1. The macerator is a pump/grinder that pumps the contents of the holding tank from standard hose fittings located under the tank age compartment door, normally one on each side. 2. There is a three-position switch marked "Merge" on the dash. The center position is off, while the up and down engage one of two solonoids to merge the batteries using either chassis or house power. Among other things, engaging the merge switch allows the engine batteries to charge when the coach is parked with the electrical cord plugged in. The solonoids are located on the electrical terminal board behind the door at the right rear corner of the coach. These solonoids wear out, and should be replaced annually with new ones rated for continuous duty. 3. Yes, 1978 Newells have air ride. 4. The front terminal board (in front of the copilot seat) is powered by the engine 12-volt system.
