On that basis and on my own feelings regarding the 150uf charger failing initially and almost instantly, I will not be in any hurry to Test or even use the New 150uf charger, especially with a Brand New control board fitted to the Sherman! My main reason for ordering a second charger in the first place with the wheel, was to give myself the option if required rather than a regular need to charge at 10A and it's also useful to have a back up.
