DonB Posted November 8, 2007 #1 Posted November 8, 2007 Well I have finally finished my Bench Tester for TCI's. I can now take in anyone's TCI to test and give a report on the results. The test will consist of the following. 1. Test each input coil circuit to see that it activates the corresponding ignition coil output transistor in the TCI. 2. Test the circuit for the kickstand switch ensuring that it deactivates the TCI. 3. Test the circuit for the pressure switch making sure that it advances/retards the timing. 4. Test to see that each ignition coil is getting the proper voltage to energize. 5. Run tests at a simulated 900 RPM up to 6000 RPM at various speeds. I can bench test the TCI without taking it apart by unsoldering the motherboard from the case. I can also test the board even if it has been taken out of the case. I will do this testing for $30 (return postage extra). Any repairs would require taking out the board and replacing components as required. Pricing will depend on what components would be required but total cost above the $30 should be under $75 (postage extra) I just completed a repair for Rich at wera90ex@aol.com and he was quite happy with the results. (He said I could use his name as a reference.) I'm attaching a picture of my test rig which outputs to my scope. The picture shows an output from a good TCI running at about 1000 RPM. It shows a test for input coil #1 with the output going to ignition coil #1. It was very hard to get a good picture but this does show the output. Any queries about this testing can be sent to me at donb@MNSi.net Best regards to all Don Brechun Windsor, ON
Rocket Posted November 8, 2007 #2 Posted November 8, 2007 Well I have finally finished my Bench Tester for TCI's. I can now take in anyone's TCI to test and give a report on the results. Don, is this limited to Venture TCI units, or can I have a '82 XJ750 Maxim TCI unit tested? BTW the picture is still not showing..............
DonB Posted November 9, 2007 Author #3 Posted November 9, 2007 Well I tried again but I can't seem to get the picture posted. Must be unlucky Thursday. Here goes again DonB
Rocket Posted November 9, 2007 #4 Posted November 9, 2007 Well I tried again but I can't seem to get the picture posted. Must be unlucky Thursday. DonB Maybe too big, possibly need to reduce it with freebirds picture utility.........
CrazyHorse Posted November 9, 2007 #6 Posted November 9, 2007 I like this idea. I might send mine up to see where it stands.
DonB Posted November 9, 2007 Author #7 Posted November 9, 2007 Rocket The Bench Tester was made specifally for 1200/1300 1983 to 1993 units but I'm sure that yours would be quite similar. I could prbably jury rig the tester once I have a look at yours and figure out the pinouts. If you have an electrical schematic of your bike that would help. I would be willing to take a look at it.

pegscraper Posted November 9, 2007 #8 Posted November 9, 2007 That's a real nice looking cabinet. How did you do the lettering? Can you determine how many degrees from TDC the spark is advanced with this?

DonB Ok, will pull it off the other bike, when I get home for Xmas leave, next month. I also have a manual with the schematic.
DonB Posted November 9, 2007 Author #10 Posted November 9, 2007 Pegscraper I did the faceplate layout on Autocad then printed it out onto stickyback paper then stuck it on the front of my project box. I could probably work out where it's firing from TDC by the scope trace. The trace shifts when I do the pressure sensor testing. If you look closely at the trace you can see that the coil is powered up to about 13 volts and when the input coil sends a trigger signal the power to the coil collapses and that's what produces a 13,000 volt pulse to the spark plug. The vertical scale is set at 5 volts/div and the horizontal is set at 10ms/div so from that you should be able to calculate what you are looking for. That trace was done at a simulated 1000 rpm. Hope this helps DonB
DonB Posted November 9, 2007 Author #11 Posted November 9, 2007 Rocket Hey, didn't realize you were in the forces. My stepdaughter was until recently with the Air Force and she was in charge of the mechanics who took care of the Snowbird's planes at Moose Jaw. She's doing training in Ottawa now after she left the Air Force. Small world Take care DonB
wrs6845 Posted March 22, 2012 #12 Posted March 22, 2012 Hello i need my TCI tested can you send your address or phone number where Ican send it
Trader Posted March 22, 2012 #13 Posted March 22, 2012 This thread is 5 years old and the OP has expired membership....probably not around anymore. He hasn't been on the site since 2009
dingy Posted March 22, 2012 #14 Posted March 22, 2012 Hello i need my TCI tested can you send your address or phone number where Ican send it Don passed away a couple of years ago. His equipment was sold and not avalible. Gary
