TCI-Bench testing available

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, 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..............

Well I tried again but I can't seem to get the picture posted. Must be unlucky Thursday.

Here goes again

Maybe too big, possibly need to reduce it with freebirds picture utility.........

I see the picture ,nice unit

I like this idea. I might send mine up to see where it stands.

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.

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?

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.

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

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.

Take care

Hello i need my TCI tested can you send your address or phone number where Ican send it

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

Don passed away a couple of years ago.

His equipment was sold and not avalible.
