Newmar Ns-12-20 Nav Start Guard

The abrupt DC system voltage drop that accompanies engine starting can cause communication/navigation electronics to "dump" programmed memory.

StartGuard solves this problem by providing supplemental voltage to sensitive electronics while the engine is cranked. It contains a sealed rechargeable battery which is switched on-line to electronics when sensing the starter switch or solenoid is engaged. When the engine is running StartGuard automatically goes off-line and the internal battery is recharged by the alternator.
