(1a) Nachos' bulkhead parallel bypass (1b) clean all terminals/connections including ground paths (check voltage drops on ALL points). (2) as said relay headlights/AC/heater to alt (3) as said if needed a better alt. I'm assuming the battery is in good shape

The best thing you can do is run a wire directly from the alternator + stud to the battery.(or to the starter relay) This will take a lot of load off of the bulkhead connector. With this mod, the alternator will be charging the battery directly, instead of having to go through the bulkhead twice. Is this just an extra wire added, or is there cutting of old wires involved? Will it work on a 68??

Is this just an extra wire added, or is there cutting of old wires involved? The MAD Electrical website has you cutting and splicing the factory wiring. You can read it here. http://www.madelectrical.com/electricaltech/amp-gauges.shtmlI'm not doing it exactly that way on my 68 Dart. I'm just going to keep the factory wiring intact but add the extra bypass wire. The bypass wire has a very low likelihood of shorting to ground but I'm still going to add a fusible like to it for my own piece of mind. I'll be using relays on the headlights and on the convertible top motor to take as much load off the bulkhead as possible. I already bypassed the AMP gauge and will run a volt gauge instead.

you can drop an 89 m-body alternator on it. 73 or 78 amps factory. fairly easy. Like this one? Amazon linky Robert

The 87 alternator does, but the factory changed the brackets when they went to the Denso in 88. I know when I put the Denso in my 87 M I used the 89 bracketry. I vaguely remember because that it was because the Denso didn't bolt in, but it's vague. The 87 alternator is the 78A unit, the 89 Denso is a 90A unit.

The next thing would be to add relays to the headlights. This will take even more load off of the bulkhead. It should also fix the problem of the lights dimming at idle. X2 Make sure you wire in a fusible link or at least a 20 amp in-line fuse at the starter relay or battery which ever you tap into. Also convert all bulbs inside and out to LED's as mentioned. If you are doing any dash work,replace the old bi-metal 5 volt limiter for the gauges with an electronic one. Another option is convert the ammeter gauge to read volts. Hope this helps.

Just curious if anyone has suggestions for charging system upgrades for my '73 Challenger that are basic & affordable parts swap-out mods? As far as I know, the setup now is all standard stuff w/ a generic parts store alternator. It depends on some stuff. How many amps do you need? Is it a single belt system running the water pump and alternator? Is the mechanical fuel pump still there or is it gone? The 60A Denso kit that I've sold for years is a very simple setup that works really well. It also is lighter and smaller than the factory alternator. I'm now switching my personal stuff over to low mount alternators since I'm EFI and don't have a fuel pump. I have low mount kits for 90A or 60A Denso alternators. Both would fit with plenty of room in a big block E body car. I doubt that you need 90A in your car so the 60A is probably the way to go.

more like https://www.autozone.com/batteries-start...763001_962401_0 odd that 89 shows different. It is still an m-body, but whatever. This is the standard dual field I was talking about. 87 fifth ave does it for me when I look it up.

In 88 the M bodies switched to Denso alternators
