hey i have a question about wiring up an alternator on my 350 i have the lead going from the back to the pos. batt. terminal but the two prong plug where does that run to?...i have a little black box which is not hooked up laying in trunk from last owner. the alternator was never hooked up on the car can anyone point me in the right direction i dont understand the wiring diagrams so there no real help thanks again for your help!!!
Need to know what type of alternator,,,Internal regulated,,or external regulated.
Also,,what type of car,,,how is it wired??
Like denny say's,,,pics are best.
1969 chevy nova 350 cid ( 1974 lm-1 ) ok i found a little info it looks like the external voltage regulator isnt hooked up..with the alternator not being wired at all and the voltage regulator not being hooked up would that cause poor voltage threw out the car because dash componets work ( head lights, wipers dash lights, no gauges hooked up yet ) but rear lights dont work. front parking/turn signals dont work..the alternator is a three wire acdelco which i would assume already has a voltage regulator?? anyways i hope this helps pictures are kinda of out of the question digital camara had a run in with a 3yr old sorry but please any info would certainly help!!!
Im gonna guess u need a external reg. which should wire up I from ignition with 6or 8 volt resistor so it wont burn up the coil and it will shut off with the key. A from batt. pos. S from stator F from field. alt. has A S F on back reg. has I A S F. Hope this makes some sense its as simple as I can make it.
a few more questions but other then your diagrams which are very helpful thanks i found another but anyways the two prong plug for the back of the alternator has of course two wires 1 blue 1 white im sure i could figure it out but ill ask anyway which is the field wire? also there is a brown and a red wire im going to assume these are for guage and dummy light? thanks again hopefully ill have this taken care of tomorrow any finally drive this thing for the first time.. : )
