750 SECA Computer "Bypass"

I recently removed the square headlight and the square fog light in favor of a 7" round headlight with built in fog light. Of course, now the stock cluster looks worse than it did before. So I am swapping out to some round gauges from an '88 fz.

I want to remove the computer from the bike completely. The problem is, bike won't run without it. I am assuming that with a snip here and there with a little re-wiring, this should be perfectly fine. I have been over the wiring diagram in the Haynes manual, and I think I got my game plan down.

Has anyone done this with any success? If so, can you offer any words of wisdom?

 

I got rid of my computer with success. It's not as hard as it may look. First of all, it's not really a computer that runs the bike. It's just a monitor for the various sytems to watch them for you. Removing it will not make any difference in how the bike runs, really. Don't believe me? Just ask me!!!
OK, so first you will need a wiring diagram for your bike or you will be pulling your hair out by the time your done. I used one from my Haynes manual that shows all the wires going into and coming out of the computer/monitor.
Now I only kept the wires for the headlight, turn signals and the wires that illuminate the speedometer (needed those for the new speedometer I installed)
I only kept the wires I needed and sealed off the rest and tucked them away behind the new (round) headlight incase I need them in the future.
The wires for the headlight and signal lights go into and come back out of the computer/monitor, so you will need to find those and label them so you can connect them together later. Also, there's two wires for the highbeam indicator you might want to label, if you will have an indicator light with your new setup?
The signal lights are the same - there are three wires you will need to find and label. One for the left signals, one for the right signals and one is the ground wire, shared by both of them.
I don't need the sidestand wires (I know when it's down or up)
I don't need the oil light (I watch my oil thank you very much)
I don't need the brake and headlight monitor (I can see when they work or not)
I don't need the battery light (I have a volt meter running straight off the battery so I can see it's conditon)
And I don't have a fuel gauge anymore, so those wires are tucked away for now too.
I don't even have a tach anymore! I figured I never got it close to redline as lng as I've owned it (7 years now) so why have it?
I now have a speedomter mounted on an aluminum plate bolted to the top of the upper tree. I have 4 LED lights to monitor what I need. I have a red LED for the highbeam (couldn't find a blue one just yet) A green LED for nuetral, and two amber LEDs for theright and left turn signals.
It's not to difficult if you can find the wires going into and coming out of the computer and where they go to.
Here's mine now:


I also now have heated grips and a cigarette lighter, so I mounted a plate on the handlebar clamps for them. I have speakers behind the windshield that run off a little amp, mounted under the tank, so I have tunes when I ride! It may look kinda tacky, but it's functional. >PD<

 

geez buddy, whats your damn deal? i mean come the hell on, you answer my question quickly, exactly, and show some pictures of a sweet setup, all without flaming, yelling, or using obscenities. You got a real problem buddy! :lol:

but for real, i have seen the picture of your speedometer upclose and i really like it. i am in the process of fabing something similar, but i will have a tach. not that i have ever reached redline, i just like the dual guage look.

Thank you for the info.

 

OK then, good luck with the project.
I like the speedo mount I made, however, the added plate for the grip heater switch and lighter don't cut it for me. I'm thinking now I need to make a mount for the speedometer that incorperates all the switches and lights in one location instead of like they are now.
I love fabricating parts, so it will be interesting to see how it turns out. I'll post photos when I get it done. PD

 

you said those are leds below the speedo? how hard was that?

 

No actually it was pretty simple to make the LEDs fit. They are from Radio Shack. They have a screws on the back side to hold them in, so all you need to do is drill the proper size hole and slide them in from the front and tighten the screw on the back. Then wire them to the correct wires and your done!
The plate I made to mount them and the speedometer in is aluminum. I fabricated it from an old road sign (no I didn't take it down, I got it at a job site in the trash) I found old road signs are perfect for making things like the side covers, etc. It's just the right thickness for bending and it's strong enough to holds it's shape. Then all I had to do is sand it good and paint it. (I use primer, base coat then clearcoat it) PD

 

Burn,

I wish you the best of luck, but I have one question.

"Have you added yourself to the xjmap?"
Us Texas guys have to put some representation out there!
No taxation without representation!!!

@ PainterD

Went to Radio Shack on lunch break and bought 2 yellows, a red and a green. Got myself a project for this weekend. Thanks again.


@ Ass.Fault

Just added myself!

 

I see you didn't get blue LEDs? I wanted one for my highbeam indicator, but maybe they don't even stock them. Looks like another trip to ebay.

 

they claim that they don't stock blue. i'd have bought you on if they did.

 

Gee thanks for the offer!!!
No big deal, red will work for the highbeam for now. I just got used to seeing blue, that's all.
I might just look over on ebay and get a whole pack of different colors so I have them when I need them for other projects.

 

Here's the LEDs I have mounted below the speedometer. The speedometer is mounted in an aluminum plate I cut and bent then painted. Then I drilled four 5/16" holes below the speedo for the LEDs to mount to. They have screw on backs to hold them in place.
