    I was on their site before and they state that they do not sell to distributors or individuals. A search on their site indicates that they have all three chips. db

    Pegscraper Great stuff, I found 2 of the chips on the Mouser site. Now all I need is to find the HA1825P and I'mm all set. db

    Jimbob5 No the parts I need are for the 1983 to 1989 TCI. Pegscraper OK I'll give thos a shot. Thanks db

    I tried them this am and nothing comes up on their website. Thanks anyway. I'll keep on trying. db

    I am in the process of repairing another members TCI and after removing the timing chip daughterboards I find that I need the following chips Hitachi HA1825P 20 pin dip Nec C1251C 8 pin dip Hitachi HA 17902P 14 pin dip If anyone can point me in the right direction in finding a supplier for the above it would be greatly appreciated. Attached is a picture of the TCI with the daughterboards removed showing the above chips. TIA db

    attached is a partial copy of the XVZ12TK wiring diagram which clearly shows 4 input coils just to the upper right hand side of the AC generator. Coil 1 is connected to black & orange wires Coil 2 is connected to orange & silver wires Coil 3 is connected to green/White & Orange wires Coil 4 is connected to Orange & Red/White wires As the generator spins past these coils in turn it then produces a trigger voltage which is sent in turn to the ignition coils 1,2,3 & 4 Anyway, that's the way I read the schematics db

    I hooked up my 2 meter radio as shown in the attached picture. No vibration or anything to worry about. I did find though that I can't transmit with 50 watts as it drains the battery too much. I just leave it set to 5 watts. db

    Here's a pictorial of the TCI pinouts which will help to explain how it works. Each output ignition coil is activated by a corresponding input coil. I have built a bench tester for TCI's 1983 to 1993 if anyone is interested. I don't have to take them apart for testing as I just hook them up to my tester. Here's a couple of pics to help. db

    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

    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

    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.

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

    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

    I really must apologize for the 1st pinout drawing that I provided as I was checking out the pinouts today and when I compared them to an opened TCI I found that some of the pins didn't match the colorized electrical schematic I have. Some of the coil numbers were incorrect so I have taken them off the pinout drawing until I have a chance to trace them on my bike which is a 1985 1st Gen 1200. You can all shoot me later. Regards DonB PS if anyone wants a larger version then email me at donb@mnsi.net

    Jeff Yes those are the plugs I need. My address is: Donald Brechun 850 Lynn St. Windsor, ON Canada N9G 1G8 ============================ The cowl wouldn't fit correctly the way I had it bolted down so I cut off the mounting lugs, put some velcro on the underside (smooth side)and pushed the TCI as far forward toward the batter as it would go and it fit OK.

    Jeff Here are 2 pictures of the 1stGen TCI plugs I am looking for. TIA DonB

    Hello all Well I've been working on making a bench tester for the 1st Gen TCI's and I could use the cables/plugs that go to the TCI. Has anyone parted out a 1st Gen bike where I could get these cables? It would simplify hooking up a TCI if I had these. DonB I can be reached at donb@mnsi.net TIA

    Laxman Make sure you are checking across the correct pins because it sounds as if you are reading across 2 coils to give you double the resistance reading. As an example, if you test across the White/Red stripe and the Black wires you will be reading across 2 coils and also if you take a reading across White/Red stripe and White/Green stripe you also get 220 ohms. You'll also get 220 ohms across the Black and Gray wiring pins. Now the color coding I give is for a XVZ12TK Venture and I'm not sure what bike you have but be careful where you take the readings. Hope this helps. Regards db

    OK, I dug out the information from the electrical schematic for the XVZ12TK. All the info is there it's just a matter of following the wiring and then testing it out on the bike. Freebird. I can send you the bigger file if it will help in looking at it. Reason I say this is cuz when I look at the picture I sent in it doesn't show up too well. Regards db

    Hi I've compiled some information which may be usefull for anyone who is having problems with their 1st gen venture This will help you to check out the Ignition coils and pickup coils without digging them out to confirm they are within specs. Feedback is welcome (good or bad) DonB http://www.venturerider.org/images/tci.jpg

    John Have you checked the fluid level in the battery? DonB

    Harbor Freight has a good deal on a box of Metric and/or regular O-rings with many sizes for around $10 and sometimes goes on special for around $6.

    TJF You have to unsolder the 14 connections on the board that attach to the two plugs. There are 8 connections on the left and 6 connectors on the right when you are lookning down onto the board. Then remove the 4 corner screws and the center screw. I use a solder sucker when doing this and then check that all the connections are loose. Be careful that you don't destroy a copper trace or you will then be doing a trace repair. I will be checking the spare TCI later on tonite and I'll let you know how it looks. db

    Daniel Well if you want to send it to me I can look at it and if it's repairable I would then make it available to any member who might need it. Only this time I would send it to members only!! db
