It will die if the battery connection is broken - the Caddie had an alternator that is 'overdriven' using a belt and pulleys - the Polaris alternator is driven off the crankshaft and does not start to charge until between 2000 and 2500 RPM. The Polaris is operating at a total loss until engine speed is increased, therefore if you disconnect the battery there is no 'generated' voltage to supply the ignition, but don't try it - I have seen many damaged ignition systems caused by jumping a dead battery to start a dead quad and then trying to charge the battery by running the vehicle. Honda, Yamaha, Polaris and all other models share this shortcoming. No, it will not run off the alternator - find and fix the problem to avoid more costly repairs down the road.
