    FOG MACHINE PCB FAULTY

    Hi Kris, the rail with the diodes reads 12V to ground at heatsink tabs. I checked the voltage from the striped end of the diodes to the transistors and I am getting 12V on the right hand leg of the top diode and 12V at the left hand leg of the bottom diode. From the diodes to ground I'm getting...

    FOG MACHINE PCB FAULTY

    The non-valid like before was probably a picture I deleted because of poor quality. Just let me know what you want me to check next and I'll get the results back to you.

    Hi Kris, I hope this helps. The picture is not the best quality. http://www.4shared.com/download/vxsTdghP/Antari_M5_Main_PCB_Relay_Socke.jpg?tsid=20130717-062333-2916cf8d

    FOG MACHINE PCB FAULTY

    Hi Steve, I believe the issue is between the voltage regulators and the relays. You're the experts.

    FOG MACHINE PCB FAULTY

    I'm assuming that it's the inner relay alone that I'm hearing as I'm getting 110V at the pump terminals and 0V at the heater terminal. http://www.4shared.com/download/BV2LtshT/Antari_M5_Main_PCB__Labelled__.jpg?tsid=20130716-044434-5bb026e7

    FOG MACHINE PCB FAULTY

    Hi Steve, the machine is fairly straightforward. 110V in to power the pcb and there are two 110V outputs controlled by the relays. The outer relay feeds the heater coil via the 110V outputs located next the the 110V inputs. The inner relay sends 110V to the pump via the 110V output located above...

    FOG MACHINE PCB FAULTY

    Hi Steve, sorry about the wrong reading. That was input voltage on the LM7812 I'm getting the correct reading, 12V at output.

    FOG MACHINE PCB FAULTY

    Hi Steve, I'm not too sure of the exact names for the parts. I just included links to photos of both front and back.

    FOG MACHINE PCB FAULTY

    Hi guys, sorry for the late reply. I did some poking around and here are the results. KrisBlueNZ, I measured the voltage at both relays and I'm getting 12V at the inner relay (this one drives the pump) and 0V at the outer relay. There are two regulators, LM7805 and LM7812, on the upper right...

    FOG MACHINE PCB FAULTY

    Hi *steve*, when I power up the pcb I do hear the click from the relay but there are two relays on the pcb so I'm not sure if it's only one or both that are clicking on. I'm not sure (not too versed in tracing pcb's etc.) but I think one relay switches the voltage to send 110V to the heating...

    FOG MACHINE PCB FAULTY

    Hi, I'm having an issue with a fog machine not outputting 110V to the heating element. I'm not sure if it's a defective relay or another part. Any help will be appreciated.

    PCB not functioning

    By the way, is this a decent isolation transformer to buy to test these types of pcb's?

    PCB not functioning

    Hi Kris, thanks for the detailed reply. As it stands right now, I'm down to only one more defective board. I repaired the second problematic unit but have not re-assembled it as yet so I have this working board available for comparison. The repaired board was powering up with the Green LED...

    PCB not functioning

    Hi guys, sorry for the delay but I was in the island of Tobago for one week then, when I got back, got the flu. Here are the results as requested. I replaced LP2954 with LM7805 as this was defective. I hope this would not affect the test results. I re-tested both U3's again in the working unit...

    PCB not functioning

    OK. So far, test to see if the flash rate varies with the different U3's in the working unit. Then short pin 12 on U3 socket on both pcb's to ground and check intensity. It should be the same intensity, right? On the issue of testing the capacitor, I can't check the drop on the faulty pcb...

    PCB not functioning

    Hi QC, I pulled the possibly defective U3 from the defective pcb (board # 1) and installed it in the working pcb and.......the lamp flashed!!! But!!!!.......it flashed really, really dim. I changed out the lamp with a new lamp and the result was the same, dim flashing. I then changed back the...
