I screwed up

In an effort to clean up the wiring of several farkles on my 2003, I purchased and installed a Fuzeblock. The idea was to have it power my GPS, heated grips and Stebel horn.

The rewiring project took place over several weeks (I work essentially outside and it's winter), and through obvious brainfade, I wired the horn directly to the Fuzeblock, bypassing the horn switch.

As soon as I powered up the 12v system, there was a flash and the horn's Fuzeblock fuse blew, as did the Honda panel fuse for the brake lights/turn signals etc. After replacing that fuse, and checking all the other fuses (and disconnecting the horn), the good news is that I am left with a bike that runs properly (30 minute test ride), has brake and turn signals, but has two problems:

1. the speedo reads 0 constantly; and
2. the FI light comes on solidly after about 10-12 minutes of riding.

Pulling over and turning off the engine temporarily fixes the light, but the speedo has not changed.

I have been searching and reading, but cannot find any information that might narrow this down. Does anyone have a suggestion for me, please?

Many thanks.

 

you gone through all the factory fuses and wiring? hopefly you didnt short anything out, and you just gotta find the right fuse that blew. good luck brotha

 

Thanks, but yes: I did check the fuses in all three locations.

 

Where did you tap into the the wiring on the motorcycle to get power to the Fuzeblock and what did you use to trigger it?

 

What else did you do and are there schematics, some pics?

 

Thanks, Toe. The Fuzeblock relay gets its power directly from the battery, and the relay is tripped by the red/black wire in the four wire connector behind the R/R (as suggested for the VFRNess).

 

I know you said you checked your fuses but make sure to check them with a voltmeter rather then just with a visual inspection. While I never had the problem on the bike, one of my cars used to eat fuses and sometimes just visually inspecting the fuse didnt reveal anything.

 

Will do, and I am not being a smartass, but you mean an ohmmeter, right?

Thank you and I will report back.

 

Thanks, Reg. The lights all work, as does the tach. You and I are on similar wavelengths, but I hope to be wrong.

 

Can you check the code associated with the check engine light? That may be the clue you are looking for. I am thinking the display is going to be OK as it reads 0mph but that the signal is lost from the speed sensor and the code may lend to a circuit that is closely related to it. You may also want to check the speedo sensor connection closely as you were in that general area , could just be that simple. Not sure if the speedo sensor will flag a code or not and my sevice manual is at home, will look tonight.

 

Yeah check engine and FI are the same thing in my brain. I had a problem with 02 heater circuit on mine for a while and it would come on solid and would also blink with no rhyme or reason to it except it seemed heat related and took a bit of time to come on. The code would be very helpful in what direction to go looking in.

 

Yeah, ohmeter works too! I call it a voltmeter because the one I've got is a multimeter type dealy that does volts and ohms. I guess either would work; an ohmeter you could pop the fuse out and measure the resistance across each side. Where as a voltmeter, I think you could leave the fuse plugged in and test from the little open test leads on the back of the fuse itself.

 

There is a in-line fuse in the recall front harness, a 20A in a white casing that can be seen below the right headlight dustcover. I can't see it causing the problems but...

 

Thank you. I am going to spend some time on Wednesday following up on everyone's suggestions. I have discovered that the solid FI light means one of:

1. Short circuit in service: check connector
2. Faulty ECM
3. Short circuit in service: check connector wire

I am hoping that I inadvertently dislodged something.

I'll check in when I know more.

 

Just got home and checked the 02-03 diagram and the wire you connected to for the horn is the common 12v supply for the the horn and speed sensor on fuse "E". Double check that and report back please. I am very curious.

 

Will do, but cannot today. I will check it Wednesday and advise. Thank you!

 

ARRRGH! I hate cliffhangers!!!

 

Fuse E is good (verified with ohmmeter). As are the other fuses in the right side fuse box. It's getting too dark and too cold to find the fuse by the right headlight, so I'll have to get back to it tomorrow.

Thank you everyone.
