Acwell Speedo Tacho Installation

[BrettS]

Cheers Errol, All academic now because I no longer have the small tank but if I still had the small tank I reckon it could be worth a try to shorten the rod a bit. Might not work pefect but could be better than a warning light. Guess Yamaha had good reason to leave it out, just thinking aloud.

Cheers Eddy, that would be great. I will send you a PM.

Bretts,

I got one of them floating DooHickeys on a spare tank.  I'll get that to you somehowz.

Unfortunately, they won't work properly as there's not enough room for the float to move through its range of movement.

[BrettS]

So it seems you can put a small tank sender in a big tank. What happens if you put a large tank sender in a small tank?

[Eveready1100]

Yes, Brett. That's a thermistor out of the small tanks. They're simply an on / off switch.

This is what the sender unit from the bigg'uns looks like -

[BrettS]

Are you sure? That's what I thought at first glance but then I saw several the same for sale on eBay.

I would guess that it is from a smaller tank and they are actually interchangeable but I will leave the confirmation of that to the XS Guru's ??

Hey Brett half your fuel gauge sensor is missing. It should have an arm and a float on it like a dunny cistern. The level float arm is attached to a an electrical do hickey also in the tank on that plate you showed

[BrettS]

Well Speedo number three now hooked up and operational. All seems ok. I thought I was going to be able to hook up the fuel gauge as well this time but couldn't get it to work, always reads empty same issue Bryan had with his. I pulled the fuel sensor out of the tank expecting to be able to move the sensor up and down to see if I could get the reading to change and found this ??

Which I am guessing is the sensor which just tells you when you are out of fuel not a level? I thought they were only in the small tanks?

Also I reckon I may have found why my last speedo failed. When I went to change something on the speedo while riding I found the speedo had a small but strong vibration to it. Although the unit is meant to be strong and I have it mounted on the original rubber mount that the old speedo was on maybe the fabricated stainless mount is doing a bit of mechanical resonance ?
Makes a lot of sense so I think I will do a little redesign of the mount to ensure a longer life.

Oh and Bryan I found the readings for the fuel sender
Full = 6 to 10 Ohms
Half = 28.5 to 36.5 Ohms
Empty = 75 to 85 Ohms

That means the closest reading is 100r although it may never show empty, not sure. Also if you are not using the fuel gauge and the empty flashing is annoying you should be able to turn the fuel gauge off altogether in the settings.

Another thing that happened on the Run to Bourke was the speedo started playing up, The needle was rubbing on the backing display and it got a bit quirky on the reading.
Sent back for another replacement. So speedo number three turned up on the door step today.
I had hard wired the last one into the bike removing the bulky conectors so it will take some work to work out what goes here again

Great news Bretto...

[BrettS]

Got the replacement Acwell speedo on Friday. I even chased the postman down the road to make sure I got it Ha Ha.

Plugged it into the existing wiring I did with the last one and went for a run. Perfect. The revs seem spot on and are constant and reliable. the shift light comes on at the correct time every time. The Kmh also seems to be right. That works off the wheel diameter and is adjustable so may still need a slight tweak if my calculation was out.
Cost me an extra $20 in postage to have it replaced but I guess that's the way it goes some times. The seller was always very helpful.
Might have to do a little video when I get my head around all the functions. Got average speed top speed and revs but they are the simple ones.

Thanks Bryan, once I am comfortable all is well I will be going through the wiring seeing what is now redundent, there seems to be a few.

Sounds good ... I spoke to a couple of 12v sparkies (mates) who suggested that unwrapping the loom
a bit to make the connections was the way to go - I found that it was straight forward to connect it up -
My tacho is connected to a coil direct not a plug lead - the fuel gauge will work if I fit the correct resistor
or re-calibrate the sender in the tank - frankly, its not worth the trouble I reckon.

Thanks Bryan, The problem I have is not slight but at first probably double the rpm. When i connected to the coil it seemed to work Great and "seemed" to me to read exactly as it should but then after a good hard run the needle rpm would start to drop off and at times refuse to go over 2000 even though the bike was obviously doing around the 5000. Did you wrap your rpm wire around the plug lead or direct to a + coil wire.

This unit had several slight manufacturer faults visible. Just little things like what looked like glue on the very edge of the display, the cable had prominent drag marks were it had been pulled through the case when made, A few very small but definite scratches heading away from the buttons on the glass and little bits of fluff inside the glass. It just seemed that it was put together by a less experienced worker and maybe should not have passed QC.
I probably would have put up with all that but then we noticed the display moved on the left when pushing buttons and the RPM started going haywire showing a big difference (several thousand RPM) between the needle and digital display I started to think it had to be a faulty unit. The only possible thing I can think of that would do that is a bad earth and since I had earthed the unit directly to the battery with a strong wire I new that could be ruled out.
Talking with the distributor they agree and have asked for the unit to be sent back and they will "Likely" send a replacement unit. They seem like a decent supplier so fingers crossed that will go well. I have left all the wiring intact and just unplugged the unit to post away so it will be interesting to plug a replacement unit in and see.

How often is rarely though?  Bryan

Keep at it Brett  you, 'll sort it

[AussiXS11G]

hello Brett
when I fitted my Acewell unit I had issues with the speedo which were sorted by emailing George from Acewell
george <george@acewell-meter.com>
I suspect my unit (ACE-3853) reads high in the RPM but do not have a reliable tacho to verify this - its academic really though,
I rarely rev the poor thing anywhere near exploding....
