Overview
How to replace a temperature/humidity sensor, a broken rain gauge or a faulty rain gauge cable.
Disconnecting the raingauge cable
The white cable connector has 2 tabs that locks the cable in place, one on each side.
Using a small screw driver or similar, move it into the slot and bend the small plastic tabs backwards at the end that faced away from the sensor 
Check rain gauge functionality
If you have had intermittent raingauge count or it once worked and now it stopped, maybe a god idea to check the rain gauge is working from the connector and out. This requires a multi meter
Use the setting Ohm/resistance on your meter. Put something heavy in the scoop and push it to the bottom so that it doesn’t automatically go back to it’s original position.
Now measure the resistance over the two pieces of metal, should be about 1k/1000 Ohms.
Rain gauge malfunction/cable change – step 1
If the cable is ripped or damaged, if you didn’t measure 1k over the metal connectors or you just want to be really sure that the rain gauge is working, follow these steps.
First we need to detach the scoop counter board, it is a board inside fastened to the golden nut or just a screw. Loosen the nut/screw
Now flip the box over and pop the bottom of the box out. Note the black wire has zip-ties attached to the wire to reduce the strain on the cable. There is one on both sides of the bottom piece. Important when you assemble the rain- gauge again
Rain gauge malfunction/cable change – step 2
The block terminal has two wires that transports the signal back to the CT when the scoop is activated
Before you start taking anything apart, check that the scooper is actually working properly. Measure over the two terminals that the wire was connected to. If you have success here, but didn’t when measuring through the cable, it most likely is a bad cable
If the screws are not tight, the cables are not firmly inserted and tight, this could be the reason for the failure. Loosen the 2 screws and the cable will pop out. If you cable looks like the middle picture, I suggest you straighten the cable out like the picture on the right. This could very well be the reason to why it stopped working.
This will maybe add a little more strain on the cable, but the zip ties should take care of that.
Rain gauge malfunction/cable change – step 3
Now it is basically just going backwards, to assemble the whole thing.
Insert wires and tighten enough, making sure no wire strands are accidentally getting into the neighbor’s terminal input.
Insert the board into the rain gauge enclose, add the nut to the bolt sticking out. If you lost the nut, you can unscrew the screw and use that to tighten it down with.
Now it is time to pop the lid back on, making sure the two zip-ties end up on either side of the bottom plastic.
When you insert the rain gauge connector to the board you almost can’t do it wrong. Just make sure the little white piece of extra plastic is facing those two small tabs. Those are the locking system of the cable.
