I'm just about finished with putting my EQ6 together again after installing the excellent belt mod. I was intrigued by a site I found in which the author claimed to get PE of 5 arcsec peak to peak and an RMS PE of 1".

He uses an ammeter on the motor which I guess is simple but how would I do that? Simply use a multimeter on the + and -ve wires from the PCB to the motor?
In fact, the chap has a lot of good mods on his pages..
