VDO Speedometer

Know this has probably been covered but getting no where . . .

Have an 89 110 that just put a 200tdi/R380 and has LT230. Have the YBE 100530 connector. Believe the outer 2 go to pins 7 and 8, but not registering anything. It does come on, lights up, just shows 0, when I tried to set it an "L" came up but after I hit it after going 1 mile still at zero. Gage needle never moved . . . Thoughts?

I still need to program mine so am interested in figuring out how exactly these work with a VDO Speedo.

Are you sure you have the YBE100530? Green with 3 pins and I believe it has a Hall Effect sensor built into it.

The YBE100430 has 2 pins and Variable Reluctance (VR).

I have to recheck my wiring but I used Tom's posts as a guide: http://www.defendersource.com/forum/...r-26385-3.html

Rereading Tom's and John's posts I now know I wired my incorrectly and will have to revisit. (Makes sense why it didn't want to program when I tried).

Curious as what the plug from the YBE100530 to VDO wiring scheme should be.

Hell, now that you mention it I'm not sure . . . Galpin brought it over and installed it as mine didn't ship in time. Will have to take a look when I get home.

Per the posts linked above.

VDO pin 2 (regulated +12V) connect to YBE100530 pin 1
VDO pin 3 (ground) connect to YBE100530 pin 2 and ground.
VDO pin 8 (sensor signal) connect to YBE100530 pin 3

I also believe this type of hall effect (open collector output) needs to bridge VDO pin 6 to VDO pin 8.

if it were a YBE100540, what would be the difference in wiring?

The two leads connect to VDO pins 7 and 8 if it is being used by itself. If including an EFI ECU in the circuit is is different and explained somewhere else around here....

Thanks John - the 12V piece has me confused. I checked the VDO speedo this morning and Pin 2 does not have any power (gauge powers up power to Pin 4) according to my test light. Should I split a 12V source to power Pin 2 and to Pin 1 on the YBE100530?

Any help would be very appreciated. Thanks

copy, no ECU, just fat fingers that have no clue what they are doing . . . too many wires . . .

Pin 2 on the gauge should output power when the gauge is powered up. Pin 4 is the input power. You could just run straight switched power to the sensor pin 1 and not connect anything to pin 2 of the gauge.

Thanks - I will do some more testing and see what is going on. Like you said I could just run power straight to the transfer case sender.

Here is the wiring for YBE100540 with the vss feed to the ECU (such as for NAS 1994). The resistor is a 120 ohm. http://www.defendersource.com/forum/...2&d=1389196177

And for the YBE100530, I believe Johns post is correct. On VDO, Switched power to pin 4, pin 2 power out to ybe power in, ground to pin 3 and ybe ground, and the signal wire from ybe jumped to pins 6 and 8. Here is a diagram, your wire colors may vary. http://www.defendersource.com/forum/...8&d=1339329614

I have a ybe100540 sitting in a box along with my VDO. I haven't installed it yet so the above is all the information from reading all the posts about it. I have every reason to believe they are correct as they are the latest consensus and no one chimed in further after these wiring methods came out. Still, it is Theory until mine is up and running so I hope it is correct :-)

Thanks Davis - still puzzled why I wasn't getting power out of Pin 2 on the VDO. Going to pull it out of the dash and test on the bench.

John, finally have this sorted . . . all info above is correct, had 2 wires switched . . . found this site for testing VDO gauges

http://www.bugsandbuggies.com/pdf/vdo/0-515-012-178.pdf

Wiring of Sender to Speedo:
Red on sender to term #2 on speedo
Black on sender to term #3 and ground
Off-white on sender to term #6 and #8
Switched 12v to term #4
Testing Hall Effect Sender:
Turn ignition key .ON.. Put red lead of voltmeter to term #2 and black lead to
term #3. You should have between 5-12volts dc.
With the key .ON., leave the black lead on term #3 and put the red lead on term
#8. Remove the sender from the transmission. Rotate the square drive shaft in
the sender very slowly with your fingers. You should see the voltmeter pulse
from 0-4 volts dc. (0-4-0-4-0)
If it pulses, the sender is working properly. If the voltmeter stays a constant 5
volts dc, the sender is defective.
--------------------------------------------------

There is more info for other VDO gauges on the link . . .

Appreciate the help!!

Mike
