• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

electromechanics! help me!

Some people hook up a battery charger to sensitive electronics...not a good idea. This type of power has a ton of ripple or AC component associated with it and its hell on the sensitive stuff. A battery has absolutely no AC component and it's great for this application.

If the +12 volts is getting clipped somewhere in the harness then powering it remotely with an external source will let you know. The only other way to do it is unplug a bunch of stuff including the PCM and start testing your power/reference wires for resistance to ground. Do you have a pin-out of the PCM?

Did you verify that the 96 Lumina harness would have the pins in the correct places for the 98 GTP OSID?

I went by the information provided: 98 LTZ harness and a 98 PCM. The schematics for the LTZ are the same as the 98 Grand Prix VIN 1.

Good point though.
 
Wow, thought I had read 96 lumina earlier. See...the coke and water are helping. Couldn't even see straight this morning.
 
Every time you get into a thread after me I get nervous. That's how good you are. LOL
Once in a blue moon I get ya. So --- gotcha!
 


It's ok, I'm requesting schematics in two other threads. That'll keep ya busy for a minute. And.. I'm just as human as the next guy.. I just post a lot. Nothing to be worried about. lol
