Wait, this is positive ground? Do I hook the charger as BRN/PRP > Black (CTEK) and RED > Red (CTEK)? I think I know the answer but do NOT want to fry a harness I spent months building.
Yes, always positive to positive and negative to negative regardless, so brown/blue connects to charger negative black, and red to red.
If you were to connect the CTEK incorrectly then I would expect it to cut out and light the red problem [!] warning.
