What he said. Just buy the harness and attach it to your main battery.i just charge the primary.
Once its fully charged, the isolator opens to allow charging of secondary
mine does same thing.... How do you have your ground hooked up? I've got mine hooked to the factory battery , I'm thinking of changing the 2nd battery ground to the frame and see how the tender works then.So when the tender charges the primary up and the isolator blue light comes on and lets both batteries charge my tender keeps charging and never goes from red charging to green charged. Blue light never goes back off. Gages show 14.1 volts on both batteries so I know they are charged. The tender should go to green then! How does you guys work?

I think what they are saying is that the blue LED on the true isolator is enough of a drain that the battery tender will never "fully charge" the second battery and therefor the tender will not shut off. It makes sense to me. Also I wired my winch to the second battery and the dash switch for the winch has a LED light and so the battery tender is basically supplying power to both those LED's and will not turn off.

no it stays connected until the primary drops to 12.7So your main battery charges up, light comes on the isolator letting the second battery charge , when second battery is charged your battery tender will shut off ?
. No im saying if you have a radio or USB ports that stay powered 24/7 that will drain you battery.I think what they are saying is that the blue LED on the true isolator is enough of a drain that the battery tender will never "fully charge" the second battery and therefor the tender will not shut off.

right the isolator stays on once the primary is charged. The light is just status is maybe a milliamp not enough to run the batterys down in a year. My tender goes to float Mode once it reaches full charge.That's right! the blue light on my isolator is not letting the tender shut off when the second battery is charged.
