radio suppression kit for non shielded ignition engines
« on: August 30, 2016, 01:20:20 AM »
I got the kit a while back ant thought it was a bond strap kit. It did have a few straps but the kit had a new wire harness for the generator, condensers and star washers. Here are the instructions for the kit. You can use this to make up a kit for your self.



















Here is a photo of the kit



Another kit I got is to convert the shielded ignition over to a radio suppressed ignition system with the use of resistors in the spark plug ends. Here is a photo of that kit. Sorry, no instructions on this one.



I will post more stuff when I have time.

Thanks for sharing Steve.  I'd like a kit myself, but if I can't find one this will come in handy.

Did you notice on pg3 and pg4 that the diagram shows the "rain gutter" installed under the hinge seam between the top and side hood panels?  First time I've seen this somewhere besides in photographs.  Now it's documented!

I have the remnants of one of these kits on my HT. This will help me put it all back the way it was.

Thanks,

 I notice that at the top it says to be used only when replacing one engine assembly with another.
 I wonder?

I did check this. I believe it is to replace the engine with shielded ignition with one with out shielded ignition. According to ORD 9 supply catalog E-3832 is the engine with the radio shielding system and engine E-8450 has the filter and bond straps for radio noise suppression.

Anyone found a description of the bonding straps that are listed, i.e. length, width, etc.?  Is there a source for them?

I have a kit, Tom. If you jab me, I'll measure the bonding straps for you.

I measured some on my halftrack and this is what I have.
Top of engine head to firewall - 1" wide by 12" long with a 9/16" hole on each end.
Hood bond straps - 1" wide by 10.5" long with a 9/16" hole on each end. Need 4 straps

In the kit above I dug mine out and measured the best I could without unwrapping it so I don't have hole size but guess they are for 9/16" hole.

2 straps at 3/4" wide by 5" long
2 straps at 1" wide by 10" long
4 straps at 3/4" wide by 12.5" long

I will post some photos when I can.

Thanks Steve.  If anyone knows of a kit floating around out there, please let me know.  Or if you know of a source for the straps...

Here are the photos for my previous post. You can buy these bond straps at any auto parts store or on line.
