Hello, John Talley here with Partzilla.com.
We're doing a little work on our 2007 Yamaha Grizzly and I want to ask you a question:
every had one that wouldn't turn off?
Well, that's what's going on here.
So, let's head over to the tool bench, talk about some tools and maybe some parts that
we're going to need to figure this out.
So let's go.
Welcome to the tool bench.
Now typically, I can tell you exactly what tools you're going to need to do a project.
Well, we're in a little bit of uncharted territory here.
So let's just start with the basics.
Get a Phillips, a test light, and a good volt-ohm meter.
What is more important is to look at our exploded diagrams.
That's going to show you where each different electrical piece is located on the machine.
So, I really don't know what parts to tell you yet, but at the end of the video, whatever
we choose will be in the description at the bottom of the page.
So, once you've got your tools and your diagrams, we can go over there and try to pick this
apart, so let's go.
Listen, I've replaced the battery on this thing, after I've cleaned it up and I may
have done a little too good of a job cleaning it up, because turn the switch off, and it
is still live.
So, we need to figure out what in the world is going on here.
I can hear a relay clicking over on this side, so we need to go find out which relay it is
and what's triggering it.
Instead of fixing a problem, we've created one.
It happens, but we're going to figure it out.
When you're trying to diagnose a problem like this, I usually like going straight to the
heart.
So I want to look at the ECU first because that is the brain for the whole machine.
Now we want to check this because it could have water intrusion if the seal failed.
And if water got into there?
That could be causing what we're seeing right now.
So let's start there, make sure it's okay.
We want to make sure that seal is still dry, all of the connections are dry, and then it's
good to go.
I don't think there's any water intrusion in it.
The connection is dry , the seal looks like it's good to go, but our display is still
on.
So something in there is still getting triggered.
Let's just plug it back in and actually I want to look at the physical switch and then
the associated cable that's coming back to the ECU.
I think we may find something there.
This also may explain why the battery was getting drained, because I'm feeling the wiring
that goes from the actual switch to this connector right here and it's actually warm.
So, betting there may be a problem in there.
So, let's disconnect this, then actually pull the switch and we'll see what's going on in
there.
Given the amount of creative wiring that I've seen so far, I think somebody actually tapped
into that wire coming from the switch directly is causing us a problem.
Right there, that's where I felt it getting hot.
I'd say those wires are definitely touching together.
So, let's open that up.
What a mess.
Yeah, I don't think we're going to be reusing this particular switch.
That is a mess.
Well, there's your problem.
That would be why it was not wanting to shut off.
That is only a half a step away from maybe catching your unit on fire.
So, we've got it completely unwrapped, and well, that's kinda the problem.
It shouldn't be wrapped.
This should be a continuous sheath that encapsulated the wires.
Evidently the owner went in there, stripped it back, made some type of connection for
who knows what-- stereo system, a set of lights, I don't know, but that was a big mistake.
And he went and pulled the cabling out because it was not present on the machine and just
wrapped the wires back together.
Well guess what?
That left them exposed.
Eventually they were rubbing together, they started to burn, and when I actually pressure
washed it, I got some water down that wire, it started making a connection, turning our
display-- our machine-- on and off.
So, this is an example of what not to do.
If you're going to buy a used machine, ask the owner did you have any accessories on
it that you took off because that's what caused this problem.
One, it was installed incorrectly, whatever the accessory was, and when he stripped it
out, he didn't do it properly.
And that right there?
You could have lost your unit over it.
So guess what?
I'll be heading back to Partzilla.com and ordering a new switch for our unit.
Alright guys, we've got our new switch with the new key, and I can tell you when pulled
the old one out it was a little too tight in between the fender and this little storage
container.
So we're going to remove it and make it a little easier to reinstall.
Just have a couple of Phillips, and there's I guess you'd call it snap ring kind of design
that holds it in place.
Get both of those out.
That ring is actually split.
Just need to get it out of the channel, like that.
And then feed it around.
There we go.
Just drops straight down.
Now we've got a clear path.
Just make sure this protrusion right here lines up with this notch on the plastic.
There it is.
When you go to snug this down, don't get carried away because we're talking about plastic threads
here.
Doesn't take but a little bit to hold it.
Now we can just feed it straight up through.
There she goes.
Connect it.
Get the wires back in that channel.
Now we can get our little dry storage container back in place.
Get this back in the groove.
We'll do one side, push it in, and get the other side done.
Alright guys, we've got our switch installed, let's make sure it turns on, which it does.
And most importantly, is make sure she'll turn back off.
There we go, now I think we've got something.
Let's get that ECU put back in place.
Just a reverse of what you did to take it out.
And remount the regulator-rectifier.
If you're still having problems with your machine, we have a video that really drills
down into the starting system on this particular machine.
Well listen, if you need any parts, why don't you come see us at Partzilla.com and we can
get you taken care of.
If you like what you see, why don't you go ahead and hit that subscribe button, that
way you can keep up with whatever I'm working on next.
We just want to say thank you for shopping with us at Partzilla and we will see you in
the next video.
Have a great day.
