  1. I've read alot his posts. He's a sorcerer with these things lol
  2. The later model (02 up) has selectable 4wd which also adds a light in the CM. Akatv would be able to elaborate more than I ever could
  3. Still gotta bleed the brakes and fix other small things. Got all the plastics on today
  4. Well I bought the bike apart from a friend. Came with both ecus. I was told one is new. One is oe. The new one is just a goner I suppose. These used one I have is the only good one. So now I'm just going to put it together and get it in good shape. And ride it. It's got 1344 miles on the clock and 288 hours
  5. So bought a used ecu on ebay. I chose used cause it would be a known good unit, and it was cheaper. Mostly wanted for the known good part. The oem one must have been shot. And the new oem one must have been shot, out of the box. This used ecu I got, not only do I hear the relay click with key on, it also shifts. The battery might be weak. But I get a shift. With niether previous ecus did I get a relay click from the ecu with key on. Getting there I suppose
  6. There is 5v voltage to and from handlebar up and down switches Cleaned ground on frame Changed connections at battery (for no reason just hopes and dreams) Bought a ecu on ebay, waiting on that Jumped the pins from the ecu 5 wire plug and the motor did shift gears
  7. The brand was elysis or something like that. And Rocky mountain site shows that as honda manufactured. Either way I'm going to try and find an ecu cause I don't trust either of them. And if the ecu still don't work then I know it's still a wiring gremlin
  8. So here's what I've done, that I remember to date Put known working shifter controls in. Quad had controls taken apart and missing pieces to find shifting issue. I verified that these new to me controls do work, and have continuity when buttons depressed. Also jumped the pinouts in the connector to bypass the controls, still nothing. Black orange to either wire Followed diag for wiring in honda manual. Checked most if not all wires that work with the es system. Only wire I found that wasn't right was the grey black wire going to CM. No continuity with ground with the plug connected, key on, and in nuetral Speed sensor tested. Has correct input voltage. And reference wire outputs 5v and speed is recorded on CM Replaced rectifier with known good rectifier Replaced angle sensor with new oem honda sensor. Original tested good ES shift motor spins with 12v, and has been cleaned inside no damage All connectors in harness are dry, with absolutely no dirt inside. Also checked over the whole harness for damage, or wire pinches Swapped ecus. One ecu is oem original. Another is Rocky mountain new oem. Both 771 codes. The old one has a steady neutral light. The new one has a flashing constantly neutral light. No codes. And no codes are retrievable. The time on the CM resets after about a day even though the battery is being maintained at 13v+ constantly Edit: I found this to be wrong. I unplugged the CM about every day because I work on it every day. Killing the saved time. Swapped batteries with known good battery Tested all the fuses. They all tested good but I replaced them all anyways. Gear position sensor records every gear on the CM and tests out good as well Checked and verified grounds and battery connections Voltage to ecu is battery standard voltage. The only things that stand out to me is that the grey black in the CM doesn't have continuity to ground. They both have to do with the CM and I have not been able to swap that out yet, being I don't have one available. Akatv you mentioned these two things before. Edit. Grounded the grey black wire just now and I hear a click from the ecu and the gear indicator goes blank. So I'm assuming now that I have a bad CM
  9. Might be late now but I'm about to work on it if you're around
  10. Any other takers. Might work on it tonight
  11. Also the time resets about daily and its on a charger
  12. No continuity on Grey black key on in neutral. With harness plugged in and all
  13. Will do. Hopefully it checks out. If not you might be getting a little business from me
  14. Ah ok yeah that makes sense. And also makes sense of the "key on in neutral" part. I'll back probe the meter in a bit I'm actually picking up a couple parts for it now
  15. Yes but what's weird about that is if the meter is unplugged from the harness there is no ground connected so it will not have continuity to ground. The ground from what I'm seeing is in the harness
  16. See this is the information I'm looking for!! Ok so I did check, continuity from ecu to Grey plug is good. Grey plug on meter side, to ground is none. So the question is, I read that the meter is not essential to quad function and is only a display. However I don't believe that because the manual wouldn't include meter testing in the ts section for ES if it didn't matter. However now that I think about it. If the plug is undone for the meter, and the ground for the meter is in the plug. How would it connect to ground lol. I'm likely doing this wrong as it doesn't make sense. Do you leave the meter plug connected to the ecu with key on and then test via probing or?
  17. I've done all that already 😅😅 I have two ecus. A new one that flashes the neutral light constantly with no stop, or the old one that the neutral light is steady on no flash. Niether gives a code. And both are oem. The video went over a few things. I have known good shifter switch controls, I tested them as well. I bought a brand new oem angle sensor, even though the old one tested fine. The speed sensor is original, but it also tested fine. 5v+ when 4wd tires are moving and the speed registered on the dash. I have a known good rectifier coming, which probably won't help because the charging system doesn't affect the ecu I don't think, if the bike is off. The only abnormality I'm seeing is that the combination meter Grey black wire does not have continuity with ground. Do any of you think you can test yours for me? I doubt your bikes are apart but if for some reason someone had a combination meter laying around they can try it
  18. On the ecu side of the red yellow wire I'm getti g battery voltage. The black blue wire on the other side eof the ecu that goes to ignition is 1 volt power than battery voltage, 12.5. I've also been keeping it on trickle charge
  19. So I have an 02 450es. I've spent probably close to 10 hours diagnosing and checking connections all to find nothing leading to the shifting issue I'm having. It will not power the shifter motor. There's no codes. And if I go to retrieve them, it still says no codes. No flashes nothing. I've tested the motor with 12v. Did almost every diagnostic in the manual for the es shift. I have a spare ecu for it I tried but when that one is plugged in, the gear indicator flashes constantly with no stop. So I took it out put oem in. And it stays solid neutral. I can shift gears manually no problem. I took the shifter motor off, the grease is bad whatever. But the motor itself still isn't actuating. I've checked just about all the connections. They are all brand new inside. The handlebar controls ohm out with button pressing. Gear position indicator works. I have a rectifier coming, angle sensor coming, and had a ecu coming before the guy broke it getting it off the harness. But if he will send me the cracked ecu I will test it. I've taken the motor apart, used a scotchbrite pad on it lightly to clean up the contacts and put it together the motor runs. But something is keeping it from getting computer power. I think it's either the ecu or the dash. The computer doesn't actually know there is something wrong, it's an 02, 02s throw codes. This one has none and is dead in the water. Runs. But no shift. I put in a new honda angle sensor. I've checked over the harness for cuts there's nothing. I haven't cut open the casing, only in one part by the grounds by the stem. I tried a different battery.
  20. This is electric shift selectable 4 wheel and there's a tool for the shifter on bottom of left side case
  21. Ok that clears that up. This is an fe then. I'm having trouble finding people that know these things inside and out. If you don't mind I'll copy and past my whole biography of this thing of what I've done maybe someone can help me
