i was parting out an 81 westy by my house the other day. Along with many needed parts for an upcoming project I am working on, I got a Behr in dash AC and a large box that was mounted under the rear seat next to the water tank. It has printed on it: Charge Sentinel Power Converter, Progressive Dynamics,  25 Amps Output, includes battery charger. I found some info. in the archives on the Behr, it will work quite nicely with the turbo diesel westy I am building. But I could not find anything on the power convertor! It looks like it might be a cool piece, if anyone has any info. on it they could share I would appreciate it....Rex
