cdi resistance measurements
Hi All,
Has anyone performed resistance measurements on a CDI unit (A4's and
higher included) per the table in the KLR650 supplement? I just did,
and am getting about two thirds of the values in the table to fall
within limits. The other third having to do with the white or red
wires are coming out way on the high side. I'm talking meg-ohms
instead of kilo-ohms.
Would you have a good CDI unit that you could measure the resistance
of with respect to the red and white wires? If the table is to be
believed, then I have a partially bad CDI unit. I thought it was the
starter lockout switch on the clutch lever, but it aint. I've been
over that sucker and now believe the problem is the CDI unit.
Thanks for any help.

cdi resistance measurements
For some reason, the white and the red wires will only read correctly with
an analogue meter. I found two different results with digital meters, one
was reading infinity, the other was into the mega-ohms. I wrote down the
values from stock - if I have a problem and want to check it, at least I
have a baseline to see if something has changed. FWIW all other
measurements were in spec.

cdi resistance measurements
Hello Bruce,
If I understand you correctly, you are getting some very high readings, (in
the megohm range) when you attach the positive lead of the ohmeter to the
red wire and the negative lead to the white wire. This is good if you are
getting a low reading ( 10-55 ohms)with the positive lead of the ohmeter
attached to white wire and the negative lead attached to the red wire. This
indicates that the diode junction in that part of the circuit is
functioning properly. If you had two high readings (megohms) with the leads
attached either way, then you would have an open circuit indicating the
diode is not functioning properly. This would be a rare occurrence, not
impossible, as the failure mode of a diode junction is usually to short
out and give you a low reading both ways.
Follow this pattern for all the connections and you might find that you
have the proper indicated readings. ( Note I did not say you had a good
unit, just that the ohmeter checks are not finding anything abnormal)
The high readings are not to worry. the infinity sign tells you better is
higher.
Hope this helps
Marcel

cdi resistance measurements
Some digital meters do not put out enough voltage to overcome the diode
avalanche resistance. That is about .7 volts and double that if two diodes
are in series. Sometimes when making circuit measurements that is an
advantage. The better meters have a diode setting which increases the
voltage out. This is the diode scale. Most analog meters simply put out
more voltage than necessary and thus check diodes very nicely. I would
recommend a simple analog meter for the diode measurements in the CDI unit.

cdi resistance measurements
Bruce,
Enclosed are my A9 CDI test results using an ANALOG VOM. Check out message
#8095 at the KLR Yahoo web site for additional info on CDI testing. You may
want to download & print my KLR color wiring diagram from the FILES section
at the yahoo site (in the WIRING AND INSTRUMENTS folder).
You can electrically disable all the safety switches by:
1) connecting the RED/BLACK CDI wire directly to ground
2) connecting the BLUE/RED wire from the STARTER
CIRCUIT RELAY (or the clutch switch) to ground
You could make this into a permanent ON/OFF safety-disable switch by using a
DPST switch. This would allow you to keep all the safety interlock
features, but disable them with a flick of the switch at any time.
Let me know if you have any further questions.

This is the stuff that seems to go uncommented on...I'm in awe professor...next KLR
I'm getting I'm using this approach...thanks.

OK, I'm going to start another list for the shopping cart. The reason is
that not everyone will be interested in what I have in mind and I want to
encourage careful discussion about what we're doing. I've already put
together one cart and I was very satisfied with what I came out with...this
one has to be the ultimate but not just what we might throw at it. So, over
on this list we can debate in good style whether to go with a suspension mod
or not...where to store the cans and bottles....what kind of brakes...etc.
See you on the other side...

I'm not a moderator but I play one on this list...

Rich, this sounds really good...but I'm having trouble subbing...maybe you can
help...
Thanks,
