Proprietary Hardware Conflict Two

Opting to keep the newer alternator from the Pearly, I went ahead and pulled it along with the one from the Silver. I found that there were a few differences... The ground connector, the spacing of the wing mounts, and the retention bolt diameter. Two of those could be overcome with some mild work, but the bolt hole was too far to go. Alas...


I connected the vapor canister between the manifold and the bypass valve. Now that I think about it, hooking up the purge solenoid might be a good idea... whoops. Here's the tee in white:


I've got to work out this mess. The wiring is disproportional and pretty battered.


Corded tires are corded. I put the new tires on the gold BBSs - RE-01Rs, 245/45/17.


Not for nothin', but headlights still fog.

Proprietary Hardware Conflict One

About two weeks ago, I replaced the serpentine belt that does, well, everything. In the process of tightening the belt, the adjustment bolt's head sheared off. It's an M16-1x90 with a shoulder cut under the head, about .360 wide by .270 diameter. I got a replacement from Mike's leftover stock and am back in business.

The DCCD controller cometh!

Of the many ways to install a DCCD controller in a car that's never had one before, the cheapest one involves a Velleman K8004 pulse width modulator. In simple terms, it takes a voltage signal and converts it to a constant voltage signal with varying pulse length.

The one that was in the car was in rough shape, so I picked up a fresh kit and soldered it up. The DCCD needs a 100Hz, 12V max signal. I got out the oscilloscope and adjusted the K8004's pots to a 0V minimum, 12V maximum, and 100Hz cycle.



This sequence shows the differential signal going from wide open to full lock:


I'll do a clean wire job and life will be good!

Tail happy!

Sunday, May 1, 2011:

For lack of knowing the consequences, I removed the shift surround from the console in order to install the leather shift boot that arrived recently. Naturally, the thumbwheel control for the DIY DCCD controller went with it.

This means that the center differential was completely open.

Needless to say, the back end was ten kinds of loose, and the SVX wound up on the grass at Cherry Valley twice. I pulled several large gobs of mud from one wheel.


Fortunately, the weather held out after the event, and I was able to get a wash in before the club meet.
