If I switch to the internally regulated alternator what other changes are required? I saw something fora 240z but does anyone have what needs to be changed for a 76 280Z 2+2? Also, what year 280ZX alternator should I be looking to get? Part? Thanks for all the help.

I installed a new volotage regulator about 3 months ago and then again about 2 days ago. Neither fixed the problem. I have considered the internally regulated alternator but feel that I have something else going on. Not sure if wiring or grounding would cause over voltage. I also put a new alternator on twice in 1 year and a new battery. The battery was less than a year old. Just not sure of what else would cause the added voltage issue. I am leaning torward wiring but again not a real electical person.

Thanks. I am not that familiar with the ignition system. A novice at best. Just to clarify a few things. The car is stalling sometimes 1 mile from the house and some times 20 miles after driving. Yes the car will start normally about 20-30 minutes afterwards without a jump. I assume that I have a charging problem due to the fact that my voltage at the battery is getting over 17V at rpms. The radio is shutting off. I thought that this could be shutting down the ignition module. Again a novice at best. Maybe moe than one problem.

Great. I will try. Electrical stuff is not my expertese. I have pulled the FSM and will give it a shot. Thanks.

Nobody have anything to add? I see a lot of viewings but no responses. I can not think of anything else that would cause this issue.

I am new to this forum and have been using another for this topic. The other forum has and is doing a great job but thought I would try here as well. I have owned my 76 280Z for about 1 year and driving it short distances, 6 miles, daily. About once every 3 weeks the car would stall during driving and after about 30 minutes would restart. I suspected rust in the gas tank and that might still be an issue; however, a new possible issue came to light. I installed a new radio in the car in December and noticed that at rpms around 1500 the radio would shut off. I tested the voltage at the battery and found at idle (1000 rpms) it was about 13.8V. Good. At 1500 rpms about 17V. Not good. About 3 months ago a mechanic had replaced the alternator, I also replaced the alternator about 8 months ago, a new voltage regulator and a new battery were also added about 3 months ago. After about 50 posts on the previous forum we decided to replace the voltage regulator again thinking maybe it was bad. I installed today and no improvement. Additional info; With the external voltage regulator unplugged I got 11.6V at battery regardless of the rpms. I beleive that this means that the alternator was not working. The car ran great around the neighborhood but I am guesing the battery would soon die. Any help would be appreciated.
