Subject: [randrdesulfatorforum] Courtiestown PIC pulser

Hi,

I have one of the Courtiestown PIC pulsers that has worked flawlessly
for a couple of years.

.... until now that is!

I'm having problems with the FET drive section of the board, with Q2
and Q3 (NPN 2N3904) blowing, causing the FET to remain in continuous
conduction and blowing the fuse.

Any suggestions from here on what might be going on? (seems to be
related to amplitude)

Rod
