The fun part has begun

I had one already that was rather too good a guard dog. Nobody told him, he just decided to look after the den, and guard the rest of the pack. And tore lumps out of freinds, and anyone that just decides to come in unanounced.

Dumb question for you electromagicians - On the rs232 to ttl converter, does the ground and vcc need to be connected? The converter plugs into the DB9 connector on the Roboteq. Like this one: https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.com%2Fulk%2Fitm%2F233257882314
The Arduino is externally powered by a 5v supply running to the usb B connector.
I'm held up on that until a new one comes in. The one I ordered is a male. I didn't notice the Roboteq was a male until I went to connect it. D'oh!
Puts the little mods i have done to shame lol, well done will..

Compared to buying in standardised parts that the manufacturers like sunrise or invacare do. And instead of big budgets and teams of advisers and outside experts he is just ONE guy doing the lot, BETTER with brushless, tubeless, lithium, fat tyres, 48V for efficiency and speed, and more with a development budget of a few s.

...RS232 signal voltage is very different to TTL.I just don't understand why it needs the 5v and ground connected to the Arduino unless it's for reference or powers the converter's processor itself.
...Whilst TTL ...RS-232 standard a logic high ('1') is represented by a negative voltage – anywhere from -3 to -25V – while a logic low ('0') transmits a positive voltage that can be anywhere from +3 to +25V
Hence the need for 5v ( or 3.3v) supply to the TTL side.range from 0 volts to 0.8 volts for a “low” logic state, and 2 volts to 5 volts for a “high” logic state
