Hi all, I hope someone is able to help me!
I have an Automower 430x. Less than a year old. The mower will run fine through about 1 battery. When it's out on it's second 'run', it will just randomly stop due to 'No Loop Signal'. The charger base is flashing blue instead of solid green. But the loop signal is obviously intact since it had just been running.
I'll let it sit overnight and then start it again in the morning, and it works fine. Until the second run and then the charger base starts flashing blue again.
Any ideas? I saw another post on here talking about signal degradation. I have a few scotchlocks (or whatever the name is) in my boundary line, and I haven't installed guide wires yet.
Please help!
(Edit: I notice that when I post this, it's changing my words. So hopefully it's translating/posting correctly.)

Is the base light green or solid blue when the mower works fine?
How long is the boundary wire (limited to 800m using standard cable)?
How many is a few scotchlocks?
Can you easily find/inspect them?
It looks like one or more of them has a bad signal - only a few wires of the cable still in the scotchlock and in the morning, when it is still humid, the other wires transmit their signal thanks to the humidity, but as soon as it gets dry (or ultra-wet after rain) the signal loss exceeds a certain limit.
BTW, it makes no sense to run a 430X without guide cables. Maybe its time to install them and try to connect them to the boundary wire at one of those existing connections. Once the guides are installed, you can easily find out which part of the boundary cable is defective. (by connecting each guide to the base station as if it were a boundary wire).

It looks like one of the two or more of them has a bad signal - only a few wires of the cable still in the scotchlock and in the morning, when it is still humid, the other wires transmit their signal thanks to the humidity, but as soon as it gets dry (the ultra-wet gold after rain) the signal loss exceeds a certain limit.

The base light is solid green when the mower is working. I don't know how long the boundary wire is. It'd be a complete guess. I have at least 5 scotchlocks though.
The reason I have no guide wires yet is because I haven't finished the install. I have it running just in my front yard until I can complete the setup in my backyard. That's when I will run the two guide wires. Any of the scotchlocks are less than 8 months old. Is it typical for them to go bad this quickly? I'm also wondering if maybe the connections to the base are corroded? That's easy enough to check I guess.

The best way to find where you are is to use an ohmmeter (multimeter) to measure the resistance of the boundary loop. The rules are:
Its resistance should be lower than 15-20 ohm. Above 30 ohm the mower will no longer work.
You can then also test the loop resistance between boundary wire left side and guide cable or boundary wire right side and guide cable.
To get a long enduring installation I would not use scotchlocks but solder the connections and use shrinking tube to isolate against ground (which is not really critical). Or use a crimped connector with shrinking insulation.

Oh, so the Scotchlocks aren't the best option? I would much rather solder them and use shrink tubing.

Hello....only a few wires of the cable still in the scotchlock and in the morning, when it is still humid, the other wires transmit their signal thanks to the humidity, but as soon as it gets dry the signal loss exceeds a certain limit.
Don't run a 430X without guide cables and try to connect them to the boundary wire at one of those existing connections.
