wiring

I recently bought one of the KOSO DL Tachometers, installed it on the bike, wired the signal wire to no.1 cylinder, started it up and all was working fine. I took it for a 20 min test ride and the tach worked fine for about 10 min. Then the RPM display went to 0 and wouldn't move. It would...

I just got my t-boost and it came with the 3 position switch. Here's how it is currently wired. UP - 3K boost activation center - boost completely off DOWN - 6K boost activation (stock setting) I have two issues: a. I don't really care for the center position (boost completely off) and b...

Hi all: I'm currently installing a Virago tachometer on my Max, and I got no result from wiring directly onto the the signal receiver on the stock tach. So, my question is this: What should I splice the Virago wire into to receive a strong enough pulse to make it "work"? (Please note that...

Does anybody know if you can purchase new (OEM) or aftermarket (new) wiring harnesses for and '88 max :ummm:

Okay, I need some advice. My charging system was kaput. Took the bike into the dealer and for $100.00 they told me the regulator/rectifier was bad, and further that the stator was putting out low voltage. So I installed a new stator. Sean sent me a brand new regulator/rectifier. This is where...

Anyone have experience with deducing a wiring issue on a vmax? I have no blinkers, rpm gauge won't work, temp gauge won't work and the fuse that controls the entire system keeps blowing out when I replace it and turn on the blinkers. How do I go about deducing what the problem is? I see...

I have acquired a replacement for the plug in connector at the stator (generator, alternator, magneto etc.) These are a direct replacement for what is on the 1st gen bike from the factory. General recommendation is to eliminate this connection, I am aware of that. However, I prefer to have...

Below is a link to a PDF file for the 12N (85-89) VMAX Wiring diagrams. About 1.6 meg in size. http://www.vmaxforum.net/local_links.php?action=jump&catid=2&id=67 This has been redrawn from Yamaha's schematics in a format that I hope you will find easier to follow. I put it in this forum to...

Would any one have a color electric diagram. The one in the service manual is unreadalbe when zoomed. Max

Hey All, I have a 93, I'm replacing the instrument cluster with a new Acewell unit. On the diagram, it looks like I'm supposed to wire some of the connections to the negative side of the of the switch (the oil level for example). It looks like I have to run a wire from the ground side of...

"Tach Input - From Tach line of the engine computer or the Switched Side of an ignition coil" Can I tap into the #1 coil RED signal wire for the tach pick-up for the shift light?? Same as I did for my T-Boost signal?? TIA........

Did a search but couldn't find the vendor from England that sells heavy duty wiring kits. He sells various versions plus manual radiator fan switches. The kits are supposed to fix grounding, crimp, R&R problems. He often has these kits on eBay but has none right now. Anyone have a link to his...

Got the oil pan back on last night, and the next step on the video was to reinstall the low oil sensor. On mine, there's no wire coming out of the sensor, but instead there's a screw in the opening, and kind of a 45 degree angle coming out of the hole. Is the wire supposed to be embedded, or is...

Hi, I was replacing my front turn signals and low and behold I forgot what colour did what, anyone help me with this issue? Thanks

Hey guys, about to pull the plug on some dual intensity led rear turn signals. My intent is to have them function as both running and turn signals. Wiring the turn signal portion will be straight forward. My question is on the running light wire. I was probably going to just tap into the...

Can any one help me? I have recently brought a 92 vmax and have some DIY wiring attached to the v-boost control unit which goes up to the clocks wiring loom. The v-boost kicks in at 6,000 rpm and there is no T-boost switch, so what is this wiring for?:ummm:

I have bough some aftermarket ones from ebay and have a question about stock 1's... In the stock electrical system, there are 3 colors for blinkers i believe. There is black, brown and blue. My question is: Which color is the Flasher light, Running light, and ground???? thanx

Found the bug in the Substation wiring today, My Buddy Chris stepped on it before I could shoo it outside...poor little guy...

Is there a way to enlarge and print the wiring diagram from the online manual and still maintain a legible resolution? It is hardly readable without enlarging it. Thanks
