Moi from Texas sent us the following question. Question: Hi I have a question about my Apollo 3500ETL, why does my system stop working making me reset the motherboard to get it to work again? Answer: Moi, you have one or more of the following issues… first check the “Auto Reverse” sensitivity setting, turn it clockwise until it takes a little more force to reverse the gate yet it remains safe. Next you will want to check that all your power connections are free of corrosion and tight and last you will want to check that you have a solid, good ground to avoid the system going into “safe” mode when you have a power spike or brown out.
