Sorry guys, accidentally hit post while writing. Appreciate all the feedback guys. I didn't see any evidence of contact between the downpipe and a arm. Checked the exhaust bracket and its in really great shape. But, while under the car I found what could be a contact point from an exhaust...

Appreciate all the feedback guys. Checked the exhaust hanger and it's in great shape.

Thank you guys, really appreciate the feedback. I'll be checking these points this evening after work and will report back.

Thanks for reading, everyone. I need some help troubleshooting a hard contact "bang" noise when my 87 GN goes through a steep dip (for example a transition joint on the highway between bridge and pavement). It only happens when the car has 2 or more people. The noise sounds like it's metal on...

I apologize for the delayed response, Bob. I finally had time to pull the ECM and check connections and you were absolutely right. My cable was disconnected from the powerlogger bank. Now I can start educating myself on where this car needs to be. Thank you again, Bob.

Good morning Bob, and again, thank you very much for all your help. I'm located in Southeast Texas, almost two hours east of Houston. I've reached out to nearly all of our local reputable performance shops and none deal in turbo buicks. It looks like Houston will be my only option, which is...

Thank you Bob, I really appreciate it. The Scanmaster was working great for months after I bought the car and then it suddenly said "no data available" and completely shut down while I was driving. Is there a reason that powerlogger Scanmaster option would have suddenly reverted? Also, the...

Hoping to get some advice on troubleshooting my most recent issue with my 87 GN. On ignition my Scanmaster G immediately says "no data available" for just a moment and then goes completely black and remains that way. The process just repeats itself every time I fire up the car. I am running a...

Steve, I witnessed the bench test after having the alt rebuilt, and it was good to go. That's really what was throwing me off. Good battery, good alt, good wiring, good volts light. It wasn't until I questioned the internal regulator when I found the real issue. I think it would be wise for...

You were spot on. I tested all of my grounds and wiring, finally pulled the alt off and brought it back to the shop and had them make it self exciting and problem solved. It was the replacement regulator. And like you said, this issue is becoming more common. Really appreciate your help on this.

I appreciate the feedback. I'm going to bring the alternator back to the rebuilder, who has an extremely solid reputation in our area, and have him test it and test the input port. Is the Chinese regulators not compatible with turbo buicks or do you believe the alt is simply still bad? Thanks again.

Hello everyone, I've had my 1987 Grand National for about 8 months now and recently my volts light came on in the dash. I had the battery tested, it tested bad, bought a brand new battery, installed it, and same issue. Volts light still on. I started doing some testing with the multimeter and...

I hear you, I'm undecided on my interior speakers. For the deck, I'm going with the old Alpine 7618 with the aftermarket Bluetooth module and an Alpine 3331 EQ. Two Alpine 8" subs on the trunk deck. If you want to keep everything fairly stock, the Bluetooth amp option is a good idea, just need...

You got it, thank you.
