Connie: How can it take so long to do a simple alignment on an american sedan with standard rack-and-pinion steering and MacPherson struts When your garage is equipped with the proper Borg-Warner digital hydraulic radiometer?

Ronnie: Maybe because I was out back finishing a beer.

 

[laatsch55]

Thankls Joe.....makes sense now...

 

[laatsch55]

3 for 3....

 

[laatsch55]

Small snag, had to trim the IEC body....

 

[laatsch55]

All outputs in, didn't have to drill shit. oe they must have got better at that as time went on..

 

[laatsch55]

There's not supposed to be. This chassis was just built on the wrong day.

 

[laatsch55]

DCP wired in. Working on the new power switch.....requires another hole...as does the new meter range switch....always something...

 

[laatsch55]

That wasn't too bad. The original switches came as a unit. Just had to drill 2 new holes......and 4-40 stainless allen heads took care of the rest.....and had to file a relief for the toggle pin...

 

[laatsch55]

Meter wiring run...

 

[laatsch55]

Przem requsted the meters be disassembled and the inside of the glass cleaned. That has been done and the LED's themselves cleaned along with the red transparent strip between them...

 

[laatsch55]

Meter range switch wired and meter power wires run...

 

[laatsch55]

All we have left is to wire the board in. I'll do that in the morning....

 

[laatsch55]

Thank you Przem...we try....

Yes, those are the switches from Ed. The power switch is rated for 8 amps, the original was rated for 5. Paralleling the switch will help extend it's life. I have no idea where he got them, methinks he looked far and wide and bought them all when he found them...

This is looking real good Lee - nice job and good to see you back on the bench. Tight spaces are good for some things but not wiring. Wiring is an art form - one can present an argument for the tight space too.

Yeah - leave it to Przem to leave his nuts on the inside.

Thanks Dennis....what a lot of folks don't realize is just how neat wiring can be....until they've seen some of your work....which, by the way, we haven't seen for at least a year...

 

[laatsch55]

Board time....

 

[laatsch55]

Right side done...

 

[laatsch55]

Board wiring done, tie up a few loose ends then it's time to nut up and plug this F*&^%$ in!!


One thing I lack is a 240 volt variac, however it does go to 140, that should be enough for the board to regulate but maybe not enough for the DCP relays to click. It will tell me if I have problems before we go with the full 240.....

 

[laatsch55]

All fuses checked and in, board isolated, voltmeters hooked to the outputs, fingers crossed....

Very cool. If you find yourself in need of a step-up transformer, I think I can lay my hands on one for you. We permanently decommissioned a couple of dead heaters at work, and they were powered from step-down transformers. I know they were fed from 277 but I'm pretty sure it also has a 240v input tap and a 120v output. Wire it backwards and you've got 120 in and 240 or 277 out. Not sure the amperage offhand but the transformer itself is pretty close in size to a stock PL 700 transformer. Let me know if you need it, and I'll dig it out of the ceiling.

otherwise you could really cheat and use a couple of extension cords plugged into outlets fed from different buss lines in your breaker box. Hot to hot should give 240v. If you get 2 on the same buss, it'll be 0v. Thats not really a safe way to do it, but it does work in a pinch.
