Why doesn't my cyclocomputer work?

What make and model?

I'm just going to hazard a guess that it's a VDO C1DS.

Live simply so that others may simply live

One thing that threw me off with my last cyclocomputer installation was
that the magnet and pickup were not supposed to be centered on each
other, as I assumed.

Finally, reading the directions, I saw that there was a tiny mark on
the sensor showing where the magnet should intercept the plane, and
once I moved it there, it all worked fine.

In the meantime, of course, I had redone and rechecked everything else.

Ahh! Directions?

I got a cyclocomputer for christmas and I can't seem to get it to read
properly. Specifically, it is a VDO C1DS. I have shecked the sensor
distance and alighnment, as well as the batteries, the required
information for accurate measurement, and it still won't read.

....

Make sure it's seated in its little holder thingie. Recurring problem
with mine.

That is why I don't hang out in .tech. Nearly everything on my bike is a

Happy Hollidays, Claire!

A thingie???
How about a gizzmo?
or a festerus for which you need a festemus to make it work!

Maybe some fancy, high-end mountan bikes have gizmos. *My* bike has
thingies, doohickies, and dealie-bobs (or as they are known in French,
dealies-pendillez).

Only the dura-ace doohickies are really expensive. An ultegra doohickie
isn't going to set you back that much.

Won't read properly, or won't read at all?
Assuming it's "at all", try
(1) cleaning the contacts in the harness/computer interface (e.g. with a q
tip and rubbing alcohol)
(2) putting the magnet and the pickup so close to each other that they bang
a bit, and seeing if you get a reading. If you do, then back off a bit. The
most common problem I have is the magnet and the pickup getting too much of
a gap.

^^^^^^^^^^^^^^^^
Lets approach the problem systematically. Since you were able to set the
wheel size calibration, I assume the unit turns on and displays properly.
Does it show 0 MPH while you are riding? This could be caused by a number
of things, and it is possible to narrow it down, rather than just try things
and hope something works. Take the cyclometer unit off the bike and try
"shorting" the contacts which go to the sending unit. You can do this with
a short jumper wire. If you tap--tap--tap at a rate that is in the range of
wheel rotation, you should see a speed displayed. If you don't, you have a
bad unit--the fix is to take it back to the dealer.

If that works OK, the next test would be to put an ohm-meter across the
leads coming from the sending end. Now move a small magnet across the
sensor--back and forth in various ways. The meter should respond to this.
If it does not, you may have a broken wire or a bad sending unit. This also
means a trip back to the dealer.

If both these tests are positive, then you need to make sure the wheel
magnet is activating the switch. Put your ohm meter across the contacts,
and spin the wheel. Keep moving the magnet/sensor positions until it starts
to work.

Finally, install the cyclometer in its bracket (thingy), and it should start
to work. If it does not, try wiggling it, or pressing it in more firmly.
If you still can't get it to work--back to the store. I have encountered
units that did not work, or did not work reliably, and the dealer
(Performance) cheerfully exchanged them for me.

All of this is based on the assumption that we are talking about a wired
unit. If it's wireless, the problem should be approached in the same way,
only you now have two electronic devices that could be bad--I would just go
back to the store with it.

Just in case you need the manual or manufactuers site

Can someone help, or at least direct me to a place that can? Thanks!

Don't know if you got the problem solved yet, but you need to follow the
instructions on the sequence shown in the manual for 'booting up' the
sender unit and the receiver.

You can try doing the link reset if it's anything like the C3DS.

Also, I was surprised to find the VDO magnets seemed to be MUCH weaker than
those I'm used to for magnetic pickups. You might need to get the sensor
and magnet a LOT closer than you're used to.

Anybody have any idea if there is any ill effect from using a non-VDO
magnet with a VDO sensor? I'd hate to try using a stronger magnet and then
find out I've zapped all the electronics in the sender unit in the process.
