Dyna S problem

Hi everybody... Having problem with my Dyna S ? It seems that when I press the right side of the module in the centre with a screwdriver to the back plate, the RPMs rev up and sound nice. The problem is it won`t stay adjusted that way as soon as I let the screwdriver go . It will not idle right...like it seems to be warped or something. How would I be able to fix this? Thanks in advance for all comments.

You should contact Dyna.

People have said that they are very good helping out.

People also say that if you need a new setup that they will offer you one at half price.

This is what others say, this did not happen when I contacted them.

They could care less and actually offered no help.

But you might get the helpful tech guy.

Sounds like the mounting plate isn't grounding properly. The plate of the Dyna when tightened down with the 2 mounting screws acts as the ground point for the modules. Early Dyna 2s (Not sure of the newer models) had a plate that was too thin and didn't make good contact when tightened down. I used star lock washers under the mounting screw heads in order to force a good ground contact point.

Yes and yes,
definitely sounds like a poor grounding issue.
It could be slightly oxidized on underside of mounting screws, mounting base etc.
