Pspu-j702a power supply

Salutations Robert Isringhausen,

"Complete" FACTORY MANUALS (the real ones) can be quite pricy... but can be sourced by simply using those magic words in a WELL CONSTRUCTED search line on your favorite search engine... I actually highly recommend FACTORY MANUALS...

AND WORSE their availability fades just as the PARTS AVAILABILITY fades as the years go by... For 2006...
you may NOW have to settle for used.

I'm sure there are CD/DVD versions available... but I personally prefer paper (although I've been fully (& tediously) trained to use film, fiche... floppy, CD, DVD (etc.)and all that other jive...
nothing beats a good paper copy of schematics, wiring diagrams, operation schematics, component data sheets and CIRCUIT DESCRIPTIONS... (not to mention their "UPDATES"
(TECHNICAL SERVICE BULLETINS).

A FREE alternative... BBB Industries
(see below: registration is required)

I also highly recommend them... they are the absolute best source of technical information.

But once you pay their initial price ... you become acutely aware that dragging them into a greasy dirty job site is a terrible idea.

20 years ago when JAGUAR produced the last 6 liter V12
CABRIOLET XJS ... I decide I must have one...

Even back then (1995)... I think the over counter (discounted) price was well over $800 USA... (but they are a beautiful set of books... (and I ALWAYS treat them that way)).

Focus on the two resistors on the output side ( USB port)

either you use another power supply with the same voltage output and use it,

or have the output transistor on the primary side (SMPS) replaced.

go to the miller website and download the manual. the scematic is in the manual

It is about $80

It can be difficult to troubleshoot down to component level.

If you can get schmatics diagrams of the machine locate which CB is breaking and then locate what units it feeds, such as fuser or HV ,LV supply boards etc Disconnect the board(s) assigned to that breaker see if it trips

I removed all the screws from the back cover. Upon visual inspection of the power supply board, model # PSPU-J707A, I found electrolytic capacitors C233 and C234 to have bulging tops. Both caps are 10V 3300uf. I'm going to replace them and post the results.
