Well here's another video I uploaded that has my new clamp meter showing the amps.
Looking at my ammeter, it seems to stay at around 4.3A. Does this mean that if things were working right, it should be about 8.6A when I have 24V running the motor, or does it not work that way?
As far as wiring and connectors, I'm using 10 gauge wire (I think) and 8 gauge ring terminals. I have the connections on the battery side connected with the washer/nuts that came with the battery. On the wheelchair motor side, it's not as good I guess - 1 wire is shoved into the terminal of the 4-pin connector coming off of the wheelchair, and I just manually touch the 2nd wire to the 2nd terminal of the same connector coming off the wheelchair. It does create a small spark every time I touch it like this.
When I did that test that I mentioned in a previous post with both batteries, it did seem like the motor ran twice as fast (briefly), but have no idea - I didn't measure the speed (don't even know how), so it's just a guess.
I have not run the motor without the gears and/or wheel yet. Taking apart the motor makes me slightly nervous as I am slightly worried that I won't be able to put it back together right. The shaft/wheel does turn with resistance, but yeah it turns.
Looking at the video(s) I linked, am I doing this unsafely? I really don't want to be electrocuted.
