Sometimes talking it out...even alone :-) is the best remedy. Glad you found the problem!

Between the final transistor & The heat sink,
This is 12.33 +volts positive at the silver
Mount hole.. heat sink- is negative..
Add extra small piece of plastic..
Too one already there.this gets hot,
melts and shorts out causing no power
Too l.e.d. but inside fuse don't blow..johhn 938
