ORIGINAL: Slow and Steady
The Syssa IBEC works with any kind of battery and has been very reliable for me. I think it is smaller than the one sold by Chief. The Chief one also requires you to move the dedicated switch twice to turn the engine off. I have the older Chief version on my Yak. It doesn't require the double throw and also works great.
Got my Syssa IBE but havea question. What are the jumpers for on the end? Do they control input and output voltages? It came with no instructions and there aren't any on the website.
