i did not make you buy anything, I TOLD YOU..BEFORE YOU BUY PARTS ?..GIVE THE WIRE HARNESS A GOOD INSPECTION..DID I NOT ?..LOL. 

You did... and I'm just kidding with ya lol

i'm going to pm you.

He's a stand up guy! He was really good helping me.. & I definitely appreciate it..like I said before if it wasn't for him I would have probably gave up on it! 

I posted the problem on shadetrees post. He had me to put the old stator back in and there was a bad wire in the harness ( stator ) harness. I posted it there because I see so many people not come back and post the problem to help someone else. Thanks again for all the help. If not for Shadetree I would have gave up on it lol..

You’ll find it no doubt. Then you’ll have some hard-to-find spare modules 

 

You have aftermarket fuel pump on it?

 

the coil may have color codes on the housing. The important thing about a coil is you have primary and secondary windings. The secondary has more windings (usually) and so the resistance values are different.
 

So if you can’t tell the poles apart. Consult the service manual on coil measurements and put the meter to it.
This is why Fish said to remove the coil spark plug cap. Then you inspect the spark plug wire for corrosion and nip off a bit. Then clean the spike end of the cap with a .22 cal bore brush

Got it fixed thanks so much!!

fuel relay gets its power signal from the pick up coil. this is why the fuel pump only pumps when the engine is being cranked over.

I tried, has voltage going to fuel pump relay.  Won't pump when spinning over .. a guy had a 2000 honda fourtrax cdi box .. plugged it in.. heard fuel pump or relay click and with that cdi box the fuel pump works.. still no spark though. Thanks!

Yes fan comes on when grounded. 

True, already have one and it's installed

I do have a after market fuel pump on it, which hasn't been working unless you put power to it with a probe. Odd enough a friend had a cdi box off of a late 90s honda. I plugged it in a heard the fuel pump click on! And it pumps or pulses when spinning it over. Still no spark though.  Btw missed fishes post but have tried 4 or 5 coils 2 I knew was working 3  new aftermarket that is in specs. Thanks!!

you lie !..lol. i spoke to him on the phone..soo..take that !...lol.

Still waiting on parts.. be in touch when they come in and get it on.

At least you’re learning the ignition system!!  Are you gettin a new pulse generator? 
 

While waiting for parts, continue to inspect and perform electrical checks on wires you may have jostled while doing your other repair work. Use the schematic to double check the kill switch at all those connections on the right front of the quad.
 

get some contact cleaner, permatex dielectric grease and a few plumbers flux brushes. Maybe a brass and nylon gun cleaning brushes. not steel brush. Disconnect and clean all those connections while you’re doing continuity checks—apply a thin film of the grease on the electrical contacts and the backshell of the connectors—you’ll find they snap together and disconnect more easily.

 

Look for weak wires on the harness and subharness. every time i went to start mine i had a steady neutral light. When i cranked it the light would go out. So I swapped the neutral and reverse leads and tried again. Of course the reverse light came on steady and i got it to start—that was a hallelujah moment, because i knew the malfunction was isolated to the neutral wire portion of the circuit. i found the neutral switch connector wire hanging by 2-3 strands. 

 

Does your fan come on? Disconnect the oil temp sensor lead and touch it to the footpeg. The oil light should come on steady and fan should come on 
 

 

Yes fan comes on when grounded.

for the record, i've been doing this 30 yrs..i know these models inside out...there ain't much about them i do not know ?!..lol.

I've never doubted you're not qualified, it's me I'm doubting lol

I don’t think you answered my question about the pulse generator. When you measured resistance at the pulse generator did you measure it at the leads under the right side cover? That’s the shortest length of wire through the unit. 
if that’s when you got 400 ohms that’s out

Sorry I missed your question, yes that where I measured it at .. 400 ohm.. spinning it over and measuring it comes down to 360

Thanks for clearing up that he has correct CDI; the other thing i want to clear up is that the 87 TRX350D is the one-year only CDI.

 

also @Raystrx350d when you “probe the fan lead with 12vdc,” that’s not the same as what i recommended. In the manual “oil cooling system diagnostics” the exact method is to remove the lead as @shadetree said and touch it to the footpeg. This closes the oil temp sensor circuit thru the fan control unit, which energizes the fan circuit.

 

Being inexperienced at troubleshooting, you’re still trying to understand component nomenclature, principles of operation, troubleshooting techniques and the problems with aftermarket parts. Don’t give up just yet. Rely on the manual—read the troubleshooting guides.
 

Also i would not use probes that pierce the wire sheath; is that what you’re using? 

I did ground the oil temp light and the fan did come on... thanks!!

sorry, you do have the correct cd.i.

Thought so... still at a loss.

the part number i posted above ^^^^^^..that is straight off rmatv, which only sells oem honda, and that part number is for a 1988 trx350D only !!!!.

That part # is for the rubber piece that holds the cdi... 

Just now, Raystrx350d said:

I'll check them out, thanks 

What's the website name? Thanks again

wrong c.d.i. !.

Well I thought it would be the same with the C1545 on it...honda says this is the part number for i🤷‍♂️

here is the part number that should be on the box ----> 30401-HA7-670 , if it does not have his part number on the box ?, then you got the wrong c.d.i.

Doesn't match your part number, I included pictures of old and new cdi and part number
