Hi all
Thought I would start a topic that something we did, .....WHICH was not such a good idea.
I'll start the ball rolling with the following mistake ..........
I'm wiring up my Tug electronics using the theory gained from 45 years as an electrician. Earth everything back to one point. Keep wires tidy and out of the way. Make access easy for repairs.
Presented with two motors and a bow thruster with their matching speed controllers, I started assembly.
I ran earth wires from the prop shafts to the motor housings and to one terminal of the motor armature. I then wired the Speed controller neutrals to earth through some ten amp fuses. (with me so far !!)
When the fuses blew for the 5th time, it occurred to me that something was not right !!
I have now rewired the speed controller neutrals to the motors and removed my lovely earth wires, except to the prop shafts. It now works as it should, and I have been suitably chastised.
Has anyone else got a useful tip or two to help us amateur's along the tricky road to boat building :)
Cheers...Ken
