from original gauge to single Koso gauge

PostAuthor: XV1100nrk » Thu May 18, 2017 9:14 pm



Hello Fellow Virago Riders!!

I have an 87 xv1100 that I need some help with. Soon after getting this bike I laid it down on a steep gravel driveway and broke the Speedo. I haven't done anything to repair it as only the speedo was damaged and everything else still functioned properly (Tach, signals, oil light, gas light, highbeam...etc.) but am now ready to get new gauges. I thought I would simplify and go to a single gauge. NOT SIMPLE. I received the gauge today and was overwhelmed with the installation instructions. So I am asking if anyone here has gone to a single gauge, and if so, what did you do and how did you get from point A to success. Please help!

Live long and Ride,

Howdy. Welcome to VTF.

recommend putting your location in your avatar, it helps since there are slight differences between certain models - export vs domestic, etc.

for my clarity; you are combining tach/speedo to one unit, not deleting things / going 'bare-bones', correct?

ground issue...or something

PostAuthor: XV1100nrk » Mon May 22, 2017 6:12 pm

I am new here, so if you have the patience, please correct my wrongs!

I am trying to put a new gauge on my 87 virago xv1100. I dig the single gauge look, coupled with the T-bars, the bike will look great when the task is completed. However, I'm struggling with finding a good ground from the wiring in the headlight. I've read countless posts on VTF about the suggested ground locations and none of them seem to lead to the wiring in the headlight. As far as wiring ANYTHING I am a newbie. So far on this bike I have removed and cleaned the carbs about a dozen times, replaced the front brake pads, added an extended brake line (dot approved) so that the risers + tbars height doesn't put strain on the brake line, and I've done a front and rear tire replacement by hand. I'm saying all this because from some of the posts I've read some people on here will only respond if they think the person they are responding to has done actual leg work on their own for their Virago. I understand that so I'm trying to show that I love this bike, and i'm not just looking for an easy 'tell me what to do' out while working out my bikes issues.

That being said...keeping it short and sweet from here out....i need a solid ground for the gauge and am having trouble finding one near the headlight wiring harness. I've been told a black wire and their are few to choose from...the one I did choose isn't working.

Wiring scares me. I worry I will short out something or something worse and the bike will never run the same again and its take lots of effort to get it where it is today....well before I decided to put a single gauge on it that it.

If any help can be given...I would be extremely...EXTREMELY grateful.

1st please do as mark75 suggested and add your location to your profile ucp.php?i=264

As far as a ground, just ground it to the frame, you don't need to connect it to an existing ground.

mark75,

Noted, I will update my info.

Followup, I am not going barebones. Its a digital multifunction gauge that I'm installing. It has a fuel gauge, blinkers (L,R), RPM, Speedo, etc. all in one. The trouble is that as of now when I turn the key on the bike nothing happens. The bike isn't getting any power and neither is the gauge. I've followed the wiring diagram that dan on VTF supplied coupled with the diagram that Koso the gauge company provided and also...can't find a solid ground in the headlight wiring harness. It seems that the only place a solid ground can be found is on the frame of the bike of the engine. But the ground wire coming off the gauge isn't long enough for those locations. I'm kinda stuck...or at least I feel like I am... :db: :ops:

help

the Gauge I have purchased has speedo and tach in one. so... straying from stock gauges/fuse box to single, multifunction gauge. I'll need to get a separate wire (extended) to ground the gauge to the bike.

TRV,

I was unaware I still needed to keep a fuse box. As I mentioned, newbie :ops: . I was assuming that the power and wiring rearrangement was enough to route all signals and such properly. From your question about what i'm using as a fuse box makes me think I will need one. womp womp.

I have purchased a Fuse block and am going to attempt to button up the issues. I'm doing some reading on here about that process...here I go.

yes..... if getting rid of the factory cluster assy and going aftermarket you NEED fuses.. very simple to install a aftermarket fuse box.. let me know when you get it and i will help in wiring it up.

a 1100 will have 4 wires coming out of the ignition switch.
blue, tan, red, red... here is a diagram
http://www.viragotech.com/wiring/86_96_us_XV1100.jpg

red is for the hazards
blue for the lights
tan for the signals, horn, neutral light, brake lights
red for battery power in.
kinda confusing with the diagram due to the hazards are usually red/yellow and not red..............dan

that's a cool unit. it will look really slick, :thumbs:
so be sure to take pics and show-it-off to us, and I wouldn't be surprised others will be asking for input on their conversions.

I have attached an image of what the fuse block i purchased looks like. the fuses from the original box are 2 10 and 2 15. I so gratefully accept any help with this. I also have some quick splices (because I thought I would need them) and some extra wire for the ground. Due to rain today I wasn't able to try and tackle anything more than just the purchases. I'll be back at it tomorrow.

Thanks TRV and Mark75 :cl: :id:

are you keeping the hazards?
do not know that fuse box very well but with some playing we should get it to work.
looks like 1 input and 4 out.. i could be wrong..
how to test. you will need a test battery and a test light. run a battery power wire to 1 terminal of the fuse box. use the test light and test the other 4 terminals. how many light up? if only 1 terminal lights up then add another power wire to a dead terminal of the fuse box. again check how many terminals light up.. you may have to try different combinations til all terminals light up.. once you find out how many powers in we will go from there...

that speedo will need 2 diodes to get the turn signals to work.. also looks like the speedo works off of a wheel sensor............dan

Re: removing gauges

PostAuthor: Brodie » Fri May 26, 2017 6:13 pm

Holy thread nercomancy!

Just to give an answer to this and so people know it can be done and the thread locked if mods want here is what I have done.

The indicator lights between the Tacho and Speedo contain the fuse box on the XV1100 (at less it did on mine). When you want to remove the original gauge cluster you will also need to buy a 4 block fuse holder. There are two 10amp and two 15amp fuses that will need to be moved over to the new block.

I removed the original fuse holders which are not unlike a spade terminal and am using them until I finish the wiring and install insulated connectors. There is a small amount of wire trimming required to make this work but if you are installing custom gauges you should be right. I have fitted a small fairing and fitted the small use block to the mounting plate.

Re: from original gauge to single Koso gauge

PostAuthor: XV1100nrk » Fri May 26, 2017 7:26 pm

I never use the hazards so I don't really need to keep them. So the Fuse box has 5 prongs on each side (10 total) and 5 ports for two prong fuses. The box seems much simpler than many other examples that I've seen online and this makes me concerned. I'm not saying it will be easier but I am wondering if there is a better box I should go and get to avoid hassles that a this smaller, simpler one might turn up moving forward.

This may seem like a silly question...but couldn't I test the fuse box once everything is hooked up...by riding? The recommended tests requires me to purchase those instruments...I will if its absolutely necessary...but I was wondering, is there another way?

i did not see 10 terminals on the box you bought. its a simple power in power out fuse box. very simple to hook up.
use the 2 of the 3 ignition wires. the 4th wire is battery power for the hazards and dont want to use that to power loads. red is battery power from the main fuse.

you will use the blue and tan wires to power the fuse box.
blue in 10 amp fuse blue out for tail.
tan will power 3 fuses. so you need to split the tan to 3 fuse box terminals.
1 tan in 15 amp fuse red/yellow out for headlight.
1 tan in 10 amp fuse red/white out for ignition and oil level light.
1 tan in 15 amp fuse tan out for brake lights, signals, horns, tach, neutral light...................dan
