Yep nice and "stiffy" heheh.. Tried to keep all the AC lines crossin over to their own bundle, and keeping any of the bundles away from the top center screw hole (did I tell ya about the time when I didn't pay close attention to that? It was on a 700 and I had the 4 "black" fuses to show for it.. hehe)

Seems only right, brag and brag about em and no one knows till they hear em. Time to start an audition thread...

Yes Please! I'll take a PL 400 version of that? Get my father to demo one in place of one of his four 8 fin stock 400's he has now. Make him a believer..........

I would lend you Blackie but until she gets a new faceplate, she sort of stands out so it would be tough to sneak her into your Dad's rack LOL. Hopefully she will get full comped this year at some point from quasi

More than likely, Ron. I actually woke up at 5.. couldn't sleep.. then did half of the wires to the PL14.

Then I fell asleep in the chair.. hehe. Yep, tonight's the night.

Very cool Jer! I hear you about not being able to sleep... that's a nightly thing for me. I have been living on 3-4hrs sleep a day for well over a year now with my back. Just seems like I have a constant tightness in my lower back. I stretch, lift weights and stay pretty much active (just picked up 1/2 cord wood yesterday loaded and stacked that). Did a heavy workout yesterday in the snow. I ended up maxing at only 225lbs for 5 reps yesterday but I am just really getting back into powerlifting. Keep in mind that I weigh less then 150 but at that same body weight, I have benched 345 before in the past so I expect to be back up there sometime this Spring. I have to do more back excercises and perhaps see a doctor at some point this year

Whew..

Outputs in, Power and grounds done, outputs and whatnot routed... what a night.. :mrgreen:

Here's more eye candy for ya Ron! Man do I love that teflon 300c a/c wire... stays put.. easy to work with.. clean cuts... yeaah.. :thumbright:

This one is looking great - good job Jer. Question regarding the twisted wires - Did you twist them yourself and then add heat shrink? They did turn out nice.

FYI - I do have a stash of some 20 AWG twisted shielded cable and it is nice stuff. I could send some your way if you wanted.
 
Daggggnabit...

First time for me here... well it didn't quite go as planned. Strange thing... both pico fuses that carry both the + and - from the backplanes to the driver board are open on the left.. and one is open on the right. Measuring from ground to each on the load sides of the fuses and between + and - on the load side all checks out I think - no smoking gun shorts I can find anywhere. Double checked the transistors on the back wall.. nothing there either...

When I brought it up on the variac, I stopped the increase at 15 volts to check offset and for "obvious" bad indications. I did not see the current on the variac's indicator move one iota.. nothing out the ordinary so far...except 3 open fuses. Well, guess I am going to take the risk and see what is what here... again I am watching for excessive current and being VERY careful and slow when turning the voltage up...

dang.. well we will figure it out eh?? :mrgreen:
 
Shit happens man, hopefully if it eats anything it will just be a diode or two, something cheap LOL
 
That's why we bring em up on variacs and DBT's. Ya just never know.

Is that the blue and white stuff? Yeah, that's what I used for the AC running to the DCP.

OK.. SO... WE HAVE FOUND THE PROBLEM, AND IT IS US... well.. me.. heheh

Damnit... so what I did was temporarily jumper the fuses. Took it back up to 15 coming out of the caps and all seemed pretty ok there..

And then we went a lil higher.. And the ammeter said "ey!! something still isn't right here". So ok.. time to isolate it. I figure that the first best way to do that would be to power it back off, and then quickly check the rails to see if I see an abnormal drain on one or the other. The positive rail basically when kaputz... right back down to barely a volt. So hmm.. ok.. positive side - something aint right there.

Let's eyeball.. starting at the caps. Negative cap "check".. red dot facing the outside...

Positive cap??? Oh hell no... damn thing ... ass-backwards!!! That and I could hear it start to cook a little bit.

So... as I know WHO this is going to, we're not taking any chances on any component that could now be damaged, let alone the big ass power caps!! So... we gots some more coming. In the meantime, I'm going to swap out the suspects with the originals. Would like to see if anything else got toasted. I didn't reach much more than 40 volts so hopefully not. The current did not pass 3 amps (well maybe a lil more), so fingers crossed...

dadgumit.... Ron your bad luck bro.. heheh just messing with ya... anywhoo... time to do a cap swap here and see what's what..
