Turn signals

[Jack Innes]

Thank you Robin & Terry.

Now knowing that a replacement is available I took the old unit apart. It is in fairly good condition & the problem was corroded points similar to what you find in old voltage regulators. Once cleaned I now have functional turn signals!!

With the help of the M37 wiring diagram & a little studying of the relay box I now also have brake lights! The wiring seems odd in its numbering but not impossible to trace.

For security I think I will order a relay box & have it shipped to my place in Kansas to be retrieved at a later date.

I have attached a picture of the power plant as well. It is now back in & running. (With new everything that is mentioned in the manual as instruction #1 - remove engine. Front brakes, fuel pump, etc.)

Hello, i am new to your forums. I have a 1952 M38A1 USA version 24V jeep. I have been restoring it, I am looking for a wiring diagram possibly from the CDN 2 or 3 that will show how to wire the turn signals. I installed a wiring harness from Peter Debella jeep parts that has wires ready for turn signals. I just want to make sure that I hook up everything the way it needs to go. I recently installed the military Directional Control flasher unit with the Canon plug 3 wire. I like how my Northern friends take a good product and improve it. Any help with the diagram would be most appreciated.

Some soldiers would disagree with you on the last point. Some Canadianizing practises have been pure stupidity!

What you are observing is differences between the design when it was 'sealed' as a variant by the US military. Our buys tend to be towards the end of the production runs, and technology matures. The differences between our M38A1 CDN1 from 1953 are readily apparent to the M38A1 CDN3 contracts from 1970 and 71.

Hi Randy. Here are the CDN2 (Fig 1) and CDN3 (Fig 7) wiring diagrams respectively. Hope that helps.
