Previously posted in lighting forum: CHAUVET HURRICANE 1300 MOTHERBOARD ISSUES

Hey wizards, my apologies but I constantly post in the wrong forum group so I copied and pasted everything here. I'm stumped with 3 Chauvet Hurricane 1300 motherboards that have some issues that I have not been able to resolve so I thought I'd toss it out there to see if anyone's willing to help. I have one of these machines in storage waiting for repairs so if I could get one of these boards repaired I could set that one machine straight and possibly repair the other two boards to use as spares. One board has one particular problem and the other two boards have a different issue. On board no. 1, I did some re-touching of solder points and tested transistors, diodes etc and I am getting 120VAC out to the heater....sometimes. When I do get voltage out to the heater, (signaled by the green LED (D8) lighting up, the board is not cycling off the heater and I am not getting pump output via J3. Other times I'm hearing a distinctive clicking on the small black relay that feeds the pump and D8 flickers and flashes and voltage output drops out.

The other two boards have no 120VAC output to the heater and this output voltage to the heater block is normally fed via the larger relay. However, when a previously pre-heated block is connected to these boards, I do get pump output. If I can get them working, I'll be able to give a fresh life to the old Hurricane 1300 and have a couple spare boards to hold on to as parts. Plus of course I will learn a little more about their inner workings.

Hope I can get some help 😐😐

 I've resolved the issue with board No. 1 on these 3 motherboards. There was a broken solder trace on the motherboard that feeds the pump from the switch terminal and this was repaired and the board is now fully functional. So on to the other 2 motherboards.

As far as the other two motherboards are concerned, after testing both of them, the issue seems to be the 12VDC feed that triggers the relay to feed 120VAC to the heater. I applied 12VDC to the relay pins, bypassing the internal circuit feed and the motherboard functions as it should, the heater receives 120VAC via the relay so I just have to find the issue with the 12VDC trigger feed and I should resolve this issue but some input from you wizards as per testing, checking and metering would be greatly appreciated 😁😁
