86 electrical

Hey fellas, I know dumb question but, where on an 86 did the fuses go? Were they like the 87; in the indicator box? :unsure:

 

Good question, I have an 86 and have yet to look for them so Im interested to hear the answer. I thought I read somewhere that they are in front of the tank below the fairing directly below the front brake master cylinder but I have yet to look to confirm that or not.

 

I'm changing from an 87 speedo and tach to an 86 and want to know if I can use my box from the 87. Or, if there is a simple upgrade I'd be cool with that too.:smile:

 

I dont have a solid answer for you but if you pm me your email address I can send you a copy of the 86 owners manual in pdf format.

 

I have a repair manual but it doesn't really give any definitive answers. Sounds unlikely but I've gone over it twice. The schematics don't even say fuse anywhere.

 

Yes, I just read through and found the same problem. Tomorrow Ill have a look at my bike and see.

 

The 87 fuse box will not fit with 86 gauges. In fact in order to fit an 86 fuse block on an 87 bike you would need a 86 upper triple tree as the fuse block bolted directly to it. The 86 fuse box fits in front and over the ignition switch. Also youll need the 86 upper fairing/gauge bracket as well. I could be wrong about all this but I was going to do the switch on mine, had all the parts and then decided the time it would take to take the front end apart wasnt worth it and ended up selling all the 86 parts.

 

The Pacinator

Pac is correct. Insult to injury is the 86 had a cam sensor the 87 did not so if you put F2 87 dash on F1 86 bike tach will read half of what it really is. Anger.

 

JEEEEEZUS!! read you blinkin' owners' manual gentlemen !!

 

Out of respect, these are over 20 year old machines and a lot of us dont have said original owners manuals, dont be so testy.

 

I got an FSM on ebay for my 86. only thing keeping me sane through this electrical problem that I have going on here :crazy:

expensive but really worth it!

if you look, and correct me if I am wrong ( happens!) there are two main fuse locations. at the starter solenoid (30 amp), and at the triple tree ( assorted ratings) after perusing the FSM I only see those two locations.

the ones at the triple tree are as follows ( from left to right)
1 10A Parking
2 10A Fan
3 10A Ign - start
4 10A front pos. tail
5 15A turn signal, front rear brake light, horn
6 10A indicator
7 10A Headlight.

if you need wire colors let me know. I am going to try to make some 85 gauges work in my 86 I think. .... hopefully

 

I think what squirrelman was trying to say was tthat if you had the book from a 20+ year old machine thats been through an unknown amount of owners and it probably gotten lost over the years it may have the information you seek.. acctually does the owners manual have that.. I know the service manual has all that crap in it...

HEY SQUIRRELMAN >>> LIGHTEN UP A BIT WILL YA> NOT EVERYONE IS AS COOL AS YOU AND HAS EVERY BOOK ON THESE MACHINES>>> THATS WHY THEY COME TO THE FORUMS AND IF YOU SAY YOUR TIRED OF SEEING THE SAME OLD QUESTIONS... WELL DON'T READ THEM OR ANSWER THEM..... THOSE BOOKS ARE HOARD TO COME BY... IF YOU NEED CERTAIN PAGES LET ME KNOW I'LL TRY TO SCAN MY BOOK AND GET THEM TO YOU

 

Don't know if this changes anything but I'm putting 86 gauges on 87 not the other way around; with the proper upper fairing stay just not the 86 upper triple.

And Chipmunkdude, since I have an 87 and asking questions about 86, and I'm sure Honda never intended these 2 machines to swap gauges, then I guess I can ignore your funny little comment.:flip:

 

Supertex.
First, lemme say this. Motorcycle Parts, Motorcycle Accessories by BikeBandit.com has some pretty nice, searchable microfishe on file. Its quite simple to look up both bikes.

Second. to answer your question, "can you put an 86 instrument panel and fues box on an 87 frame? Yes, you can. However, keep in mind there will be several modifications you must do to make this happen. You will need to purchase or get a hold of the stand alone fues box from an 86 and re-wire the connections to match up with the wiring schematic for the 87 wire harness... I.e. match up the inlet and outlet wires from the CDI fuses. (this really isnt that hard). Next you will need to mount the stand alone fuse panel, in accordance with either your own method and afix it to somewhere under the new instrument panel, or, purchase/ get a hold of/ an upper triple tree from an 86, or drill and tap new mount holes on your 87 triple tree, or find another nearby location and afix the box so that it is in the best possible location away from the elements, including water spray from riding on wet pavement. Next you will need to ensure you connect the sensor wires for all the instrument panel lighting. Spedo and tach are fairly straight forward. Post this, there is a fascia cover which is used on some 86 models. I would locate this and put it on, else you will have your main wiring connection station there to the right, semi-exposed... (not safe).

Lastly, I want to just ask you a blank statement. before I do. I strongly urge you to double check ALL your wiring from the CDI. (some I/O devices are 3 wire on an 86, where as they are 2 wire on 87, and vise versa)... this being stated, my question is,

Why are you doing this?

If its a matter of broken 87 gages, be patient. I see instrument panels on ebay a lot. If its simply the look of the "dirt bike" style of the 86 gages, I want to again strongly urge you to explore ALL the wiring, or even entertain a total wiring harness swap, including the CDI with an 86.

If you still do it, please take pictures and keep us up to date on your progress. I must say, a partial electrical systems transplant does sound interesting if nothing else.

 

The plain fact is I have a straight 86 upper stay which will not mount my 87s, and 86 gauges lying here doing nothing; plus I do like the round better :smile:. All connections are matching up perfectly except the fuses not being present. I am prolly going to try the stand alone box and find my own location. All in all if this doesn't work I can put my spares on ebay and get OEM. Nothings ever permanent anyway.

Do I have to worry about this problem? I can see no differences between harness connections so far. Thanks:thumbsup:

 

Cool. outside of the look of the 86's you "could" make an adapter plate with different mounting pattern out of 1/8" thich cold roll steel, and paint it. the 86 and 87 are both Cam driven. I'm not sure what Toe Cutter is refering to... this doesnt mean hes wrong. Simply, I dont know about this.

I would do some diggin if I were you... then again, I never look at the tach to shift anyway.

 

Curious

Twenty years ago I tried to put f2 dash on f1 and had the tach issue. If you run f1 dash on f2 I would like to know what happens. Please let me know.:thumbsup:

 

Will do. Should be done this Thurs or Friday my off days. The tach is on there now and the speedo is next. I'm actually thinking of using my 87 fuse box and making a mounting plate since it already plugs right in and I think it has the same fuse set up.
