5000CTC Not powering up

You really should be using the proper power supply.

The CTC is *very* fussy about getting the right voltage, and it needs a good solid 5A supply. The voltage it needs depends on the model, some of the earlier ones needed a higher voltage than some of the later ones.

If its not starting, you almost certainly don't have enough volts (some models may require as much as 5.7 V - AT THE TERMINALS ON THE CTC not on the output of the supply) - at 5A you need to allow for the losses due to cable resistance.

As to which model you have and what supply it needs, It Depends.

You really should be getting a replacement supply from Clipsal. If you use a generic, make sure it has appropriate safety ratings.

If you can't or won't get a proper supply, then if you can, wind up the input volts to about 5.2 to 5.5, and see if it starts. If it does, then it should have a 5.7 V input. In doing this experiment, don't put the input above 5.5V because thats the limit for the models that don't have the higher input. Be (a bit) like Elmer Fudd: Be Vewy vewy care-wfull when fiddling about like this.

(Why the high input, you might ask? Well as far as I can remember, some models have a big front end reverse polarity protection diode and this drops about 0.6 to 0.7 V.)
