Not to discount the IFI manual, but we have had 884 controllers in the past blink red that we traced to damaged controllers. They still were operational, but were not repeatable to the PWM input signals being sent.

A 30 Amp breaker will not protect the 884 from a 50+A momentary spike if changing direction too fast. This spike is in micro-seconds, a breaker will average currents over a period of time. All of that momentum from full forward to full reverse has to go somewhere. The current spike is probably not measurable, but over time, if done enough, will breakdown any circuitry protection built into the 884.

This year we implemented controlled speeds to the controllers. We haven't lost one yet. We cannot say that for the previous 2 years.
