ALL Practical apart from a paper exercise on moding a 24v dc circuit!
First = wire a Wieland Plug on each end of a piece of 17core cable
crimps and all! then connnect to sockets and check continuity 50mins to complete! i did 48mins in slow time!
second = wire a 3 phase star delta motor! using isolation procedure etc and testing for results. IR and CR tests! then rewire to make spin other way!
third = 110v - 24v DC system (relays and the like) fault find 3 problems = 1) Push Button contactor used was NC but the wiring diagram said should have been NO.. 2) Blown Indicator Lamp 3) incorrect wiring configure in panel move 1 cable to different terminal.
fourth (paper exercise) how to make the green light on the circuit go off after 5 seconds with out interfering with the rest of the circuit! A= Install a Time Delayed Contactor before the lamp etc..!
this was the Electrical Test for Nissan by the way!
