1944 C-15A-Wire-5 Restoration

The devil is in the details . Here is the weird gizmo now installed . We also see a transplanted latch or bracket under the panel handle . I took it off my other box . It obviously there to lock the handle with a paddle lock because there is a hole in it .

[Robert Bergeron]

I sealed the charging compartment door ( fridge door ) and adjusted the hinges and handle to make a good seal . I also sealed the holes were the armoured cables come in with mastic ( glazing compound ) , what we used to seal glass panes in window frames . Posted the warning sign so now we are ready for another function test with both generators running . Too bad i don’t have a Decibel meter . ...

This is the sealer that was used to seal windows and just about everything else before silicone .Glazing compound .

Here is a pano of the interior . Still a lot to do ( too long to list ) but getting there.

Hi Robert: if you have a smart phone you can download decibel meters for free. I have one called Decibel X. I’m sure it is not 100% accurate, but the readings seem consistent and in the right range with what would be expected. I think it’s quite close.

Thank you so much Wayne . That’s an excellent App . Here we have the truck with both Chorhorses running and charging up the batteries . Next i will report on the noise both inside and outside .

[Robert Bergeron]

With the rear door and all windows closed , the generator compartment well sealed , both outside shutter doors wide open i had 79 Decibels while sitting in the radio operator seat facing forward .

Here is the reading at 100´ feet from the box at 66 Db . I had 73 Db standing 10 ‘ feet from the box immediately in front of the Briggs & Stratton muffler that’s just over the rear right tire . Tomorrow i will try with only one generator running .

Noise tests day 2 : With truck running and No 1 ( upper ) Chorehorse running . Operator ´s seat inside the box : 73 db . Outside 10 feet from truck : 79 db . 50 feet from truck : 69 db . 100 feet from truck : 61 db . I don’t see why the 2 generators would have to run at the same time anyway . The results are very similar with the truck engine not running by about 1 db .
