tachometer wiring
 

i thought i could just wire the new tach with the wiring from the stock tach i get the damn thing to light up but it doesnt move... the new tach is not stock. any idea?

Not stock as in not made by Honda? or not stock as in modified? Or ?

not stock as in not made by honda.

Then you can either read the manual that came with it, or/and tell us which one it is, and it's possible we migth be able to help... But with the current amount of info my best advice is.... Eh.... Good luck!.... :rotf:

hmmmmm.... touche.

its a cheapo one i got online. the instructions are as follows

red wire to ignition
black wire to ground
green wire to coil
blue wire to "lamp on"

Dammit... I'm evil...;)

that masive amount of info was literally on a piece of paper the size of an index card. and like i said it lights up but the needle does nothing.

and yes your evil... now do you mad genius stuff an fix it.

Um... green wire to coil as in the signal for the coil then... Not really the tacho signal then... So if you have it wired at the plug up front, it probably won't work...

Not sure where you did wire it though, so I'm guessing...

Oh... I forgot... Muhahahahaha....;)

i pulled the guage cluster and wired the new tach off the leads that went to the old one as they were labeled off the back of the cluster assming the yell/grn wire which was the only unlabeld one was the said signal from the coil.... was that assumption wrong? if so where would i find the appropriate wire?

That wire is indeed the tacho signal wire for the stock cluster... But that's not the same as coils unfortunately... The tacho signal is 5V, the coil signal is not 5V... Hence no movement...

The coil signal is down the frame towards the coils, yellow/blue for one and blue/yellow for the other... Have a look here... It should help some...

ouch!!! that hurt my thinking parts....

okay that is an illustration of what i already understood... why does that yellow green wire not work? are you suggesting i connect to the wires between the coils and the ignition cont unit? im lost brother.. why would this be sofa king complicated

Because it runs on computer voltage, 5vdc. The coils are 12vdc.

The wire you are using now goes 0-5-0-5-0-5... The other goes 12-0-12-0-12-0-12... The tacho is nearsighted and doesn't see stuff smaller than 11...

Doeas that help yer thinking parts...

Yes, the two wires between coils and ignition unit... just pick one of them...

And BTW... That's tongue in check... If anybody missed that...;)

Also remember that it's a wasted spark ignition, so that might have an effect on your tach readings...

ok thank you all for the help i will post back tonight of my conquests....

alright im connecting to the yellow/blue wire that runs from the coil to the converter unit from #2 why is it still not working? i tried it before and after the connection to the rest of the harness... still nothing? is it possible that this tach doesnt work with our bike? im really starting to get worried.. i am way past the point of no return to go back to stock....

What brand of tach are you trying to hook up??

its litterally the cheapest one i could find and i know it only goes to 8 and our redline is 9and change...

FYI the VTR engine can spin past 10k...... in fact the factory rev limiter is at 10.3k ;)

sorry i didnt mean to say 9 and cange i meant 10 and change thank you sooo much for you technical guidance i will now go fix my bike and ride off into the sunset... you gaint floppy dildo...

i dont know about you bad asses but i rarely take it past 7k... just my riding style i dont need to go fast on the streets my apologies in advance if this insults you...

Well at least my tach works...... I'm not even going to bother with a come back to your insults. Have fun with the POS you bought as I have much better things to do than to try and help such a fine member as you.

Carry on.

yup your tach does work... and right now i wish i had never started this build but i did. and addmitedly calling you a dildo was a bit of a dick move sorry i just woke up with no patientce today and your little gem of knowledge grinded me the wrong way. not in anyway your fault. so my bad. i already read your sig and dont expect any helpfull insight from here on.. i just dont want anyone else to think im actually THAT nice to EVERYONE i dont know...

fuck.

Well at least you have come to your senses..... We all have had frustrating moments and I was wondering how just correcting so misinformation that you had post deserved being cussed out.

Good luck with your project.
