Hi Clifford,

If you suspect that the RW wire link is missing, check the underside of the '808 ECU. It should be quite evident.

If that's not the issue with the communications, bear in mind that this can only work if the 12P firmware has been preloaded into the NVRAM.

Well made an adapter according to this website wiring of plcc to ostrich. Have tested each pin from ostrich straight through to the adapter but ostrich will not work, upload bin, set to bank 8 but pcm wont fire up, put a eeprom in the socket and pcm fires up straight away. So im out of ideas atm. h...

Yeah, it seems to be a PITA with the switchover with the S3 to VT. Like a Frankenstein setup! Correct, the service number is 16234531 - CJYN. Should I be using the VS ADX, XDF & BIN or the VT? Now I'm a little confused. I'm currently using the attached files and the car is running like a dog, b...

Well, it's about 6 months on now, and the new regulator seems to be content with its life, no repeat failure. So it's time to call it. The original regulator must have failed (shorted output transistor) of its own accord, and not due to the surprisingly low field coil resistance (which must therefor...

reading the first sentence in the NOTE part states it all, you only getting a V6 memcal that's reprogrammed to a V8. No ECU Included by the looks. Big rippoff at that price. So many people trying to cash in now days. Hmmm ... I don't think so, I think that their wording is just a bit sloppy. The ad...

Well, the white label on the PCM looks original, so I'd say what we have here is the marrying of a memcal-less '424 PCM, originally V8 CKUP, with a V6 memcal which has been reprogrammed with the CKUP firmware.

FWIW, the most common brand of connectors used in Commodores seems to have been (AFAICT) Yazaki, then AMP/Tyco as a distant second, then a sprinkling of others such as Sumitomo, Delphi/Aptiv, etc.

I really doubt there is a problem with the rotor. I used to always carry spare regulators due to the failure rate. They usually stop charging and the red light starts coming on but yours is another problen with it continuing to provide current to the rotor with the ign off. I had that once on my ow...

When I started this thread, I had a faulty alternator that had flattened my battery quick smart, despite the car being off (except for an initial 10 minutes or less during a short drive home). Finding that the regulator had a shorted transistor that drives the rotor field coil, and a resistance of o...

If you look on the P04 where the connector pins are soldiered in, pay close attention to the circles where the soldier goes. Some of them have some kind of markings, almost like telling that certain pins are special and have a different purpose. It's not clear what "markings" you are refe...
