Re: Out of 40amp slots

Brandon,
The window motors actually draw about 20 amps at stall. (one slightly higher and the other slightly lower.) Collin you were looking at max power not current I think.
It is important to remind everyone that with increased motor usage, available electrical power from the battery will become an issue. You cannot simply run all the motors at the same time. The terminal voltage on the battery will fall to the point that the Crio either disables all outputs or it reboots. Be careful to watch terminal voltage as displayed on your dashboard while practicing. Expect that transients are much worse than what is displayed on the dashboard.
