Hi guys and girls. John Talley here with Partzilla.com. What we're gonna be
looking at today is a potential no start scenario with our 2007 Honda TRX 400 EX.
Alright so you're getting ready to go ride Saturday. You walk outside, turn your
key on, hit your start button and nothing happens. Alright as we can see there's no
light on, that indicates or neutral indication light. Wouldn't even come on.
So something systemic is going on here. What do we need to look at? Well the
first thing we need to look at is the battery voltage. Let's take a look at it
and make sure it's okay.
Alright, so we set our meter to DC, hook up our ground. Let's take a quick peek in
there. Twelve point eight seven. I'd say that's good so the problem must
lie somewhere else. Alright, the next place you need to look, particularly on
this model, is this little junction right here because that has a main fuse that
operates the entire machine. So let's pull that cover off and lookie there:
looks like somebody put in a incorrect fuse. That should have a 15 in it. Guess
what? You can see right there that the filament is blown. So that is our culprit.
Honda is nice enough to send us an extra one, It's just a one right in front of
where the main fuse sits. Pop that back in place, and I'm betting she'll start up
now. Light is on, hit our start button. There you go. Okay as far as diagnosing
something, they can get much simpler than that. Let's say you replaced, or your fuse
was okay and it still didn't want to start. Where would you need to go next?
Alright what I would probably look at first will be this solenoid down here.
Because if you've got a green light up top, and you're hitting your start button
and nothing's happening? That isn't getting activated. So what you can do to
test it right at the battery. Disconnect it from the the main vehicle
harness. And with just one jumper, you want to go with the yellow and the green
stripe over to your negative with the machine turned off.
Take the yellow with the red stripe and just touch it to your positive and
what that's going to do is just turn the engine over. So guess what?
That solenoid is working correctly as well as the starter. But let's go one
step further. Let's say that you hit it and you heard the solenoid click, but it
didn't turn over. And the click that you're going to be listening for is
sounds like this. I just happen to have a brand new one which we're going to do
the same thing we just did with the one that was mounted on the machine you're
gonna hear it click. Hear that? What that's doing is actually pulling up
a set of contacts that's making these two points come together inside of that.
So if you heard it click and it still didn't turn over the starter, that
probably means you have a bad starter. Listen this is just a few tricks of the
trade into where you can quickly diagnose a no start condition. As you're
going through it, if you find out that you need the starter solenoid or the
starter itself, Honda is nice enough to send another fuse so at least thought
would get you back on the trail. But I would advise you to go and replace it
because you may need that replacement at some point in time. Well listen, if you
need any of these parts, please come see us at Partzilla.com. And if you have any
questions or comments? Having a little bit of trouble figuring out your own
machine? Leave them leave them down below and I'll do my best to answer them and
guide you through this process. Listen we appreciate you watching and we'll see
you next time. Thanks
