I am planning on putting a switcher in my defender. I have the switcher with wiring from Bob Roberts. I didn't get this from Bob so if any directions originally came with it I don't have them. Looks pretty straight forward. My question is more about the coin door lights and any other power to the coin door that would come from any connector on the original Linear PS other than 4J2. Actually I believe 4J3 from the linear PS originally powers the lights on the coin door.
Reading Bob's Williams coin door lamp circuit write up it sounds like you can disconnect 4J2 from the original linear PS and plug it to the connector from Bob's switcher to power the boards. As for the coin door lights, if I interpret this correctly Bob is saying I can still power them off the original 4J3 connector of the linear PS. Only difference is he suggests cutting the 27VDC line and putting a rubber band around the coin lockout to alleviate heat.
Does this sound like the correct way to set this up without causing any unwanted issues?
In the text in the lower right hand corner of this diagram Bob comments, "if using the linear, be sure to unplug the AC line to the switcher." I'm guessing he means if you are using the bypass he shows in the diagram and changing between either the linear or the switcher? Or am I wrong and he is saying you do not want to use the linear and the switcher together in the cab at the same time as I mentioned I was considering doing in my comment above?
