Wiring connectors 82 Aspencade gauge set

[Joneszy]

I have been trying to find a wiring diagram for an 82 Aspencade that shows the function of a three prong connector attached to the gauges. The wire colors in this connector are 1. Pink 2. Blue/white tracer 3. White/ Black tracer.
Need the info as I am currently trying to convert an 83 aspencade from digital dash to the mechanical gauges of an 82 aspencade. Any help much appreciated as the diagrams I have found so far are not readable.

Those wires are for the rear shock air pressure warning light.

[Joneszy]

Dave I want to thank you very much for the quick reply. You have saved me a lot of frustration looking for this. The 83 does not have a rear pressure warning light as it is deemed to be safe to ride with 0-57 PSI. I will be able to disregard this connector while trying to match the 82 guages to my 83 Aspencade.

What was wrong with the digital dash?? Curious, as I had two '83 Aspys (and one parts bike), and the dashes worked (and work) fine on all.

Cosmo the 83 dash was & is still in fine working order but I have made a naked wing out of this bike and it just seemed like it needed an older style gauge set up to give it the right look. Trying to make a cutting horse out of a thoroughbred!

[jeffcosmo]

Gotcha. I understand. At my job, there is an Aspy that has been nudified, but with digital dash intact, and it doesn't flow.

Coming back to the well again. I have figured out most of the wiring on my switch over to 82 Aspencade gauges on my now naked 83 Aspencade BUT now am having problems getting a reading on the temperature gauge.
1. There seems to be a difference in that the 82 and I'm guessing any wing that doesn't have digital dash has a one wire sender while the sender on the 83 is two wire.
2. I was hoping that the 83 sender would still work. If not I have to take apart quite a bit of stuff to gain access to changing the sender.
3. In looking at a fair # of wiring diagrams it looks like the older style gauges have a dark green wire with black trace connected to the temp gauge.
4. I have a dark green with black trace wire unused so far available in the harness of the 83 aspencade.
5. I cannot locate a dark green with black trace leading into the 82 gauges salvaged from an 82 aspencade carcass.
Anybody have any idea what the problem is? I am at wits end. Should I be able to get some kind of reading from the 83 aspencade on the older style gauge? Seems like a few folks here have a good handle on wing wiring and I am hoping for some help'
Thanx Jonesz

The temp gauge wire on the 82 is green/blue. I think you might make it work by grounding 1 side of the sender.

Hello Dave, I do have a green with blue tracer connected from the gauge set to the green with blue of the wiring harness on my 83. It is very cold today and supposed to be -25C here tonight (normal low for this date is -7C). Too late in the day to go out and crank the heat in my shop so will look at your suggestion tomorrow. I am having trouble reading the diagrams I have. My old eyes aren't what they used to be. Can you tell me what the purpose of the Green with black tracer is? Or where it leads to (maybe the voltage regulator)?
Thanx for the suggestion and confirmation on the G/blue wire

Best I can tell, those spaghetti diagrams are hard for me to , but it looks to be a ground wire. It goes to the instrument cluster and a splice leads to the - side of the accessory terminal in the fuse box. Usually a green with a stripe is a switched ground but not always.

Thanx for the info Dave

Was just out trying to track down my elusive temp gauge problem:
1. Took the back off the gauges and there is a common connector for the green/ black tracer. It goes to the fuel gauge(which also has a yellow wire/white tracer and the temperature gauge (which also has a green wire/light blue tracer).
2. The fuel gauge appears to be working fine and reading approx what it should for the amt of fuel in the tank.
3. From this I am assuming my 7V regulator is functioning properly.
4. I am now thinking that the 2 wire temperature sender on my 83 has to be in some way connected to the green wire/black tracer as a ground (as Dave suggested a keyed ground).
5. As stated before there is an as yet unused green/black trace wire in my 83 wiring harness.
6. I am thinking that if I bring a newly installed green /black connector from the back of the temp gauge to the available wire on the harness that it will function as a proper ground set up for my 2 wire sender
7. I cannot find a readable 1983 wiring diagram to actually find out what color wires lead from the sender and I cannot get close enough to the sender to check.
8. Really would appreciate it if someone who has a readable diagram would check to see if this is the thing to do as I don't want to screw up the coils in the gauge if wrong but the green /black tracer is now 7V if coming from the regulator right?
Maybe someone has another suggestion as to how to troubleshoot the sender wires? I am stymied as my go to mechanical guy is away on holidays.
As always any help appreciated. If I could get info on the two ewire colors on an 83 Aspencade temp sender I think my problem would be solved.
Sorry for the long post but tried to answer all questions you might have.

The second wire from the 83A sensor is G/Bu, try temporarily grounding the G/B wire.

[WingAdmin]

Do not ground the Green/Black wire! That is the 7 volt feed, connecting it to ground will blow your 7 volt regulator.

The green/black wire feeds a regulated 7 volts to both the fuel and temperature gauges.

The Yellow/white wire runs from the fuel gauge down to the fuel sender. The fuel sender is a variable resistor that has one side of the resistor connected to ground.

The Green/Blue wire runs from the temperature gauge to the thermistor, which is a variable resistor with one side of the resistor connected to ground.

If you connect the green/blue wire to ground, the temperature gauge should go to full-scale deflection (all the way to the right). It will move slowly, as it is heavily damped.

If you connect the yellow/white wire to ground, the fuel gauge should go to full-scale deflection. It is also heavily damped.

Well procrastination paid off for me this time.Thanx for saving me from that Wingadsmin. So the 7V is OK I am thinking as the fuel gauge works. I am still in the dark as to where to green with black in my harness goes to, but just now read in the Honda Gl1100 manual that the resistance test for the 83 aspencade temp sender is to use an Ohm meter and test the resistance across the Green/blue and Green/black at the green 6 pin connector. So my non electrical brain if there is such a thing says that the green /black wire in the 6 pin connector (which is not being utilized by me at present) goes to the temp sending unit? Will try your other test on grounding the Green /blue to see if the gauge slowly goes up to top end. Can't figure out why the sending unit on the 83 Aspencade has two wires tho. Suppose it is due to the digital instead of analogue gauges. That being the case I might have to find a temp sender from an analogue gauge equipped bike right?
Once again thanks for the help, will have to continue this another time as have company just arriving.

Are you looking at the 83A diagram? It in fact does as you say on every 1100 except 83 aspencade, unless the Honda diagram is wrong or I have misread it. My eyes are not what they used to be so I have to use a magnifying glass to see those so it could be me.

As eye see it, yes the green/black does go to the temp unit and also there is a green that ties off and goes to the acc fuse. Now the other green/black you have unknown hanging down just might go the speed sensor on the front wheel.

So the one I have "unknown" Green/black must lead to the temp unit and tied into the acc fuse. The speed sensor is no longer on the front wheel as I have removed the digital sender and am installing a regular cable from an 83 standard. The speed sensor is now in the 82 aspencade gauge cluster fed by a white wire/black tracer. At least that's what I am hoping.
Am going to try Wingadmin's suggestion of grounding the green/blue trace wire to see what the gauge does. If it activates properly will likely take some stuff apart again and install a temp sensor from an analogue 1100. I have since read where the resistances are different on the two wire 83 aspencade sender from the other earlier one wire temp senders so may give a faulty reading anyway.
Thanx to all for the help so far. I will let you know when I do the testing and sender replacement.
