Review on ⚡ Weego JSMT524 Marine & Auto Tether: 2-in-1 Jump & Charge for JS6 & JS12 by Kevin Lawson

Doesn't work with Tender 800 waterproof battery Installed a new battery on my Honda bike with this Weego cable. When the Battery Tender 800 is connected to maintain battery power, the tender simply flashes the yellow LED. I hooked up a voltmeter and it shows the Battery Tender 800 turning on and off. Left several hours without changes. Plugged in the Optimate Pro S charger and it did the same but shut off after 20 minutes. So I removed the Weego Tether and installed the standard battery cable that came with the Battery Tender 800. Now everything is in order. I suspect there is a problem between the Battery Tender 800 and the diode in the Weego cable. I understand why the Weego Tether has a fuse, but I don't know what the diode is for. So this Weego Tether doesn't work in my app.
