Before I got my IMDN Prem in I emailed and asked my distr. About this bulletin and if they would be installing the cap kit since my dist was also installing a shaker.
They said the problem was with earlier runs of IMDN (assuming the first run pros) and that new runs didnt have this problem and didnt need the kit.
That being said she did say if it were necessary to install the kit either stern would have it already installed or they (the dist) would install it before shipping.
I looked over mine when I got it in and there is no cap kit that I can see anywhere on the node board that the shaker is plugged into or installed directly connected to the shaker.
I have not had any resets or false slam tilts at all. So maybe they fixed this issue afterall on newer runs and the kit is not necessary for them?
