my paragon has a new altek MPU and new Rottendog rectifier board. I was playing a game the other night and all solenoids quit working. MPU boots, displays works, sounds works, and I can start a game. Checked voltages on rectifier board test points and at J1 pin 6. Both register 43 volts. Micro volts registered at the solenoids on playfield and at the playfield fuse. Fuse under playfield is good. No continuity from J1 pin 6 to fuse under playfield. So perhaps a short in the wiring?

The other troubling thing is the F5 fuse on the rectifier board is getting so hot you cannot touch it. You can smell the heat coming off the fuse, and it appears the fuse holder has melted or bubbled where it connects to the board. The fuse, however, does not blow. I have never noticed this before the issue with the solenoids.

Thank you for the reply. I found the problem, actually two issues causing the problem. The bottom left flipper coil plastic that the lugs is on was broken. Almost impossible to tell since the wiring to the lugs was well soldered. The fuse holder was needed t be replaced. Back in business and working properly.

I replaced the the burned/charred fuse clip at f5 on the rectifier board and it seems to have reduced the heat somewhat for now.
