Coleman Product Selection Issue

[trinityspeedwash]

Another newbie question. I have a product labeled "Tire Cleaner" that is supposed to be "low pressure" from the "high pressure" wand. When this selection is engaged, across any of the bays, the high-pressure wand only spews out a little bit of air.

I have attached some pictures/videos.
The product bay for the tire cleaner appears to be bubbling (video).
The product air control shows 50 PSI on the intake, but nothing on the output dial.

Note that I have tried adjusting the output valve, but this does not appear to do anything .

Does anyone have a recommendation on what to try to nail down first as the issue?

Thanks as always.

Can you hear the tire clean pump run? If so try decreasing the air down to 10 psi or so and see if it will pick up and start pumping again. If this works you can increase the pump pressure on the pump. I run mine around 70psi but many people run lower. Whatever your choice the air should be about 15psi lower than the liquid pressure. If none of this works but you can still hear the motor running you may need to replace the pump


If the pump is not running you could have a couple of things wrong :Bad pump, bad motor, or bad or stuck float switch in the tank that has cut the pump off. Also could be a bad IDX MX controller. Check the float switch first obviously

Thanks. Just to confirm, this product would have its own pump? I am thinking that since this is “low pressure” it would run off of city water pressure?

Is that a thing?

You posted a picture of the tire clean manifold. Just below connected to the gray line is a motor with a small procon or roto-flow pump attached. You foam brush, tire clean, and foaming conditioner use that setup.

I am making progress at diagnosing this. The motor with the roto-flow does not turn on when "Tire Cleaner" is selected. What is the best way to diagnose why this is the case?

Should I hook up a multi-meter to the motor power cables and see if it shows any power?

I have also posted a couple pictures from my multi-plexor for the tire cleaner, but I am not sure where I should check next for the power for the pump motor. These pictures are when I go to my Bay 2 and I select "Tire Cleaner".

Any feedback is appreciated.

Check terminal 3 on the MX controller for incoming voltage and check 4 when the tire cleaner is on for outgoing voltage. If you get voltage to ground the controller is good

I've got an old super saver system and on mine it leaves the controller and goes to a relay with a float switch acting as a control. From there it heads to the motor.

I have finally made some progress on this.

- Figured out that product was not coming out.
- Replaced the product pressure regular.

Now when I fire up the pump, the product comes out (good news) - however, after a couple of times, the fuse will pop. Picture attached below.

Is a popping fuse the sign of the motor going bad?

FWIW, it looks to be a 5A fuse that I use here.

Im pretty sure the fuse is a 10 amp. I will check tomorrow when im on site. 5 amps is for the meter boxes but the 1/3 HP single phase motors for FB,TC, and TF FLA is 7.2 amps. The bubbling in your tank is because your product was not working so the air was pushing back taking the path of least resistance.

 

[trinityspeedwash]

10 amp fuse? So perhaps the issue is that I am reloading it with a 5amp fuse instead?

Yes. 5 amps is not enough.

 

[trinityspeedwash]

It continues. I replaced the fuse, but I think the problem is with my solenoids.

That is, I can now see pressure build up on the gauge when the pump runs - which is good. However, I don't have any product coming out the solenoids. (I only tested two).

The good news is that the multi-meter shows 24V when the bay is set to the product, so I am getting power. I am wondering if the solenoid is "stuck" since it hasn't been used for a while/is old.

Anyone know what type of solenoid this is that I can pickup at Kleenrite?

I haven't read this thread but it's rare for a solenoid to go bad, much less all of them. Test the solenoid coil with an ohmmeter. Look online for instructions. Check the common wire connections on the manifold to make sure there isn't a open circuit in there somewhere. That wiring is too sloppy to be like that from the factory, someone has been working on it before

 

[Blanco]

Your first problem was the fuse. Now that that is fixed check if you have voltage at the solenoid. If you do then pull the line off the back and see if tire cleaner comes out. If it does not then your solenoid is stuck. You can take it apart and clean it or buy a rebuild kit. See attached.

I appreciate you guys not getting tired of me (yet).

I have my multi-meter and it shows 24v when I put it the leads on the yellow cable and green (ground) - in the picture.

Should I also be getting 24v on the white cable and the ground at the same time? (I think this is 24V AC if I am not mistaken)?

In other words, there are 3 ports on the solenoid (yellow / white / green). I am getting 24v on yellow + green, but on white + green, I am getting nothing.

 

[Greg Pack]

When a particular bay is energized you should be able to get 24V across the yellow and white. if you can get voltage to ground but not to white then your problem rests with the white wire. As mentioned above it looks like someone has been working on that and may have made a bad crimp. trace it backwards towards the panel.
