Hi everyone. I am in the process and near completion of converting my Interstate to an Aspencade SE. I know that sounds a little goofy but I wanted all the goodies such as reverse, cruise and air suspension and also wanted the lighted controls of the SE. At the moment I am having an issue with the turn signals. Neither left or right come on; not on the dash nor on the front or rear signal lights, but like many others have mentioned, the hazards still function properly. The left combo switch is brand new so I have ruled that out. All other lights including headlight, taillights, dash lights, side marker lights and reverse light function as they should. The other strange issue is that my after market cornering lights stay on all the time when turning on the key. Maybe they are driving lights and are supposed to do that.

I have scoured the Internet for answers and although there are some who have had similar issues, none really seem to apply to my problem when it comes right down to it. It has been a long project and now I'm down to figuring out all the little glitches before putting all the Tupperware back on. Oh, did I happen to mention that I repainted every single piece on my goldwing minus the saddle bags? Yep! I stayed with the original Candy red spectra color and had it mixed in aeresol cans at a local automotive paint store. Tri coat colors are fun to work with and the results were very pleasing for being my first time working with automotive grade paint. The paint matched my saddle bags nicely. I didn't paint those because they were in near perfect condition with no fading of the paint like many of my other parts. Wow, talk about becoming really intimate with sandpaper as well as with my wing.

So anyway, I hope someone out there can lead me in the right direction. Amazing how something that appears so simple can prove to be so complicated. Btw, all fuses and relays are fine. I will post this same topic on the other site with hopes that all minds can come together and help ease my pain. Thanks in advance for the help.

Hope you have the electrical troubleshooting manual. You are going to have to go through it point by point for instance do you have power to the flasher and is it grounded when you move the switch to the left or right?

Don't rule out the self cancellation module in the tripple tree. Just a thought or my 2 cents worth.

I do have a full service manual with electric troubleshooting manual and its not helping much. Basically all there is regarding turn signals is a schematic. And I'm not sure how to test the switch. That's what I need help with. But again, the switch is brand new.

Yea I have read about that module causing havoc to some. But that area was never messed with. And I'm not sure how to access that module. Maybe I'll be old school and just go back to the days of using hand signals. :ROFL:

Light bulb came on. Does my theory hold water???

Okay so I am lying in bed thinking...maybe my 92 interstate didn't have the self canceling turn signal feature, yet my upgraded SE left handlebar switch and Aspencade front harness are setup for turn signal canceling. Could this maybe pose the problem I am having; rendering the turn signals inoperable? Do I need to maybe add a turn signal canceling switch to my triple tree housing that has never had such a switch before, to possibly complete the circuit and make them work? Will my interstate allow such a switch to be installed even though it was never designed to house it? And finally, is it possible to bypass the turn signal cancelling and complete the circuit that way. i could care less about this feature. Can anyone chime in and let me know if this theory of mine makes sense and give me some advice? Are we aware of anyone else who has converted their Interstate to an A/SE?

Yes you do have to have the cancel unit if you are using the rest of the system from an aspy.

I believe the Interstate has a much simpler mechanical type turn signal. The Aspencade and SE use an extra module that is not in the Interstate. That module has inputs from various sensors (that don't exist on the Int.) and is quite sophisticated. I'm guessing even the switch is different. Why not leave the original lights as is? Maybe more info would be helpful? Are you changing the harness? How do you plan on getting reverse? Do you realize the scope of the work you are taking on? Might be more than you planned for.

Actually I don't have the cancel unit since it was an interstate and that's the problem.

Thanks for your concerns. I have everything for reverse, cruise and air suspension installed, including new harnesses, control units, cancel switches and relays. Also required changing out the right control switch assembly, gauge panel for the reverse and cruise lights as well as a different carburetor. It's really not that difficult to convert, just time consuming for research and installation. I think everything cost me around $650 and I gained a ton of knowledge in the process. The Air suspension works great, the cruise has yet to be tested and the reverse is almost ready to be put to the test. Yes there are a lot of items required to do the change over but with the help of a service manual and eBay for parts, I am nearly complete. As for the turn signal issue, I figured out the problem. I need the cancel unit. I ran a test by grounding the blu/blk wire from the C90 brown 6-pin connector which is located under the front left fairing and the turn signals came to life. The C90 connector is what connects to the cancel unit located in the triple tree. So I bought a used cancel switch and sub harness this morning on eBay ($20 for everything) and will install it when it arrives. Then I'll move onto the reverse. Thanks everyone for your input.

yep. You'll prolly wanna pull the switchs out of the grip-cluster and swap em. The SE switch used the self canceling stuff to 'latch' a ground to run the signals until either a set number of speed sensor pulses (at about 35mph or more) or the tripple tree was turned. Without a full harness change, you'll not have the wiring for the cancellation unit. Easiest would be to retro-fit your Interstate's turn signal switch into the SE grip cluster and forgo the self-cancellation feature.

Hey Satan. Actually it's had a full harness change including the Main, Front, and Rears. Not one bit of wiring on the bike is from the Interstate. And every connector is terminated except the C90 for the turn signal cancel unit so I think I should be good to go. The only thing I had to do out of the ordinary was tap in to the right side marker light for voltage for the illumination of the right handlebar combo switch. The left combo switch illuminated automatically when I connected it for some reason but the right didn't. The pins in the wire connector were not there for the illumination of the right side switch since I used an Aspencade main harness instead of an SE main harness. I also upgraded the light bulbs inside to blue LEDs and they look awesome. I then upgraded the instrument cluster to blue LEDs and its very cool looking. Reverse is next on my list. It is installed and the reverse light comes on when the engine is running, in neutral and reverse lever up. But when I push the start/reverse button, it only clicks with no movement from the rear wheel. I can't test the cruise yet until everything is back together and I can road test it but all 4 cruise cancel switches have been installed as well as all the other cruise components including the module, valve, accumulator, etc. And the cruise light does come on when I press the button. The air suspension works perfectly. Like I said, reverse is next, then cruise and then I am ready to ride it for the very first time. If you have any suggestions on the reverse from what Ive told you, I would love to hear them.

well, if it's a full harness, then you could prolly 'fake" the turn canceling unit's ground and get things running as is...

The Blue wire (with Black stripe) at the turn cancel unit connector should be grounded for your signals to run. In "normal" operation this wire is switched to and held at ground until the signals are cancelled by the unit itself. So... if you've got a 100% harness replacement, grounding that Blue (w/balck stripe) wire should get you some blinking....

Yep, it got me blinking. Now I'm on to the reverse issue. I started a new thread on this. Maybe you can help. I think you prolly have the most brilliant mind on this site from all the posts and threads Ive read from you. Can you review my thread and give me some help in where to begin. Here is what I have posted...

Interstate to Aspencade Conversion...Reverse Problem

"Okay, with the help of Virgilmobile on the GoldwingDocs Forum, I was able to figure out my turn signal problem so I decided to start working on my reverse issue early. Please note that I have converted my 92 Interstate to an Aspencade. I have all the harnesses, relays, sensors etc. switched over so there are no issues with missing components. Here is what is going on with it:

I start the engine while in neutral. I engage reverse by pulling up on the handle. The neutral light goes out and the reverse light lights up. I push in the start button and I can hear the starter making a whirring noise like its spinning but no wheel movement. While the starter is spinning, the engine idles down. I then spun the rear wheel and it is locked in place and will not move while reverse is engaged. When disengaging the reverse handle, the rear wheel moves free again. So it appears that the system is working and that it is not an electrical problem but instead a mechanical problem. As a side note (likely unrelated to the reverse issue) when I turn the ignition off with the key, the engine keeps running. It only shuts off with the on/off switch. Where do I begin with the reverse issue and what would cause my engine to continue running after turning off the key? Thanks in advance for all who help.
