My Dewalt Drill trigger is failing, sometimes I have to hold it on for
30 seconds or more while I disconnect and reconnect the battery, move
the fwd/rev swtich around, spin the drill chuck, hit the drill with my
palm shake it... it comes on when it feels like it. I haven't correlated
it to moon phases, yet. I found a part on ebay for $63 so I think I'll
try fixing it first, otherwise it's a new drill purchase instead
extending the life of this old beast.

This is the assembly

It looks similar to this

Has anyone taken one of these apart? Does anyone have any idea how these
are constructed? it looks like a sizeable heat sink so I'm guessing it's
a wire-wound pot.



** Not at all likely, almost certain to be a Mosfet drive using PWM.
Does it not make a whistling sound when you pull the trigger in slightly?

No sound at all Phil.
