M201 - earth straps / jarretières de masse
Just when I was beginning to think that there wasn't much more about M201s that I could put up on the site Louis in South Africa asked me where all the earth straps go. He's been doing a full restore on his jeep but couldn't find the information needed to put the straps back in the right places on any website. So here it is based on the information provided in MAT 3633-1
Unlike the series Land Rover's of the British army where there was a specific 24 volt model, the FFR (fitted for radio), all Hotchkiss M201 24 volt models were built so that a radio could be fitted if required. The standard equipment included a screened ignition system, enclosed and filtered dynamo and regulator, condensers on electrically noisy equipment, and a filtered power box to which a radio could be connected. In addition, earthing straps were fitted at a number of critical points to insure that radio interference would be reduced to an absolute minimum.
MAT 3633-1 gives the detail of five non-standard strap types (A-E) which have been included for completeness along with the references for the standard straps, details of which are given below.
