anyone converted from external regulator to internally regulated alternator?
I'm getting fluctuating readings out of my alternator -- ranging from 15 to 18 volts on a fully charged battery-- it stays at 18 volts for a good half hour after start up before dropping down to around 15 volts. I'm assuming either the alternator or the regulator. It's fluctuating enough that the amp/hu in the back are going into protect mode due to overvoltge.
I'm thinking of going with a newer, internally regulated alternator. Anyone done this before? I know it's fairly trivial-- I found these guys on the web, looks like this just makes the job (electrically) a plug and play:

Any thoughts on this before I get involved would be appreciated.

Go to the auto parts store and buy a 20 dollar new Wells VR and plug it in and bolt it down and keep driving your car.

Regulator
I changed over to an internal regulator system on my 66 and 68. The wiring was easy as plug and play. No problems for the past 15 years. I also upgraded to a 100 amp. system. The alts. are all over the place and are inexpensive. Jerry

my understanding is that you leave the regulator in, and bypass it by either jumping some of the wires or plugging in an aftermarket adapter harness (but I've been wrong before)

I did the conversion on a 67 modified car. Used the pigtail from harness to alternator, then I took a junk voltage regulator and jumpered the wires inside the cover, and plugged the wiring harness into the regulator instead of using the little rubber adapter. Did that just so it looks better.

I used the LectricLimited connectors as shown above when I installed my 72amp internally regulated alternator. I installed an 8ga wire parallel to the factory wire from the alternator to the horn relay. I was a little worried about the normal 10 ga wire. Wrapped it up; not noticeable. Not sure it's really necessary with that amount of amp increase, but it made me feel better. .

Excellent idea!! Very stealthy. In case anyone else wants to try this, below picture shows how the Lectric Ltd adapter is wired.

I used a 76 Chevy alt. and Connected the BAT. terminal on the alt to one of the spade terminals on the alt. (not the idiot light terminal)
Iv'e done it on two of my cars and never had any problems.
I use a voltage gauge on both cars and have not noticed any excess voltage or charging.
