I doubt your battery is the issue if your voltage readings are correct. Did you try initializing the system yet?

I actually had three. I bought one for my oldest kid (that 300 that Shade did the engine on), which is currently mounted on her 300. Had one for the big 300 I planned on building until my 29.5 Outlaws got stolen. I traded for those tires, and at that time SamUK was going to build me a GR, so I wouldn't have a lot in it, but tires got stolen, and SamUK disappeared, so I don't see myself ever spending $1K on tires, and another $500+ for a GR to have a big slow moving toy, so I doubt that machine ever happens. And then I have the little one who is almost 5. She'll get a 300 when she's older, so the last one is for her So i had plans for all 3. Big bike for me is unlikely to happen, other two are for kid's machines. MSRP on them was $369. I had two new ones and one used one that I put new bearings and seals in. Sold one new one, other new one is on the eldest's 300, and the used one will go in the little bit's bike.

Welcome aboard. Does it drive in auto mode? You need a good strong battery on these for them to work right. If you have a good battery on the machine, try initializing the system. Machine in neutral Hold up and down shift buttons in and turn key to on position Hit up, down, up on the shift buttons, then open and close the throttle within 5 seconds. That should re-initialize all the computer crap. See if that changes anything.

I don't think the valves really have anything to do with the mechanical aspect of the shifting. They divert oil pressure to the dual clutches. Is that correct @toodeep? (otherwise I'd tell you to remove the valve and see if it will shift with the valve not in place, but I don't want you to do unnecessary work and i think toodeep has more experience with these than I do)

I figure with what they're bringing now that someone will start making them again eventually. Money got tight last month and I think my ideas of building a big 300 one day will probably never happen so I listed mine and quickly sold it. Got me through the month and I still have a used one in the drawer for the 300 I'll do for the little one when she's older.

Honda made a hydrostatic 4wheeler. You should get one!

Video above worked for me. Looks like error code 4, which isn't in the FSM. You have any ideas?

Have a smartphone? Can you take a video of the flashing and post it up?

Welcome aboard. If you go to the "service manuals" at the top of the page, click the links to download the service manual. Section 4-8 and 4-9 have the error codes. There is no code 4, but there is a code 44. Is your cooling fan on as well?

I had a new 2nd/3rd gen I sold a couple of weeks ago for $800. Buyer was willing to pay $900, but I'd had it listed at $800 so I honored the ad (he offered extra for me to ship it). Sold it pretty quickly. I think the guy that mods those to fit a 1st gen charges a couple of hundred bucks minimum to do it, so this really isn't a bad deal if you really want one.

That's pretty cool. Reminds me of the truck in The Road Warrior with that front bumper.

So, this might be a stupid question, but I’m starting to think I have burned/melted wires in the harness somewhere. Is that what you electrical experts are leaning towards? I’m eyeing this https://www.ebay.com/itm/256307769169 Since the CKP test looked ok, safe to say the problem should be in the harness/ECU?

Pretty sure that one is toast. I’ll let @AKATV chime in though. The good thing is, new Rincon meters are still available from Honda.

I wasn’t much help, but thank you for posting the fix! Should help someone out in the future

I bought some 300 gaskets from them. They are not OEM but were good gaskets. I still need to call you back. Had a day from ! at work yesterday and I’ve been driving all day today headed to the in-laws for spring break.

So, zooming in on this pic on my computer at work, much easier to see. You see the yellow/blue wire that I spliced using one of those heat shrink tubes with solder in the center. That was a wire that was completely gnawed in two by a rat, which is why the wheeler was originally brought to me. I fixed three such wires, wheeler ran, and I returned it to the woman. A couple of weeks later she called me back, wheeler was dead again. I discovered blown ignition fuse, and when I replaced the fuse, the coil smoked and hissed, and I realized the coil wire had melted to and was shorted on the exhaust. I have not found any more wires gnawed in two, and the woman moved the wheeler from a barn to her carport when I returned it to her the first time. So should I snip. strip, and reconnect the wires that were gnawed but not broken to make sure they have a good connection? Replace the whole harness?

Yep, that's exactly the problem I found on the 500 I linked to above. I'd check that. Not a terrible job to look under the front cover since you don't have to pull the engine.

Misery loves company......

I see what you’re talking about now. Green wire gnawed on. Am I better off snipping those and stripping them back and getting a better connection? i’m fairly certain that the rat damage was done before the coil wire melted

That was the initial problem was rat chewed wires. I used some of those heat shrink connections with solder in the middle to put the wires back together. Machine ran until the aftermarket coil wire melted on the exhaust.

No voltage at the coil with that gray plug disconnected. Plugged it back in and coil reads 10.95 V battery reads 12.33v So are y’all thinking this is my problem?

Yeah, that's my buddy's that I borrowed last week to try on that Foreman I'm working on. I took pics of the wires to makes sure I put it back the way it was supposed to be.

Green wire on green tab.
