Reviving this thread about a TK102-2 drawing an incredibly high level of current, as I am still having trouble with it. I've measured the current going into the charger (ie the current the charger is taking from the boat's 12V supply), which is 500mA. Then I've measured the current the tracker takes from the charger (ie the 5V feed to the tracker itself) and that is around 800mA. Left it running overnight, no change
So there's around 6W going into the charger and 4W coming out. But the culprit is the tracker itself, why is it taking so much? I actually have two trackers and they both do it.
If I unplug the cable into the tracker, the draw falls to zero so there's no short or anything in the cable.
The tracker draws the same with or without the battery installed (but switches itself on when the battery is installed, so the battery's connecting OK), and with or without the sim card. I've checked the meter calibration by measuring the current through a known resistance (nav light). Both trackers check out as genuine Xexun by running the IMEI numbers through the checker on the Xexun website
Hopefully this is one of those very simple things and at some point there'll be a "doh!" moment and it'll all become clear, just need to work out what the issue is..... is there a setting or something (that still leaves the GPS checking for movement) I'm missing? Or any other ideas please?! Thanks!
