I did have to resolder the yellow wire tonight (adjacent to the gray) so possibly something is crossing there.
That would explain it. Examine closely.
However I am not using any functions currently, all outputs should be zero.
Doesn't matter. Inside the LM at each output is a transistor which has the ability to block very small voltage from causing current to flow in reverse. But as the voltage increases at some point, usually around 0.6V, the transistor will go into breakdown, labeled V(be) in the datasheet, where current begins to flow backwards and the short occurs. Whether or not you are using that function is irrelevant. It is quite possible, due to the wiring problem, you are exceeding V(be) on an LM output when the throttle reaches 1%.
I do have one LED wired in (rear light), and I believe that it is in backwards (get a function short when activated), not sure if that could factor in.
LEDs wired in backwards simply do not light up. They do not cause shorts.
As politely as I can say this, it sounds like you have multiple wiring mistakes in your installation. Suggest you rip everything out and reinstall paying very close attention to the wiring schematic you included earlier in this thread. Make all your solder connections sound and thoroughly insulate all connections.
I suck at electrical, must be why I went mechanical. Lol
Hey, everybody sucks at something. That's why we have friends to help us out.
