Some bikes just ain't got no class!

[Trader]

Including my 88

 

 

I don't know what Carl did when he put the trunk box etc together on my bike

 

.... but my class WAS working before I tore everything apart.

 

Now it is dead....nothing....no display....no clicking....zilch...zip...nada.

 

 

 

 

Where do I start?

[mother]

check to make sure the display unit is plugged in.

 

i would check fuses to see if one is blown.

 

cheers, Scott

[Condor]

Check the power plug back near the pump since you were working on the trunk. Probably unplugged....

[Flyinfool]

My 88 never did have class, maybe that is why it fits me so good....

[Trader]

well it looks like I'll be replacing the fuse block at least.

 

It has a real dog's breakfast of added fuses, replacement fuses and some in the original glass fuse block.

 

One of those fuse holders broke off so I may as well replace it. I was going to wiat until winter but looks like I gotta do it now.

 

Anyway....as far as the class....there is power to the control unit as the light comes on when I turn the key.

 

I tried my Class controller from my 83 and it didn't work either so it probably is something at the back. I'll just have to undo what Carl did....again!

 

We spent most of the afternoon undoing what we had done (or more correctly...whet I had done)

[Guest Swifty]

so much for the theory that white shirts make good mechanics.

[Trader]

Well, spent the evening figuring out the wiring and changing the fuse block.

 

That's not really true...I didn't figure out the wiring much at all!

 

The PO had all kinds of extensions with inline fuses to replace some of the glass fuse block that had fallen apart.

 

Here's some pics of the before and after.

 

 

I have a question for you

on the 3rd picture, you can see the area I circled.

There is a red wire (arrow) that seems to go down to below the rad. I'm not sure if it is the starter unless the starter wire goes up from under it.

But if it IS the starter, why is it on the NEGATIVE side of the battery. If it is the ground....they should have used BLACK!!!!!!!

 

 

There is a rectangular fuse box in front of the battery. It has 4 spade type fuses in it...but I have NO IDEA what they may be for:think:

 

Also, right beside the one red wire, is a heavy red wire with cloth covering...goes into a 2nd fuse block containing 2 glass fuses. Smaller black wire coming out.

 

What is that one for?

The heavy red wire and two fuses is for your CLASS (one fuse is spare)

That wire looks like an aftermarket ground that replaced the smaller guage OEM. Rather than use the correct color code they made both cables out of the same color.... Check the other end on the frame just above the water pump to see if it's the same just to make sure...

I checked the Class and made sure it was all plugged in, and asked you about it before I put the trunk on,,,,, soo I would suppose that if it was undisturbed it should work just fine,,,, I would fix the dog's breakfast first,,,,, maybe we should have spent more time on all those wires,,, I don't seem to mind them so much,,,,, maybe I'll have to come back to help you out again,,,,.

Just because the light comes on in the controller doesn't mean anything for the controller itself. There are 3 connections to the controller. Two single wires with spear connectors,, that's for the lights, and then there is a larger connector with about 6 wires in it,,, that runs the controller and feeds the important stuff in the back under the trunk. Two separate concerns altogether.

It is not easy keeping quiet when we are talking about Carl and Class

Talk is cheap,,, but Class can cost you,,,, now for Carl??????/ well I'll go to trouble another post now.

the rectangular black thing with red wire to the right of the five fuses... is a filter from Yamaha. The rectangular fuse box in front of the battery is for the CB, cassette and radio and something else I don't remember. Maybe the CLASS system........AND Thats one big ass wire I see at the arrow...maybe for starter...

The rectangular thing is the CLASS fuse in 2nd picture, it has two fuses in it, one is a spare.

So far I have checked all the fuses...One was blown in the Front fuse box...but it was suppsedly for the fan...which I probably don't even need this time of year.

 

I sprayed cleaner on the class connections (sq. plug with about 6 wires) and plugged/unplugged a few times.

 

Still noting to the controller.

 

can anyone give me readouts I should have from the sq. plug...then stand by for more questions!

 

If all else fails, I'll be looking for volunteers anywhere in Ontario (well, Maybe south of North Bay) or Northern NY. I can come to your place and perhaps we can get it fixed.

 

Supposed to be good weather this weekend and I was hoping to get it done so I can go get my trialer from Jim's in Rochester.

Start looking at a second Gen?

 

Sorry I'll go back to my corner

Are you sure you have the ignition in the acc position????

[Trader]

Yeah....in ACC.

 

I've got more messed up than just the class.

 

My wiring is totally messed up. WHen I turn on the key the tach is showing 4000 rpm.

I tried the signals and the relay just buzzed.

 

The class is not showing ANYTHING (other than the light working)

 

I have checked all fuses and double checked wiring (I replaced the fuse block).

I took apart all class plugs, sprayed with cleaner, plugged and unplugged a few times.

Maybe it sounds like you have some wires wrong. I would check the fuse block. One side should have power when the key is turned on, the other side no power with the fuse out and the key on. Normally the left side would have power but the right side not.

That extra fuse block has fuses for Audio, Hazard Lights, Fan and Signals

So its fixed, Class running 4000rpm:bang head:

Just kidding,

Actually I think you may have unhooked a ground wire somewhere.

[Trader]

OK ....that's a start.

 

I have installed skydoc's fuse kit.

 

the top (front-ACC)) connector in the new fuse block has the red wire on the left, leading to the left side terminal block . In the wiring diagram is is shown as a black wire on the left side but the instructions, and . Earl told me to clip the black wire and cap it.

 

It's opposite wire...is supposed to be Red with a black stripe.

I checked...and it is correct...but the R/B wire is powered on the RIGHT (Correction)...even when fuse is out.

 

I can't see where the R/B wire goes to....I think into the wire harness.

Powered on RIGHT...not left!

On a stock fuse block, there are two terminals at the top of the block. The left one is the ground wire and the right one is the 12v+. The first fuse down (stock setup) will have power on left side with fuse out when key is in run or accy position. Right side of top fuse goes directly to top right terminal in fuse block.

 

I think Earl is supplying two separate terminal blocks for the accy connections from what I remember from his classified ad.

You know you'd be welcome here anytime,,, and you could even bring your 'vette,, and the bike,,, then we can fix it right,,,, just let me know.

[Trader]

WOOOO HOOOO!!!!

 

YAY!

 

WHOOPEEE!

 

bet you know by now.....it's FIXED!!!!

 

I had a R/W and R/Y mixed up...which fixed the ignition problem....then all I did was take apart the CLASS controller plug (again) sprayed cleaner on it(again) but it back together and it's WORKING!!!!

 

SO....now all I have to do is put it all back together again, blled the clutch...get a safety check and I'm ready to go!

 

So...I hope this good weather lasts to the middle or end of the week!
