Re: spike relay problem?

Please tell us what colors the light on the Spike is showing. Yellow means stop. Green means forward. Red means reverse. Off means both forward and reverse at the same time, which is probably what you're telling it to do when you think you're telling it to go from forward to reverse. It's just like stop, except that both outputs are at battery voltage instead of both being at no voltage.

A Spike has two completely independent relays. Forward and Reverse are not two different states of the same relay. They are separate relays which each can either be on or off. If you want to "go in reverse", you have to turn the reverse relay on while simultaneously turning the forward relay off.
