Make sure to watch Part One of my 1973 VW Super Beetle Cold Air Blower Modification Video so you have some context for this video.
Part two 1973 VW Super Beetle Cold Air Blower Modification mainly consists of me finally getting and installing my new blower motor which is essentially a 12 volt 16.5 Amp Server Fan controlled by an RC type speed controller. This new motor turned out to be exactly what I needed get some proper airflow into my 1973 VW Super Beetle. The previous Bilge Boat Blower did not have nearly enough pushing power to force air through the internal dash system as it was only around 2 Amps.

As the speed controller is basically an Remote Control Car ECU it has some setting that I needed to make sure where set for the battery type in my car. By default the ECU was set to a Lipo battery which has a constant voltage. A Lead car battery doe snot always have a constant voltage and can fluctuate a fair bit, this makes the ECU think the battery may be low so it down regulates the current making the fan speed go up and down, mainly down...
I switched the ECU battery settings from a Lipo to a Nicad Battery as a Nicad Battery is a lot more similar in terms of the voltage ups and downs of a car battery and this fixed the voltage regulation from the ECU to the fan problem I was having.
I also show off my Mr. Heater Portable Buddy Heater I know use to heat my 1973 VW Super Beetle as I ditched the built in Gas Heater I had before that was unreliable.
