Hi Warren,
I don't want to drag this on. I understand the challenge to fix the unit. I
have a name brand Dewalt 9 volt drill. One of the batteries went dead and I
threw it away and realized afterwards could have fixed it. Any way the
replacement battery was $50 which I did not buy. Name brand is not what it
used to be! Two weeks ago I bought a 12 volt drill with two batteries at
Canadian Tire in Sarnia. (not kidding). What would that work out to in U.S
dollars! Almost as good a deal as Max.
It works great still can't get over the price.
Bruce.
