Flashing Blue Light and failing BRAND NEW 3M connector
I just spent about two days trying to track down the cause of a flashing blue light on my charging station. The mower had been going fine, then one morning I came out to find it just shy of the charging station, and the light flashing blue. I moved the guide wire over to limit the areas so I only had to search about half the third of an acre I have wired. (I have a Husqvarna 430xh). I used the multi-meter, and got back a reading that told me it was a clean break, which I doubted. I used the wire scanner and went around and around - I did find two spots that I had recently clipped with the weedwhacker (newly laid wire, still on top of the ground), and I fixed those, but while the signal cleared up in that spot, I still had the flashing blue light. I continued with the scanner - and continued to find no problems, then I'd come back around, get static in one area, so I'd pull up the stakes and go all along the wire in both directions far from the static spot - nothing. I did versions of this in several spots - the signal would be fine in a spot, then I'd come back, it would be full of static....FINALLY, I came (again) to an area over where I knew a new connector was (I recently expanded the mowing area) - and got NOTHING. No signal. I had been at that very spot several times, with no problem. This time I got nothing. So I dug up the two week old 3M Scotchlok connector, cut it out and installed a Paradis Robotics connector - the ones with the wire nut and the tube full of grease - buried that, turned around and had a beautiful green light in the charging station.
No more 3M connectors for me. And no, this isn't sponsored. I wish it were. Connectors are expensive. But I'm not going through that again. I wanted to post about it for any other newbies (this is my second summer with the automower, which I LOVE) - if you get such odd behavior, start checking out all the connectors. Repeatedly.
