Nothing special about this Monte. No SS, no rare options just a super sweet car to drive and take me back to the good old days!

I get alternators my parts guy calls the swamp buggy units. One wire and done, as long as you wire the big fatty on the post on the rear of the unit directly to the battery. Never been a fan of amp gauges. Even my restored 70 SS454 Chevelle is not wired for the factory amp gauge.

To the best of my knowledge I didn't melt any wiring but I sure did fry some electrical components. While I'd like the amp meter to work I can live without & if I can figure it out always mount a remote voltage gauge. Losing the other items is a killer, especially since most were brand new, like the trunk latch, & stereo. But by far the biggest loss was the tach. I really don't want to pull the dash again. I keep hoping since the distributor was replaced & upgraded & switching the alternator from a 3 wire to single wire and removing the voltage regulator that maybe the tachs still good & I just have something miss wired or not connected. Trying to look at the wiring diagram is extremely difficult & confusing. For now the cars just sitting as I've found it's not a good ideal to work on it when your in a bad mood.

Now if i understood correctly you said you have a 72. My understanding is in 72 the voltage regulator was internal. Now I could be wrong and miss understood the person. I know my 70 had an external voltage regulator which was removed for a one wire alternator which was then wired up as a three wire alternator. My 72 was brought as a roller but there was no regulator on the core support nor the firewall. If the battery leaked that sounds like the alternator was over charging the system to me. Not sure on what tach you have but if its the stock gauges you could have burn out the PCB on the cluster. There is fuseable links built into the harness which is supposed to burn out before any damage is done to the electrical devices. I've re-wired cars, moved cars over to 1 wire alternators then convert them to three wire as there is an internal regulator that you can access by removing a plug.

My 72 was externally regulated. I swapped to a 1 wire setup a long time ago and have had no issues. Those stupid external regulators fail pretty consistently and always at the wrong time. Those of you who know me know I drive my car often. I cannot have an unreliable externally regulated charging system.

There is a ton of information here on the site. by asking questions here and all over the internet. Many of us here have learned by doing. Never be afraid to try to fix something yourself, that is how you learn. The more you learn, the easier things will bet to be to fix in other areas of the car. A lot of things in troubleshooting a problem is pure logic. The more you can repair yourself the more money you will have to spend on other areas of the car. When you get frustrated, take a break.... or throw a wrench across the garage (just don't let the Monte, a human or another vehicle be in the path of the flying wrench. Sometimes adult beverages help in repairs but not always.

Tom, no need to be upset just yet. Let's think about this in small portions rather than a big problem. I assume you made it home in the car okay? Are you only missing the tach, stereo, trunk pop, and ammeter? If that is the case you can tackle one at a time. The stereo issue may simply be a blown fuse. The tach and ammeter may be related, so ask yourself if the tach and ammeter were working up until the car died. The ammeter feeds off the voltage regulator, and if you swapped to a 1 wire it may not work if I am not mistaken. The tach feeds from your distributor and you may very well have neglected to install the feed wire on the new distributor correctly. Retrace your steps there for starters.
I am not familiar with the trunk pop system so I cannot steer you in the right direction there.
Trust me when I say I love working on cars too, but have had many, many days of frustration while troubleshooting various issues. I don't like venturing behind the dash either, however had done it so many times out of necessity I could write a book. Ugh. My advice to you is step back, take a deep breath, and just think about what you have and decide the best first step. Like Rob said, there is a wealth of knowledge here on the site. All you have to do is ask.
