Power inverter that takes high voltage down to usable 12v for small battery and accessories, lights, dash, ect...

Thanks!
So how do they keep the battery charged on the later cars? Do they still use the inverter or is it replaced by an alternator? And why the change, there must have been a problem with the original system or maybe it was less expensive to eliminate the inverter? Enquiring Minds...
 
No, actually they added a motorcycle battery for power backup of the 12v systems. The rest of the system is similar although a bit less robust in my opinion...
