The main function of a diode is to block the current in one direction, and allow current to flow in the other direction. Current flowing through the diode is called forward current. There are several types of diodes: Rectifier diodes -- these are the most common, with its function described above. Detector diodes -- these are more sensitive than normal rectifier diodes. They are used in radios and televisions to convert radio signals to audio or television signals. Zener diodes -- These diodes are the opposites of the normal diodes, because they are designed to conduct current in the backwards (reverse) direction BUT only at a very precise voltage. Zener diodes are used to regulate voltages (to behave sort-of like a battery). Capacitance diodes act as tunable capacitors and are also used in radios and TVs to allow electronic automatic tuning. Tunnel diodes are used in oscillator circuits HOLY CRAP ALL THOSE BANGS TO THE HEAD DIDNT HURT MY LONG TERM MEMORY LOL

But would need the board tester that Yamaha probably destroyed Sent from my Z812 using Tapatalk

That's if memory serves me correct from working at the coin ops Sent from my Z812 using Tapatalk

I haven't taken the TCI board out yet but is there capacitors on the board and should b 4 heat sinks in there one for each circuit and seems almost like diode problem Sent from my Z812 using Tapatalk

I'm getting -0.09 on coil connections with just the key on but if I remember right I got 12 volts going to TCI it's just not coming out that way I just measured resistance coming from plug it all measured in specs and switched the coils last night to see if I could get spark from no. 4 which I did get spark. It just wouldn't make sense 4 the coils to just die I may have confused some by asking the questions. Sent from my Z812 using Tapatalk

And do it with voltage and test the voltage Sent from my Z812 using Tapatalk

Now that is a Shovel Head but could have swore you could ride a shovel head you forgot the motor lol

But it's not something I will do with a good TCI I would prolly get knocked on my ass Sent from my Z812 using Tapatalk

Not no more I don't but I can now hold metal while I crank it and it tickles Sent from my Z812 using Tapatalk

Ok that makes sense as to y I got bit can't I just put points in the bike Sent from my Z812 using Tapatalk

Got a question what does yamaha do with there stuff when there done building a specific bike because if they have discontinued the tci boards would mean that they would have the testers to test them.....

O and by the way i used to work at Coin Ops and we put together boards and test them and sometimes they would have bad resisters so i took good resistor home and bad resister and took them apart... the wire went from what i remember all the way thru that stoney stuff and after tearing those resisters up i never did figure out what was wrong with the bad resister

Yeh I have taken these caps apart and cleaned them up and i knew not to mess with resister basically my question was if there was supposed to be very low voltage in the high tension wires with the key on i would say there was posibley 2 volts give or take. Ive already done all the other testing by reversing coils etc to see if there was spark and i know all 4 coil packs are good.. and all 4 high tensions are good just replaced spark plugs so she does try to turn over but the only thing i dont have anymore is the low voltage going to my high tension wires. I just never would have done that if i hadn't got bit while the bike was just in the on position. I just dont have papers with a certification and all the bikes i have ever owned were on the points system and the old way of testing spark well im too hold to hear hold this medal thing while i pull the chord lol... so I may be confused of what your saying because there again i see primary and secondary and if i have understood everything correctly I think what your telling me yes I should see low voltage in the high tension wire.... and the secondary is from the pick up coils and the one that actually sends the spark... correct me if im wrong.. I have problem when i try to explain things and sometimes sound a bit well cocky not try to but i am pretty much learning with the bikes because i have always had point systems and this electronic stuff on the bike is crazy i never did like it in the cars... but have learned to live with and learned to work on them and it seems it has made them easier to work on for the most part......

Alright I have a question for any of you who has ever been Bit while working on spark plugs wires while the key was in the on position... but noone hit the starter button. The question here is when Marie was up and running and I had to trim Back wire to get rid of some corrosion I was listening to my radio and had flipped the key too far anyways while i was using wire cutters to cut thru the spark plug wire i felt a little tingle.. So that gave me an idea to use a test light to check the rest of the wires i found another dead wire that way out of 4 i had 2 dead ones... all i did was simply used my test light put it in the cap and hooked other side to ground and had a dim light in the tester after i trimmed all the wires i then hit the starter to check them all and the light would go from dim to brighter when i would crank the bike. well it no longer does this and i can only check for a spark by sticking screwdriver in the cap and ground against body and i see weak sparks and one coil aint getting power at all which has basically left me to believe the TCI unit is bad.. However my question is just about that initial thing i discovered with low voltage going thru plug wires. so i have seen talk about Initial charge here and there and that pick up coils send the signal to tci to send fire charge to cylinders, so basically if i havent confused any of you at this time cause i am just curious if that is something i was supposed to see happen? the low voltage coming thru the wires when key was just in On Positions anyways thanks for all the help this far... by the way Marie was built in 83':think:

as a matter of fact i have thats what is in my carbs the float needle i believe is the wrong size for ours and that other piece i couldnt use either but i bought it for like 20 bux for all 4 carbs and mainly what i needed was all the gaskets... but if your gonna pull the carbs you might as well use everything you can and clean them out real good its what i did i didnt need the enrichers valve gasket but replaced it anyways

I would like to know where you found one so cheap lol

My neighbor had one and it felt good it just sat low but he couldn't figure out y it would only fire with hot battery I tried to explain to him he needed to replace the battery but he not the brightest crayon he let it go back cause of that single problem his battery would test at 11,2 volts but at 12.5 it would fire fine Sent from my Z812 using Tapatalk

But the thing is my wires aren't copper at least don't appear copper they are silver greyish color Sent from my Z812 using Tapatalk

Damn autocorrect Sent from my Z812 using Tapatalk

Thanks freebird that's the one I couldn't remember where I seen it Sent from my Z812 using Tapatalk

OK so question here im just bored watching Between well not bored watching it but anyways i decided to pull the two wire i wasnt getting fire from well i disambeled the wire and there is continuity in the actual wire itself which tested fine but as for the caps i cant get a continuity test on them it just keeps saying one and dont go to digits so it possible my caps are bad is there anything i can do to possibly fix them? regardless possible fix for this seems like it be cheap granted my tci board actually got cooked well enuff to fix that problem....

I already have the same one seen someone looking for it and tried the link and posted so it would be brought back to front to sort of say Sent from my Z812 using Tapatalk

Heck i kinda believe that Dan Cause i keep looking for a Venture Royal lol.... or another venture but been looking out for an actual Venture made trike dont know if they make them but heck if i could get one of those it would be awesome.. I dont like the way they want to convert my bike into a trike cause sorry I DONT NEED NO STINKING TRAINING WHEELS......

How big is this manual lol I have 100mbs connection and its taken 10 minutes so far to load lol

Im in SW Missouri and well it was 1.78 earlier today my gas is still at 2.90 but thats 91 octane NO ETHANOL premium E85 for my tahoe if i feel like 12 miles to a gallon is 1.59....
