testing with the voltmeter, on the battery terminals. what is the highest charging voltage you get while reving the motor?
I haven't tried that. I will give it a try this week and get back to you.
The battery seems to be charging well. What type of response would I be looking for and what would it indicate?
Ie...under 14volts might indicate...? Is this a way to tell if there is a short to ground?
Could this be why my winch, which is directly wired to the battery, only works intermittently?
Another note I should make is that I keep blowing the 30 amp control motor fuse. I have bridged the fuse temporarily because I kept going through fuses. I would assume that the shift control motor is drawing too much voltage, but it doesn't even actuate when I try and do the reinitialization process.
It's odd because sometimes the machine will find neutral, but as soon as I put it in gear it goes right back into limp mode.
Frustrating as all hell!
Ok, so I checked it tonight.
When idling without the lights on, it was registering at 16.9 volts. When I revved the machine it went up over 17.5 volts.
When the machine was idling with the lights on, it was registering about 14.0, but when I revved the machine it went over 15.5 volts.
So, now that we have proven your hunch, what do I need to replace now? Sounds like the voltage regulator which is right behind the ECM?
Here's my conundrum, if you are right on this, will the machine really work fine? Possibly right? Funny that the machine was throwing the 12blinks code, which seems to be completely erroneous at this point.
If this works, I certainly have NO PROBLEM paying you for your help.
Fingers are crossed, let me know what you think.
I'll get the part on order, install it, do the reinitialization, and if all is well, I'll certainly hit the ACCEPT button and get you paid. Might throw in a bonus too (if possible) if this is the fix FINALLY.
Thanks again - I'll be in touch shortly.
Sorry I've taken so long in getting back to you on this. I actually ordered the rectifier this week, and hope to have it installed this weekend. As soon as I get it installed and *crossing my fingers* if the issue is resolved, I'll be sure to hit ACCEPT and get the funds released.
Thanks for your patience.
FACCCKK.....still no good. The machine will not exit limp mode and code 12 is still flashing. I replaced the rectifier with a new one, still no dice.
I tried the initialization procedure, but it will not actuate the shift control motor. It just reverts back to code 12. I've had a few private messages from others who have this mysterious problem and have not solved it, having done the same things I have.
I tested the voltage when running again, and it ranges from 14.9-15.5 at idle, lights on/off, and when revving. Obviously the rectifier was a culprit.
I have a quote in ebay on another used ECM from a machine being parted out. Trying to save a few bucks given my past expenditures to get this machine running properly.
I'll touch base when I get it and get it installed.
You and me both ....haha.
I'll hopefully have it within 10 days, and it's easy to install. Man-o-man.....if it's not the ECM at this point, then I'm really stumped.
We'll see how it goes. I'll be in touch when I get it installed.
Hey Eric. Wow - too long since my last post. I just received the new ECM about a week or so ago, and installed it tonight.
Exact same symptoms as before. Goes right to 12 flashes. Cannot do the initialization procedure because it will not "find" Neutral.
Thoughts? I'm guessing I have 3 good ECM's at this juncture given that I have 3 and no symptoms have changed.
With the code 12, I verified all the wiring for the shift motor circuit. I've not verified any other wiring. Given that the machine seemed to not be able to find Neutral, I started looking for other options related to the shift positioning/switches. I found a recommendation on hondaatvforums.net which shows the switches and to test for continuity. I've not done that test yet, but I intend to this week for sure.
I don't know if you are able to manually reposition the shaft, or whatever the switches correpond with, to make the machine see Neutral again? I find it very interesting that I can get the machine to start the initialization, but as soon as the machine needs to show Neutral, it fails. Before that, I can start the machine, and now I have full Reverse and 1 speed forward. No gear selection shows up on the heads-up display though.....
Any recommendation you may have, I'll do my best to perform.
Do you have recommendations on what tests to perform with a multimeter?
