For the altenator one positive to positive on battery
. One positive to charge controller. Balmor altenator has a designated ground. A click can imply a couple of things. Among them are low battery voltage and poor connections. I assume you have checked battery voltage. For trouble shooting purposes try taking a lead of some sort (jumper cable?) from the ground side of your starter to a designated ground. Check resistances on your wiring
to check your connections. Good luck.
