2 images of rediline inverter and batteries
There are several videos that exist of Stan Meyer starting up the dune buggy. The most widely viewed one
is the "Backyard Buggy Demonstration" in which Stan Meyer and Charlie are using a fuel cell to start that version of the buggy.
In it the butterfly valve is held open by a 3x5 card? and then removed once the car has been started. After the car is
running, it is switched over to the HHO fuel and the buggy successfully idles.
A later version of the buggy had a rediline inverter (colored light blue) To start the vehicle a switch located on top of the inverrter
was turned on. In the image below, it appears as though small deep cycle or perhaps motor cycle batteries were located under the
inverter to provide the initial start up power. The current was then converted to 120 v AC power to drive the electric motor that turned the
rotor of the y configured alternator.
I did not run the photogrammetry program or pantone color search on them, but perhaps a member can correctly identify the parts
It looks like the generator base might have held 6 or more of the batteries. The batteries are about 4 inches wide by 6 inches ;long

Thanks very much Jim!Did Stan ever mentions about the voltage on the cell?resonant action about the alternator?
-
That blue generator is a rotary inverter... It turns a ac generator stator and rotor coupled to a DC motor to turn 12vdc into 120vac.. I used to have one of them... They were used on power company utility trucks back in the day.. Maybe they still use them idk.... So if this was only used during start up that would mean Stan had another generator somewhere powered by the buggys engine that would power his ac motor once the engine was running..

Thanks for the input. From what I can see from the images, the electrical system consisted of some batteries, the rediline unit,
an electric motor/generator? and a y wound deregulated alternator. At his stage in the development Charlie would use the shutoff valve
on the top of the waterfulecell to regulate gas flow .If the part number of the gray motor can be determined, then one would have
a better understanding of the design parameters.

One thing that has always boggled me about this setup which i think donald originally brought to my attention is that it seems so lossy with its multiple stages of converting power.. DC to AC (redline inverter) then Ac to Ac (AC motor to AC alternator) then AC to DC (rectified/ switching losses from alternator output) .. Each converter has its own percent of loss in mechanical and electrical.. which all them conversions work against total output in comparison to total input.

If the batteries are running the rediline and the rediline runs an ac motor which in turn, runs the deregulated alternator to cause hydrolysis, how did the batteries get recharged? If not and the batteries were simply running down, then was Stans buggy essential using stored up battery power to indirectly hydrolyze water to HHO gas to run the buggy. How were the batteries being recharged?
Where would a separate alternator normally be found on 1500 cc engine?
-
Well I would assume that there is a charging system being powered by the motor... Something like another alternator which is used to charge the batteries..
-
the bateries were charged by the stock alternator.
-
They are three alternators on this buggy, one behind the driver seat, one on the driver side at the bottom of the motor, and the stock one on the motor. Highlighted in blue are the added ones other than the stock one.

Ronnie i noticed the 3rd alternator very long time ago,but was not 100% sure,but now that you pointed out,i'm 100% sure ,it shows beter in this screencapture
-
Good deal Adys15, That is a better photo. That should remove all doubts they was three. One for the electric motor for start up. second one for after it is started and third stock one for the engine and all electrical of the car.

Jim do you have this picture clear,without the white label on the bottom?
-
One "problem" is that Stan used the chassis as a testbed for different configurations, The photo from the WTVN demonstration, the backyard buggy demo video, and the video clip in the GNP bookplate are all of different configurations, over a period of years. So even though one might see two generators or alternators in one photo, it doe not mean that they are still part of the configuration several years later. I'll ask GNP if they have other views of the buggy version you are asking about and if they will release it for posting.

Thanks for the effort Jim!Looking forward seeing them.
