Re: Ampro New Educational - motor woes, issues and solutions
wd40addict, it's not C23, I already replaced that when I first bought the projector as it started shorting. The capacitor I am referring to is within the motor casing itself and is wired between the two brushes for the commutator. As far as I'm aware it isn't actually noted on the schematic. It's value is 0.05uf, different to C23 which sits inside the bottom of the projector and has a larger value of 0.5uF
Now I have the points cleaned and adjusted the best I can, I'm going to run it for a while and see if they bed in a little. The motor is now running correctly but there is noticeable drops in speed every now and then. Hopefully with some use a good contact will be made between the points and rid it of any need for more attention.
