Bitza Mk2

Started thinking about wiring up Bitza Mk 2, specifically the Relay for the weapon.

Since it can share a common ground is there any reason why I simply can't connect the 2 negative terminals to each other, and then run only wire to my power terminal?

Got a problem with one of the drive motors, the motor stalls under little load and won't drive the robot. We've stripped and regressed the gearboxes and stopped the master gear that swaps the ratios from jumping out but still same problem.
If you turn the shaft one motor puts up more resistance than the other and both clutches are definitely locked.

Any ideas? These are Dewalt motors and boxes but not the monster ones.

Also can any one advise on the above query?

Cheers! Not long now!

Defiantly sounds like the clutch isn't locked up properly

If it were though I believe the motor would still spin.

Checked the speedo?

Directly connecting a power source, so no speedo.

First stage of the gearbox is probably mushed

No reason at all you can't join them up (apart from current handling which I am assuming you've got sorted)

@Jonny, The gearboxes seem fine, taken them apart a couple of times.

Current Handling? If you mean capabilities of the wire and relay itself they're rated well above what we'll likely draw.

Exactly what I meant, current handling, current carrying capacity, current rating................all the same stuff.
