Triple checked the cam sensor before first start...... it idles nice and if you build rpms slowly, like normal driving, it's fine. But when you abruptly give it throttle, off idle, in stead of quickly revving up, it falls on its face for a second. Then revs up. If you bring revs up to close to 3000 then quickly apply throttle it reacts normally.

Plan on swapping my good alt on tomorrow and installing the in line light on brown wire.

Don't install the inline light at first. Try with the brown wire as normal and see if it charges

If it has a cat convertor...it may be melted/clogged causing off idle bog. Seen a couple like that. Gutted them...all was well.

No cat, single 3 inch exhaust, will eventually switch to dual 2.5

Update, swapped in my good alt and bingo, 14.5 volts. It also cured the bog problem!!!! Still no dash volt light but have a digital gauge Mark put in the lowest left idiot light spot, really like that so will be doing the same on other car.

I checked in my car where everything seems to work correctly and only 5 volts go to that brown wire and for some reason this car pushes 12 volts on this one so I did put a 194 bulb in line cuz it didn't want to smoke this alternator. Key on, engine off it still does not light that bulb up but everything is working as it should so I'm going to leave well enough alone.

Strange on that not lighting.  Last car I did that to was a digital dash car.  I remember it working, but, who knows?  LOL, as long as it charges, all is good.  Glad that fixed the bog.  Wonder if the battery is weak?  I saw one running in the tens with a bum alternator, but it had a freshly charged battery. 

When things work and problems disappear, it leaves a great feeling!

Pretty sure I have always seen around 12v on the brown wire.  think about it.  Not enuf resistance in a bulb to drop voltage very much, but it saves the diodes some way.

Yes it's a great feeling! Hard to believe how much better it runs from 12.5 volts to 14.5 volts....like a different car!!

Brad and Nocooler made the call, I was very skeptical 2 volts could do that but that was it!!

Steve, if you haven't done so...clean the grounds. I did mine every spring. I also replaced the negative and positive battery cable. I never had any electrical issues. As wire gets older...it builds up resistance...a nd if the grounds aren't perfect...you'll run into all kinds of issues.

P.S. Steve's the electrical wizard. He might be able to connect the dots as to why low voltage could cause a stumble. I just know it can, cuz I ran into that with a couple of TR's. Not very scientific...s orry.

Steve...does John Spina not sell a 'special' bulb for the alternator light. Think it was to keep the alternator charging?

You have to be beyond anal with these cars and incredibly patient. I always had the patience for my GN...but very little for humans.

Pretty sure he is sold out of these long ago Brad. I was able to pick one up after posting a wanted ad for it on the forum.

he had an alternator fix and may have had the socket with the resistor in it...Casper's seems to be moving away from buicks

I use to do group orders, and I think I ordered a few of them with some other stuff from John.

John Spina offers an upgraded flex board ribbon for your instrument housing which eliminates the need for the resistor bulb.
You can replace this on your own or just send in for the entire assembly to be rebuilt / upgraded

Must have a college student editing for him.  Full Proof, In Opt....

But, that is actually not a bad product for these old cars!
