Late thread reply but on the ctek there Is a red wire which needs to be connected to a 12v ignition feed like a cig lighter point or even stereo wiring. The ctek needs to differentiate between when the alternator is charging and when it isn't.

Late thread I know but have you checked all earthing points? I had the same issue,I did have my aux battery grounded at my chassis but still wasn't working properly so just ran an earth cable from main battery to ctek
