I bought this Chinese made step up transformer to run some 220v appliances. Some of the wires were brittle and broke off. I attempted to improve some of the wiring with spade terminals and heatshrink tubing as the wires were just soldered straight to the connectors. Any advice on how to rewire the broken wires on this step up transformer? I'm unsure how to go about rewiring this to a better safe working condition.

 

It looks like you are in the right track, therefore, no suggestions are forthcoming.

 

Bit of a job to see all connections clearly, but it appears the windings are/were not terminated that well, some kind of solid anchoring for the ends of the windings is preferable.

 

What would help the TS is to trace out the several windings on the transformer. I did notsee much that made any sense at all.
Was this transformer purchased new?? Or used, from a prior owner??Broken off connections seldom happen for no reason, and so with the very views it is not possible to really understand what is present.
There is a circuit board with two wires soldered to it and no hint of how that relates to anything.

 

The picture suggests the exit-ing wiring is soldered direct to the winding ends. They normally would go to some form of fixed termination point Make up some form of fixed termination point, also, why are the lamination bolts removed?

 

Yes Max. My guess is that this is not a first owner situation. Like when you get called to fix a CNC machine because the first four who worked on it could not repair it.
