electronic speedometers?

[mr rip]

I'm just finishing off a project bike & it's all going well apart from the fact that neither of the wheels has a speedo drive as the drive came off the front sprocket & seeing as I've put a different engine in it I now have no speedo drive at all

I've been doing some searching & managed to find Trailtech & Acewell speedo's but all their models seem to run on 12v & my bike runs on 6v so no joy there

I've sent emails but had no replies as of yet, so does anyone know of any company selling ones that will run off 6v electrics?

any leads or links would be appreciated

thanks

the trail tech ones you can get to run off an internal battery,
failing that the sigma push bike speedos do the job and go to 199mph

thank's hmmmnz,

the trailtech battery only runs the memory, from what I can see on their web site, but I'm still waiting to hear back from them. Also, all their kits are model specific making it hard to figure out what bits I actually need for this contraption of mine

the acewell ace-1500 says it will run off an internal battery, but, yet again, no one is getting back to me to say what other parts I need

I've got a cycle computer on there at the moment (2 actually) but the ignition interferes with the signal, so when you rev it up the thing says you're moving even when you're not, they're not legal on a motorcycle anyway because the back-light only stays on for a few seconds at a time

thanks anyway

thanks truslack,

I had thought about putting a little pilot bulb above it to light it up but the interferance from the ignition was still making the thing unusable anyways, so I hadn't got round to it

but the 6v to 12v step up power converter is a realy good idea, I think some early cars ran on 6v so there might be some automotive equivalent out there

I guess I'm off to do some surfing, cheers

What current do the electronic speeds draw, any idea?

[mr rip]

not sure what current they draw & the info paiges are all a bit vauge, kind of along the lines of "look, its a speedo, add to basket" & not a lot else

as for the power converter, I've just found this one on citron classics website, It says it'll give enough power to run a sat nav or a lighter socket to charge a mobile phone

looks pretty small & neat, ideal for a bike, but not cheap at £52

I'll keep looking

Taken from Trailtech's website:

[truslack]

You should be able to make your own kit up from the spare parts page for a trailtech:

https://www.rpamx.co.uk/acatalog/Trail_Tech_Speedo_Spare_Parts.html

1 Vapor head unit £53
1 Air Cooled Temperature Sensor Vector or Vapor £23.01
1 Motorcycle Speed Sensor Cable Vector or Vapor Computer (I Presume this has the reed switch built in) £18
2 Vapor Power / Tacho Cable £10.02
1 Handlebar Mount for Vapor / Vector £10.02
1 Sensor Magnets (All Trailtech Computers) £4

Obviously you only need ALL this if you want temp sensing, tacho etc.

Hope this helps

Just connect up a square 9v battery, i've got a Trailtech Vapor, and in the manual it says, 9.0-400v AC/DC polarity independent, just connect up a 9v battery and keep a couple of spares in the seat.

[mr rip]

thank's for the tips guys

truslack where did you find that info on the trail tech website cause I couldn't find it , I must be blind,

I better go back & have a proper look eh?

I just saw it in the power lead discription, DOH,

it would have been easier if they said that in the main speedo description paige though

I still have the problem of all their senders & leads all being model specific, I could take a gamble & order one at random but you never know what your going to end up with

I am a few steps closer to knowing what I need though so I'll keep brousing

thanks

it's a 6v three phase DC generator & at top wack it only just get's up to 8v, & not realy understanding how it works I wouldn't know where to take a feed off it

I just went and checked with a 9v battery and a 6v pack i made up quickly and neither worked.

[mr rip]

[serlant]

yeah i mentioned that above, which is why i thought i'd give it a try.

[mr rip]

I obviously got bored reading all the diferent modles on the list on the trailtech website & gave up too soon cause right at the bottom of the list is a generic model for standard forks,

I'm hoping it's the one you need if you don't have a speedo drive cause I've just ordered it

at least it'll look like I've got a speedo on there untill I can get the power sorted out

https://www.trailtechproducts.co.uk/acatalog/75-200.jpg

I'll get out there tomorrow & check the genny output if it's no good it'll have to be a power converter

Just a point, my S4's speedo would flicker reset and generally crap out if the battery was low I can't imagine a 6v powered bike could keep a speedo running. My RXS couldn't even run my indicator and the brake light

How about emailing Trailtech, [email protected] ? I'm sure with the amount the sell they must have dealt with 6v before.

Maybe you can get someone to knock this up?

No idea what the current draw is but there are these sort of things for low power applications.
