How to update motor and wire clips with an old wiring harness

This article has trouble-shooting and how-to replace components for a wiring harness produce from 8/26/22 to 10/1/23.

Units produced before October 1st, 2023 have an older wiring harness color pattern and older wiring clips. These clips are direct inline rather than the current WAGO Clips that are more like a "splice" together clip. 

 

Overtime you may want to swap out the motor or upgrade the wiring clips due to corrosion or other issues so below outline how to do those step by step. It's also a good guide to troubleshoot what could be the issue. 

When you say older wiring harness, what do you mean? 

Here are some pictures and a quick video glimpse of the wiring harness that was produced in between 8/22/22 and 10/1/23. If yours looks like this one then this article should be helpful. 

Troubleshoot First

Whenever their is a power related issue, the first question we ask is what the input power is. If it's a wall adapter/transformer for 110VAC then make sure the output is 12V and 10Amps. Often adapters are rated for 1 Amp, 3 Amp or 5 Amp and we recommend to have 7.5 Amp or 10 Amp to make sure there is enough current to the motor in high torque situations. If it's a battery and you know the battery is charged, then let's take a look at what else could be wrong. 

 

Step 1

Check Motor Directly

 

If you have an older harness and you're confident the input power is working, it's easy to get overwhelmed with not knowing where to go next. The next check to make for the OGO is to see if the motor itself is not working. Below we should how to wire the motor direct into the harness for 12V. This is not practical for using the toilet because the motor with turn the whole time, but it will give a quick way to see if the motor is the issue or if some other wire connection is the issue. 

 

In the pictures and videos below, we have a new motor with a white and black wire to replicate what it would look like with a customer who recently received a new motor. Keep in mind that you can still check older motors the same way but the wiring is equal to the following:

1. White on new motor = black on old motor
2. Black on new motor = red on old motor

 

Step 2

Check if Button Works

Wiring the button into the system will allow you to have a functional unit that is a press and hold situation. This is less common of an issue but if this works and a full wiring hook-up does not, then it indicates the timer itself does not work. It is not 100% ideal but it gets you back up and running until a new timer can come in. It's also a good first check on the button to make sure there is not corrosion on the button wiring.

Step 3

Change Out All Wiring

In a perfect world, we like to replace older motors and harness clips with our newer motor and newer WAGO Clips. There will be 2x 5-pin WAGO clips and 3x 2-pin WAGO Clips

Now we can start fresh and remove all the old wiring clips to make sure each wire has a good amount of wire exposed and it's ready for a new clip and motor install.
