i drive a 1994 sentra 1.6L 5-speed with about 133k miles on it. mechanically this car is in immaculate condition, averaging 32 mpg. there seem to be some pretty screwey electrical problems, though. it seems that if i shift a little rough, all the electrical sytems in the car will shut off or dim, save the alternator. the radio will shut off, the headlights and dashboard lights will dim, a clicking noise will come from the dashboard along with the "emergency brake engaged" light, and there will be a slight drop in RPMs, not noticable unless you actually pay attention to it. after this happens once, it will continue to happen until i turn the car off for at least 10 minutes, and is especially prone to this after i get off the highway or come down from a high speed (usually over 50 mph will do it). i ran an alternator check, and it doesnt seem to have anything to do with it. i plan on checking for frayed/burnt/loose wires and grounds this week, but i am curious to know if there are any voltage regulators anythere besides inside the alternator that i have overlooked that might have anything to do with this problem? any help with this would be much, much appreciated.

 

There are no other voltage regulators other that in your alternator but of course there is alot of electrical connections to check out. The first thing I would do is check the connections on and around the battery and the engine ground.

 

Have you been able to fix or locate the problem???

i have a 94 sentra also and seem to be having a similar problem. mine is auto but i seem to alwyas have the check battery light come on after i've been driving for a while. if i turn off the car and wait like 10 minutes it will turn off when i start driving again. my alt. and battery are fine but i also have the dimming of the lights, especially at stop lights at night when the head lights are turned on...

 

coming back from the dead but is there a voltage regulator outside of the alternator??????? I seem to think there is for some reason! Any help would be great. Having same issue with 98 Sentra GXE. Battery and Brake light come on together so I replaced alternator, fixed the problem for 6 months now its back? Bad alternator or is there a voltage regulator somewhere I have been overlooking?

 

bump really need to know its pissing me off,
