I'm with you there Joe. "shall not be tampered with, modified, or adjusted in any way (tampering includes drilling, cutting, machining, gluing, rewiring, disassembling, etc.) " Seems clear that disassembling for home repair makes your 884 a practice controller even if replacing with OEM parts. So we really might be better off getting a certified repair and saving a few bucks there if the competition supply is getting low.

Email response from IFI. So much for a certified repair

Chris,

If you have blown FET’s on your Victors, we generally don’t attempt to repair them. There are parts that have been compromised beyond just the FET’s and the cost becomes more to repair than to replace.

Has anyone actually successfully repaired one? It seems there are large copper busses in the middle of the board, which sink all the heat away when trying to clear the through-holes. After giving this a try, I now know why IFI doesn't bother repairing any.

Take a look at this http://www.chiefdelphi.com/forums/sh...4&postcount=31

What replacement FETs did you decide on?

Sandy,
It depends on the damage. If just one FET or two are bad, the cost to replace probably justifies the repair. Common thinking is that anything beyond a simple FET failure has likely stressed other components to the point of being unreliable in the future.
I have had success with larger Weller tips using Mike Betts' method. However, I heat only the pin and remove it when the solder melts. Then I clean the hole using solder sucker rather than the wick. If one of the holes is still clogged, then I simply heat the new transistor pin as I insert it.
