Ok, DenverWinger, that's very valuable information. Yes, starter works fine. So I'll just put that bank angle sensor back in.

I don't measure any voltage to the fuel pump because I can see when it runs thanks to the transparent fuel filter. I tested the pump by jumping the battery to it.

and then, you are not approved until a human moderator can read what you say.
We restrict links and photos in the first 5 posts...
This gives the moderators a chance to learn about who you are.
Thanks @AZgl1800
I get that, the the site does have a robot detector now (those didn't exist when ancient PHP bulletin boards came around).



And really my beef is that you aren't told these rules beforehand (or they are technically there but buried somewhere), only after you violate them. That's the not nice part.



Ever had a job where the management's idea of training was to yell at you for doing/not doing something they never told you about?

Ok @redwing52 thank you for that! I'll check for pulses at PC2 / pin 8. Any idea where those wires go so I don't have to open the ECM again?



I suppose the pulses should be in the in the 0-20V scale on my meter, is that right?

We used to have a lot of info up front before people could register.
All of it was ignored, no one read it, people complained just as much about how the first 5 or 15 posts are managed, as they do now...


We used to restrict all links and pictures for 15 posts...
that rule was the result of a Poll by the members who were fed up to their necks with pornography and advertising for every thing conceivable.


Over the course of a couple of years, we moderators have asked the IT folks to tighten up the reins, and the result is what you just went through.
We dropped the 15 post count to 5, with heavy Moderator review of every New Member.... the only place a New Member can post is in the New Member forum.
This allows Moderators to see every new poster.....
Before our new rules, a porno jerk would register, ignore the New Members forum, and post up filth and crap in the Technical and General forums.....


That is not possible anymore.



for all who have more than 5 posts, they never see junk posts on this forum.
I think that more than out weighs a minor bit of irritation that you tried to upload a few pictures, and they were rejected.


Now, on with the show. over and out.

I looked into the Ignition Pulse Generator...


General info:
https://goldwingdocs.com/forum/viewtopic.php?t=30788
One example shows 11-tooth (12 position) rotor and some kind of pickup ; the other example shows a 6-tooth rotor and a 2-in-1 pickup set.



For 83 Aspencade:
https://goldwingdocs.com/forum/viewtopic.php?t=20196
Two hall-effect sensors and an eccentric cam.



For 96 SE:
https://goldwingdocs.com/forum/viewtopic.php?t=30788
Two hall-effect sensors on opposite sides of an (apparently) 12-position rotor ("trigger wheel"). I'm going to assume my 96 Aspencade looks something like this (when I find it).



I reason that since this detects engine rotation, this should not be interfering with the fuel pump before starting. Everything I've read says that the pump should prime for a few seconds when the ignition is on (and I suppose, the run switch is on). I have not seen this happen on mine.


While I was testing the pump with a jumper to it from the battery, I was getting ignition, but only (poor) combustion on the right side. I think this has nothing to do with ignition coils, as I noticed a lot of fuel dumping out somewhere under the left side. I have yet to trace the source of that leak.

Pictures as promised. I hope they help someone in the future.

I got that fantastic wiring diagram by Erdeniz Umman.

C63 depicts the ignition pulse generator as two coils. Even if they are really Hall-Effect sensors, it looks like it will be necessary to check for pulses on both #7 BLU/WHT and #8 WHT/YEL.

If you look close the pin out numbers should be there somewhere. On the plug or in the cavity if you unplug. It will be pin #8 WH/BL and will be just a volt or two DC. With a digital meter you will just get a blink. Analog on 0-5 volts will give you better needle sweep but for the most part it is there or not. You will have to check between pin #8 (PG) and common (pin #10) for one PG and pin #9 and pin #10 for the other PG. Check out Erd's color diagram. With the meter connected you should see the meter blink or the needle sweep depending on which meter you use. There are 2 PG's as you can see on the diagram. That is why you check between 9 and 10 also 8 and 10 while cranking the engine with the starter and the ECM unplugged. Might work plugged in but will work unplugged. The wires go from the ECM to the PG's under the plastic timing belt covers where the PG's live..

@DBohrer sent this, which corresponds to Erdeniz Umman's wiring diagram:


GL1500 ECM Wiring (1992 - 2000)

1. Yellow/red (Connects to an ignition coil)

2. Yellow/blue (Connects to an ignition coil)

3. Yellow/white (Connects to an ignition coil)

4. Black/white (Voltage from the Kill switch) Note: Also goes to all three ignition coils.

5. Green/black (Connects to the “intake air temperature sensor” and the “engine coolant
temperature sensor”) Ground wire...!

6. Green/white (Ground from the side stand switch)

7. White/blue (Connects to the ignition pulse generator) <<--

8..White/yellow (Connects to the ignition pulse generator) <<--

9. Pink/white (Connects to the engine coolant temperature sensor) Signal wire....!

10. Green/orange (Signal from the gear position sensor, 5th "OD” gear)

11. Light green/red (Signal from the gear position sensor, neutral position)

12. White/red (Signal from the gear position sensor, 3rd gear)

13. Red/white (Signal from the gear position sensor, 4th gear)

14. Green (Ground from the frame) <<--

15. Black/yellow (Signal from the gear position sensor, 2nd gear)

16. Red/white (Connects to the Carb air jet 2)

17 Red (Connects to the Carb air jet 3)

18. Gray (Connects to the intake air temperature sensor) Signal wire...!

19. Yellow/blue (Signal to the tachometer)

20. Black/red (Connects to the par solenoid valve)

21. Blue/black (Power “voltage” to the fuel pump)

22. White/black (Connects to the cruise control unit)


What I ended up doing with the information I had at the time, was proceed with the Pulse Generator Check (pic below)


I got open circuit (infinity) between both pulse gen wire pairs:



BLU & WHT/BLU (#7)
YEL & WHT/YEL (#8)


Following that wire leads to approximately where those pulse generators are, behind the front engine cover. My next challenge is getting that off without unnecessarily disconnecting too much stuff.


I was really hoping that simply removing that round, 3-bolt cover would give access to the pulse generators, but there's a disc that looks to have to do with crankshaft or belt timing, so I thought I'd better not loosen that until I find out more...

Have we confirmed there's no spark while cranking? If you have spark, the pulse generators are not your problem....

I know for sure that there's spark on at least the right side. There's a fuel leak problem on the left side, so I'll have to find the source of that leak anyway.
