they were 2w, and I found 5w online. I measured the resistance in the circuit of all 5 of 67-71 (the others ok) and found 36.6ohm. working backwards using ohms law and algebra, that works out to 180ohms.
So I call PPS and talk to 'Marty Rhett' ask him the value of R67-71 he comes back with 180ohm, 2w, 5%. Am I good or what.
Apparently, the dog killed it. water dish was nearby, it got spilled, was covered in fur from where he laid for the last year and a half, wet fur on output, ran over, popped the 10A fuse leading to the inverter section. ITs soldered to the board, so I have a ACG fuse holder, a soldering gun, some fuses, gonna make it a user servicable item.
Since I was dealing with LOTS of DC, I tested this thing using the old rheostat trick.
Now who here has a bad 73xx series? Send em in...
PPS wont release the schematic or give much help other than identifying parts, but I got this pretty well traced out.
Since I am no longer using the battery charge section of the 6330 in the winnie, when I pop this in, the 6330 will be available...any interest?
