Here is a good Youtube video for testing 3 phase motor:

If you have the latest iPhone Pro Max, it may help. I have got better results on my iPhone in enhancing such images.

I have the JC system installed, which includes the weep functionality. While I don't have check valves on the HP line, both the tire cleaner and Soft Free, which are connected via tee to the HP manifold in the bay, do have check valves. I've ensured that all the Soft Free check valves are...

Yes, good idea. I am going to give this a try.

Cool, thanks! So, my weep solenoids are supposed to be normally closed, right? I checked the poly line, and no water came out, confirming they're closed. Then, I tweaked the weep temperature, and they all activated, flushing out water. The mixture tank level stayed the same, though in my...

Yes I am based in Houston. I'm still trying to understand how my weep function operates on my JC system, as it's not something we frequently engage with or maintain. Currently, I've closed the ball valve that links the weep to the pump, which is accompanied by a check valve. Additionally...

The presoak, along with the soap and clear coat, is injected into the cat pump. The tire cleaner and Softfree, however, are fed through a separate line, which is teed on top of the bay. We are experiencing this issue specifically with the presoak others look good.

Thanks! That's what my initial thought was. I did look over all the solenoids, and I ended up swapping out a few that seemed rusty or had sticky stems. Others looked ok. I also added a check valve, just to rule out this issue. I thought it would be airtight, with no drops. I ignored the drops...

So, I've got this weird thing happening with my presoak mix tank on my JC super saver setup. It's acting all wonky - the mix seems watered down, and the white tank isn't sitting straight (attached pic). I've tried a few fixes already: Swapped out the old Hydrominder for a new one. Popped in a...

Thank you everyone for your input. I know what I need to get now.

Does anyone know what is the difference between these check valves Brass and Stainless Steel? Why is the brass one so expensive?Which ones do you guys use? TIA

Hey, thanks! No hot water tank here. Just to clarify, you're thinking the check valve in one bay's weep mizer is acting up. It's causing water to go backward when customers use that product (CAT pump's running + solenoid's open). If that's the case, it should have happened with other functions...

Hello - I've got Jim Coleman super saver stand, and I'm dealing with a bit of a glitch. It has a rinse tank and each bay has a ball valve and check valve. Right below the ball valve it T's into soap, wax, and presoak. The snag is when the brass plunger/stem gets stuck, the rinse water backflows...

Hey folks, a quick update on how we sorted out the issue. Turns out, the culprit was the motor gearbox throwing a tantrum. Swapped it out, and problem solved. Also, that C110 error code? It's the machine telling us a step's taking longer than it should that's what it means. Makes sense now...

Usually, the machine tends to stop right at the front of the car. When it moves from the back to the front of the car and is about to go back for a different wash pass, it suddenly shuts down. Today was a bit different - it stopped in the middle, but it was still in the process of moving from...

What does the C110 error code mean, thats the first one that popped up for wash #7319. I cannot find this in the diagnostic code list document.

Hey Darin, Been using your old threads to toss around some ideas with NCS tech. The issue popped up again today, even though we thought we had it fixed. Here's what we've tried so far: Swapped out the front proxy switch Changed both left and right tire photo eyes Checked the motor voltage...

Getting the diaphragm properly sealed fixed the air leak. Thank you.

Hello - I'm gearing up to do some maintenance on my self-serve bays with the Jim Coleman system. I've got two main tasks in mind: Greasing up the booms Giving some love to the motor that drives the Cat pumps I'm kind of a newbie at this, so I've got a few questions: What kind of grease should...

Yes, it is in the right direction. I will check the diaphragm assembly when I am there on the property.
