Well, I was hooking up my KY11-LB front panel to the machine I have moved into a BA11-K,
and after testing it several times, I saw a (not very big) flash from near the PSU and the
machine quit working. I inspected the power supply modules (two H7441 regulators and one
H745) and it wasn???t fuses, so I am baffled as to what happened.
I was SOOOO close too, I had got the front panel lights working, the RUN light flashed on
power up like it should have, then I realized the power switch was on backwards, cause
when you set it from DC OFF to POWER ON (or whatever, this is off the top of my head) it
would turn off. I switched the leads, then that???s when it popped.
I had the leads connected to J3 on the power distribution portion of the power supply (the
module that has the power cord attached to it)
I hope there???s someone on here who can help me, I???m good with computers, but I???m not
an electrical engineer, so I???m lost!
Thanks!
