Question:
Everything is installed and working with exception to reed switch light, It was running perfect before I installed the Roadmaster 766 Remote Battery Disconnect. As required the battery shall be disconnected prior to towing but once shut off is engaged, no reed switch lights but the braking system does work! Help not really sure whats going on. Now I would like to install the Demco wireless coachling system. Do you have any videos or diagrams for this? Thanks,

Expert Reply:
Since your battery is getting disconnected via the Roadmaster Battery Disconnect # RM-766 what you'll need to do is wire the reed switch directly to the battery as the power source instead since the wiring of the vehicle is getting bypassed.
This would be the same if you were to install the Demco SBS CoachLink 900 Wireless TranDemco SBStter and Receiver Braking Indicator Set # SM99945 as well.
