davidbek95 Posted February 10, 2014 Report Share Posted February 10, 2014 I have wired up a gt101 sensor to read speed,wired into D1,as ground speed,i enble it,made it active,but no speed at all,i wired it up as it said to,i have tried another sensor.still no change.Any ideas. regards david Quote Link to comment Share on other sites More sharing options...
davidbek95 Posted February 10, 2014 Author Report Share Posted February 10, 2014 forgot to add in I have got a collar on the yoke.with 2 bolts,which adjusted 1.6mm of gap between the bolt head and sensor.no frequency at all regards david Quote Link to comment Share on other sites More sharing options...
bsh Posted February 10, 2014 Report Share Posted February 10, 2014 Have you scoped/checked with a diodetestlamp that the sensor actually reads the collars? Have you tried with pull-up on/off? I have seen people made trigger wheels of non-magnetic material resulting that the sensor doesnt see the teeths... Quote Link to comment Share on other sites More sharing options...
davidbek95 Posted February 10, 2014 Author Report Share Posted February 10, 2014 these bolts are not magnetised,could this be problem.the collar is alloy,but bolts aren't magnetised but made of steel.i have no testing quipment,other than a multimeter. regards david Quote Link to comment Share on other sites More sharing options...
Dave Kriedeman Posted February 10, 2014 Report Share Posted February 10, 2014 Hi, The GT101 sensor is Hall Effect and does not require a magnetic tooth or trigger edge. the GT101 sensor really needs to see a clean tooth edge. The GT101 is a hall effect sensor that is normally used in conjunction with a trigger wheel or tone wheel. If you are using bolts in your collar, how far is the sensor end to the collar. If the distance to the collar is to far the sensor may not be able to trigger correctly, remember that the collar surface will be regarded by the ecu as the 0 volt negative face, for the falling trigger edge for the sensor I normally run with an air gap of .040 / 1mm to the top of the tooth, with GT 101 sensors. You really need to have a nice square tooth for the GT101 to get a clean trigger edge. Are you using 8 volt or 12 volt to the positive of the GT101. Regards Dave.

davidbek95 Posted February 11, 2014 Author Report Share Posted February 11, 2014 David, have check the distances out, also I am using 8volts.As specified in the manual. regards david Quote Link to comment Share on other sites More sharing options...
Dave Kriedeman Posted February 11, 2014 Report Share Posted February 11, 2014 Hi, can you post a picture of the sensor setup with your trigger tooth setup/collar. I also agree with Ben, that the alloy collar would not work as the Hall Effect sensor would not be influenced by the alloy but would be influenced with the bolt. Regards Dave.

bsh Posted February 11, 2014 Report Share Posted February 11, 2014 You must confirm that the sensor outputs a signal when it sees the tooth. If it doesnt, the ViPEC will never see the signal and you will therefore not get any speed measurements. You should buy/borrow a diode test lamp (they are really cheap) and see that the output signal change when the tooth passes by the sensor. I believe it should work if the tooth is made of a material that will work with the sensor. Not stainless steel or aluminium. You can use a cheap diode test lamp as this one: http://biltema.no/no/Bil---MC/Verktoy-o ... 8-V-15669/ Cost about 5 usd. Quote Link to comment Share on other sites More sharing options...
davidbek95 Posted February 11, 2014 Author Report Share Posted February 11, 2014 Ben, I have seen those diode testers, I will go buy one tomorrow.thanks Ben Quote Link to comment Share on other sites More sharing options...
davidbek95 Posted February 12, 2014 Author Report Share Posted February 12, 2014 well worked out the problem, its in the wiring, I have to check tomorrow, as I ran another set of wires from the ecu to the gt 101 sensor, and it worked, so the problem in the wiring, I used the proper cable wire, I used deutz plugs as well, as soon as I put steel nnear the sensor, I seen a reading, which I am happy, so got to nut out the problem. regards david Quote Link to comment Share on other sites More sharing options...
davidbek95 Posted February 13, 2014 Author Report Share Posted February 13, 2014 Ben and David, Well good news,, I found the problem, when I crimped the deutz plug pin, as there was no contunity, from pin to ecu, I do not know, replaced pin all good now, just got to go calibrate now. thanks guys for your input.
