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?

The coil has to be bolted down too.

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.

Green on a Honda is almost always ground.  On the coil, the black/red wire is + and the green wire is -

Well the only one of these I've torn down was about 10 years ago, and I honestly don't remember. 

I am fairly certain the front cover comes off, then there are a couple of more bolts holding the spacer on, but I can't be certain of that.

Sounds similar to what I have going on with the 2013 Foreman with no spark. (which is pretty much a 420 with a bigger jug on it)

you got that shaft ?, i bet i know where you can find one !..lol. as for the rings ?, a simple ebay search will locate aftermarket rings, been there..done that. you can get the whole cylinder, topend gaskets, rings, piston ( aftermarket ) to fit this atv. yes..i know its china aftermarket ?!. but when it comes to old parts that are no longer around ?, you have no choice but to bite the bullet, and do what ya gotta do to make it work.

Well this is @basfnb's, so I ordered one off of ebay.   I have two of these in the yard, but didn't want to tear down an engine for a $30 part (got the whole input shaft with all the gears).

And the afternarket cylinders, pistons, rings, etc have all dried up for these!  Hopefully it's temporary, but it's all unavailable now!   Nuts!  Gaskets are no problem, but the others bits are unobtainium.

#19 is the shaft, I can turn the shaft each way and is spring loaded both ways but no shift, so maybe it's not connecting to the forks maybe? I ordered a Service manual yesterday to see how the forks connect with the shaft. No video for this model that I could find.

You can download the factory service manual free in the toolbar at the top of the forum.  It's under "Service Manuals" button. 

This is a 2016, shows some details on what's under the front cover starting at about the 2 min mark.   The 420's really haven't changed over the years.

So # 19 in this schematic?

My guess is either #18 is broken, or the spring fingers are not straddling it.  Unfortunately no way to know without pulling the front cover.

So I should have all forward gears, correct? It should start in any gear?

 

The neutral mod just bypasses the switch and not allowing it to go into reverse?  because it can't actually get into neutral.....

 

Are there any cable adjustments to make for reverse? The cable at the bottom of the engine.  How about the clutch adjustment nut on the front?

You should be able to shift gears with the machine off.  If you can’t you probably have problems with the shift linkage under the front engine cover.

Lets look into that first. 
 

If you’re stuck in gear my guess is it is something similar to this

Welcome aboard.  
 

Is it an FA (auto/ ES with independent rear suspension) or a 420 FE (ES, or manual electric shift on handlebar)?

Found the shifting problem.

Spinning the transmission on the bench was catching in either direction.

Transmission gear on the input side of the transmission.

@rich250rracer you having any luck?  
 

I’m still in the same boat with this 2013 Foreman that has no spark.

this is what you get for working on those stupid 500's !..lol.

My old air cooled, carb’d Foremans are easy to work on!  This EFI “bigger 420” is giving me fits!

 Everything else plugged in or ?

Unplug the green connector (14pin)  going to the display meter --see if voltage goes up

Did not.  No change.  (Well

it went up like 2/100’s)

I personally have only ever used bed liner on my rims to date.

Well, started breaking down tires again today. I said I wouldn’t do it again, but here I am. As I posted in the tire section, I found a set of 25x8x12 and 25x10x12 Bridgestone dirt hooks, in like new condition. Of course I now have stock rims, 12 in front and 11 in rear. I broke down the front 2 wheels and got one tire mounted, but of course I’m having trouble getting the bead to seat yet again. I got the other side broke down and pulled the tube out, but I have to put a new valve stem in before I can mount that tire.

 

For the rear, I’ve got a set of 12” rims but they’re at my dad’s house in SC, so it’ll be Saturday before I can get them. I’ll have to break down the Titan 589’s on them and then mount the dirt hooks. The rims I’m getting are painted black, and I would like to paint them the factory silver to match the front wheels I have now. Does anyone know what color that is exactly? Silver? Grey? 

 

While I’ve got the rear wheels off, I’ll pull the axle apart and pack the bearings. Hopefully that’s the last time I’ll have to take the rear apart for a while.
 

 

 

 

I think maybe @_Wilson_™ or @Wheeler painted wheels silver and found the right color?

I don't envy you having to break down some 589's.  Those tires have some STIFF sidewall/beads.

I found @shadetree's method of smearing grease on the beads to work well for most bead leaks.   I rub the beads down good with steel wool, then smear a thick gob of grease all the way around.

Thanks for reporting back!   Glad to see it worked out for you!

I’m out of daylight here. I’ll see what that does in the AM.  Gotta get the mini-me to bed

Can stick a pin or something sharp into the Bl/R wire at the fuse block to take a reading

yes sir.  I did that.  On the battery side I get full voltage.  When I put a fuse in I get a voltage drop across the fuse.  Tried multiple fuses.  Something is drawing it down

I did check and clean the grounds per @retro as well

Thank you for your help!  This one is a bugger.  All from using an aftermarket coil.

Could you check the voltage on the BL/R wire on the fuel injector

11.53 with my voltmeter negative probe on the battery. 11.22 with the negative voltmeter lead on the green wire on the injector plug
