Just knocked the psi whilst it was on and hot now it is not putting out ant voltage did i kill it. 240v getting to it but no 12v sc out.
yes mate the fuse is ok unfortunatelyThere looks like a fuse on the secondary. Have you tested it?
no way to test the windings either is there!well if its getting 240 volt in and nothings coming out the trannies had it
Disconnect the transformer and measure on ohms the coilsno way to test the windings either is there!
nothing on ac or dcjust use a voltage test on the 2 output wires from transformer going in to the board set meter on ac v
It did run my rust tank. Yes it's a old cb power supply.Then the transformer is duff. You might be lucky and be able to carefully peel off the insulation where the two secondary leads go into the transformer. They will be soldered onto the transformer wires normally. You may even find a thermal fuse in there that will be o/c.. You can replace it if it is faulty or bridge it to test the power supply. That's quite an old power supply looking at the round multi legged IC. You'd be lucky to find one of them now! You may be able to find a 22volt transformer, if not, a 24 volt is more common and if there's a zener in there, it should clamp it. What does it run?
Yes neon comes on I'll check the voltage across fuse later although I go 0Just as a double check. Does the neon come on? What is the AC voltage across the fuse (it should be zero).
