Welcome to GC. I'm horrible with electrical, but this will bump you to the top. I would suggest starting a new thread with a more specific title related to your issue, as lots of guys will not bother to look at all the introduction threads that are started here.

 

Hello and welcome!

 

Welcome from Oklahoma. Someone will be able to help you.

 

Welcome from Colorado.
Can you bug out the electrical yourself? I don't like screwing with electrical either, but;
Start it and watch the power in and out of the relay. The relay could be intermittent power continues in but stops coming out.

 

Hey..bluecollar1...Welcome to GC from Wisconsin.
Let's start with more info.
Is the kill switch in the run position?
Does the engine turn over with the battery?
Does the battery have around 12.4 volts with ignition and lights off?
Did you try to pull start it with the recoil?
Did you try a brand new spark plug?

 

Iwill check all the above and let you know

 

Sounds like a bad part affected by heat to me. With electricity, the more amps you carry, the more heat you make (why wire is sized for amperage, not voltage or power(watts)), and the more heat you make, the less amps the wire/part will carry. It sounds like you have a part on it's last leg that's unable to carry enough power after it gets hot to create an ignition spark.

As to what part that is, you'll have to rely on another person here, as I have little experience with Grizzlies (can't seem to break anything on mine ). I'm sure these guys and gals will get you there as cheap as possible in the end though. Go GC!!!

The other poster mentioning a specific thread is right as well. More eyes that may be able to help you will see it if you do that. Good luck and have fun when it runs! hehe

 

03 660 grizzly will not start (no spark)

A little info to get started. The quad was running great, never had any problems with it, other than a solenoid. Four days ago it just stopped no warnings of any kind. Got it home tried it again no go. Next morning tried it started right up. Ran for about 3 minutes and died. would not start the rest of the day. Next morning gave it a shot and it started right up. Ran for about 1 minute. Nothing all day. Tried next morning nothing. At first I though maybe fuel,was 30 below. I added some gas line antifreeze after the first day. Took the plug out check for spark. nothing. Replaced the plug nothing. Next thing need to check the coil (does anyone know how to check a coil) need help. I also would like check the stator (again need some tips on how to check the :icon_ laughup:.

Does "would not start" mean it will not crank or will crank but not fire?

 

Thanks I will go through the list and let you know how I make out.

 

I've been diagnosing a no spark issue on my kids 90cc quad. It should be a similar test procedure for the stator. If the bike wont run anymore, unplug it (the stator). There should be 5 wires coming out of it (engine case). 3 of them (usually on a single plug) make up a 3phase generator. Those three wires are the A, B and C phases. You need to test the resistance (ohms) on each combination of those wires. A-B, B-C, and A-C. They should all have the same value or very close. Next, test each of those wires to ground. If any of them are grounded, there's a short in there and it needs rebuilt or replaced. If the bike does run, you can test the output voltage in ac. Probably somewhere around 35-40 volts at idle, and climbs when you rev it up.

For the coil, it's sort of a test, but not very conclusive. Test the resistance of the primary and secondary circuits. I don't know what the values are, but they are probably posted online here somewhere. Basically, you're just looking to make sure there is continuity here. To test if there is another problem of grounding (this is how the coil is turned off) in the system, you can pull the ground wire off the coil and try to run it. This should bypass any on/off switches in the system. I don't know what style of coil is on the Grizzly, but some of them ground to the frame and a wire, so you might have to remove it from the chassis to do this.

There is a rectifier in the system to convert the AC voltage to DC. If you have good AC power going into it, but not 14.4 DC coming out, it's suspect.


Start there and report back.

EDIT: For what it's worth, my kids stator tested bad. two of the phases tested 6 ohms, one would only go up to 4. That test is almost okay. But for the ground test, all three phase wires were grounded on ours.

 

Ignition Coil Test

Pickup coil test

You should get a service manual.:happy:

 

Hey..30..Long time no hear from you. How you been?
Did your house fall in when you installed that door in the basement? As the over zealous carpenters touted!:devil:

Okay back on subject.

Hard to test a coil if you don't know the values.
I would guess a guy could search them out.

 

Been doing alright, thanks. Didn't think anybody knew me around here, lol. I read the forums a lot, but don't necessarily post much.

Basement door has been awesome. I can get the grizzlies in here if need be, but works great for moving anything in and out. No cracks in any drywall yet, and I haven't burned the place down yet either.

 

Welcome to GC.

 

Thank you much for this info. I will be working on this problem this weekend. I am ordering a service manual today. My problem is download speed. Manual is quite large. Will see how it works out. Again I appreciate this.

 

I've seeing many posts with a worthless title lately.

Here is a little explanation of the need for a good title. credit to our friend "idig..."

"in the future... on this and any forum... try getting a bit more descriptive with your title. it is there for a reason. many reasons actually. its great for people in the future that have a similar problem. they can search and find info easier. its great for the advice givers cause when we get notifications of a response, we know what it was about. its also nice for people browsing the forum cause they know if they are interested in learning about the topic, or interested in giving advice on the topic. seeing a post titled "problem" gives absolutely zero info to anyone browsing, searching, or responding to the topic."

Agreed, but in his defense, it does sound like a short has been introduced. :nana:

 

The bike turns over well, no spark

 

Do you have a meter so you can test the pickup coil and the ignition coil?

I'm thinking it is the pickup coil. On my 660 it went out over a period of a week or two.

 

Yes I have a test meter. I printed the info on how to test the coils. Will do the checks this weekend

 

:rocker:
Also look over the wires. They like to fray just outside the crankcase.

Good Luck.

 

I had a similar problem on a old Skidoo. Would run perfect until it got warmed up nicely than would die. It would take about 10mins before it started again. I replaced both coils (twin) and all was good.

 

Welcome aboard!
