issue, as the old speedo was as if it wasn't there because IT WAS BROKEN (insert Sam Kinison Tirade). Our shop service guy in Folsom checked with the mechanic, and "it's okay, just follow the directions." Engine switch on, Data Link plugged in, no go! I had the old speedo out, and was tapping it and banging it slightly, and I saw LED partially show numbers, they would immediately dim if I stopped squeezing the old gauge. Thinking the ecm possibly sensed the old speedo after doing the Fonz bang and tap on the old speedo, which seemed to allow some juice into it, so I did the transfer procedure again, and something did change this time as it just went to NO CAL, without going to NO SPD.

I'm assuming NO SPD means it isn't sensing a speedo. Well It stopped that, and the NO CAL shows. There is a red light blinking, but then after a bit the red light goes solid and stays on. But still it did not do the conversion. The trouble shooting guide for this particular NO CAL says, normal function, but ads as long as "percentage and ok" show, which they don't. I went ahead and plugged the new speedo into the consul to see if something happened, and the new speedo lit up beautifully, but with NO CAL or something I forget. But no odometer transfer. I'm wondering if I should ride it and go through that 31 mph countdown the document spells out.

I'm going back down to get a speed sensor. Apparently, it could be that issue if the signal lights don't cancel, for one sign. With the bike just leaning on the stand, it doesn't cancel. Somebody said I had to at least lean it or move the steering for it to cancel, which I haven't done. So, I'll check for cancellation leaning and turning the bike. With all the forums out there only about 4 of these issues are on the net, and none of those who had the problem explained how they solved it. These speedo combo's don't work if your replacing a broken one. They should explain this, as there is no refund for them. They seem to only work if you are upgrading. I need to get the odometer reading back, as I'm selling. Any ideas?

 

I seem to have run in with this issue also on my 2012 Fat Bob. If I hold trip and flick to IGN instead of ACC It lights up all colours but then goes to only saying BCM - N. Speed -N and DIAG -N. Cant seem to workout how to get it into Setup mode. Was working fine for months and just leant I could change colours. Ive tried with key fob on me and away. In Run position and Off position also.. Any gurus have an answer as yet haha? Thanks guys

 

Well it appears I was sent to the wrong page.
If anyone else was misdeirected like myself I found the correct procedure
