Outputs don't have enough power to push relays
I have a new Fusion Brain V4 which I bought in February. Today is the first day I've actually tried to use it. I have a battery on my test bench which I'm using to supply the fusion brain its power. The voltage at the battery is 12.2 volts right now. When I turn on an output on the fusion brain and test it with the same volt meter I get 11.52 volts. When I plug in a relay to that output, the relay does click but it also hums and then sporadically clicks back and forth quickly. With a relay plugged in, if I hook up the volt meter in parallel with the relay, I get 7-8 volts. Unplug the relay and I'm back up at 11.52. The relay works perfectly fine when it is connected directly to the battery. I even tested its current draw and got 81.2 milliamps which is well within the specs of the fusion brain. Why is power having such a hard time reaching the outputs?
