Taking the head and tiller appart, reverse engineering the electronics …
↓↓↓ Complete description, time index and links below ↓↓↓
So I bought a pair of Haswing Protruar 2.0 trolling motors. We’ve already unboxed them and ran the first tests (link below). Today we tear the head and tiller of one down and reverse engineer it, focusing on the wiring and the throttle control.
We start by taking apart the head and tiller. Then we disconnect the throttle wiring and mesure the resistances, voltages and currents around the throttle potentiometer. Finally we check if battery minus is digital ground (which it isn’t).
00:00 Intro – tearing down the head and tiller
00:35 Teardown I – mechanical (lots of self-tapping screws)
11:36 Teardown II – wiring (all soldered and heat shrank)
15:34 Wiring diagram – 4 components and 15 wires
16:53 Resistances – of the throttle potentiometer assembly
20:19 Voltages – at the throttle potentiometer assembly
27:29 Currents – out of the throttle potentiometer wiper
29:08 Ground(s) – battery minus is not controller ground!
33:04 Wrap-up – let’s tear it down, bye
