New info if anybody's still reading this: I recalled that when I first went to hook it up after thinking it would work with the new heavier gauge wire, it sparked and popped when I connected the negative cable to the house battery. I opened the Ctek and found the one of the blade fuses on the...

> All the lights on the charger come on for two seconds when I'd connect the ground, but then it would go off, however I did notice that the led indicator for current saving mode is on Look at the manual for LED error codes. - yeah, there are error codes but doesn't cover what I saw. > I...

Okay, when I last posted I didn't see all the other replies for some reason, but I probably spoke too soon. I was hopeful because it worked after i decided to use jumper cables from the starter battery + to the charger input, and from the starter - to the house battery -, per wiring diagram...

John61ct, thanks for your help. I figured out the problem. The cable from battery to the charger was too small gauge, even though it was specified in the installation manual.

I just saw a video where the guy switched to heavier gauge wire and that solved his voltage drop problem. Even though I am using the AWG specified in the manual, maybe I should change to and see what happens.

I don't know if the unit ever worked, this is the first time using it. Ok, what I know now (I just came in from the garage, so I'll have to check the other things tomorrow): House battery is brand new AGM, currently 11.84 v. Voltmeter at starter battery is 14 something v. I tested with...

Thanks john61ct. It seems like the ctek is not getting enough voltage to come on. Specs say it has to have something like 9. When everything is connected according to install directions , and I test voltage at the input from the starter battery, it’s only 5 or 6. I disconnected everything and...

I have installed this charger in my truck to charge an axially battery to power a fridge and lights. Everything is installed as the instruction call for, the only variation is that I installed a ground post connected to the chassis where I could connect all the other ground wires- fridge...
