May 31, 2013 Followup from the Pelican Staff: Sounds like a faulty alternator to me. Do you know what wattage the Subie idiot light is? Wiring of 3-prong brake light switches '70 and later. June 7, 2011 Followup from the Pelican Staff: I don't have wiring for your vehicle. I sure would hate to have to do that alternator again. You will want to check charging system voltage and current to confirm the alternator is faulty. If this test puts the light out, then the alternator is good, and the trouble is elsewhere.

When the battery problems started my partner removed something from fusebox thinking it would help but now i cant see how fast im going or mileage or battery lights or pi ture on dash of car that tells me if lights gone or doors open. If the alternator light is not coming on at start, then it sounds like it might be an internal diode problem. You can load test the system as described below. This article explores some of the more common aspects of the circuits. Any thoughts December 23, 2012 Followup from the Pelican Staff: 10.
The voltage regulator is used to adjust the current flowing through the field windings the stationary outer windings of the generator. The battery is brand new, and while idling the alternator is charging to 13. April 11, 2015 Followup from the Pelican Staff: Current will be the indicator here, as voltage will increase slightly under load but current will increase greatly. I assume the lead from the light goes to the exciter circuit, but thought that the newer alts used residual magnatism to begin power generation as opposed to an exciter circuit. Today she took the car to the parts store and they tested the battery and alternator.

November 14, 2010 Followup from the Pelican Staff: I'm not sure.
I've not had any issues with the stock bosch until recently it is over charging and boiling the battery. Red light came on the other day, and so I replaced the alternator before I found this article. I can't tell you what it was though. The voltage numbers on D+ are too high. The other end of the field winding is also connected to ground at this point. On the end of the harness is a plastic rectangular plug that has four colored wires attached. If your plug on your Subaru harness is different, then this probably won't apply to you.
When the car is first started, there is no output from the alternator at either the B+ or D+ terminals. As far as the wattage goes, I don't think that matters. If one is very low compared to the others, it may be a cell which is dead or dying, as a faulty cell will try to take more and more charge and end up electrolysing the water in the cell converting it to oxygen and hydrogen, so it appears to evaporate. F on the alternator to F on the regulator. I am lost as to what to do first.
I thought I had my Bosch alternator book here at home, but I can't find it! Some suggest it is the alternator, some the voltage regulator. I am wondering if anyone has any suggestions for me- I have a '70 914-6 that when the headlights are on, they slightly dim and then brighten in about a 1-2 second cadence when driving along the road. The bottom line is that in order for your light to light, you must have a net imbalance in the outputs of the D+ and B+ sections of the alternator or between the D+ output and the battery voltage, which amounts to the same thing. I know it should be connected, but it's not. I have a 1994 325is the car is eating alternators. Like I said, the wiring I have only shows your vehicle having D+.
The lower set of diodes on current track 80 is common to both the D+ and B+ functions, and forms the ground return for both the B+ and D+ outputs. These plates are alternatively connected to the + or - side of the cell. I can not connect this wire to any point. June 1, 2011 Followup from the Pelican Staff: You'll need the circuit with the bulb to go to D+. I Have A 1974 Beetle within External Regulator Alternator Wiring Diagram over can be labelled with: put up by means of admin on June, 3 2015.
Jay Jay, thanks for the info and good wishes on this project. Battery new and takes charge fine. I was hoping that maybe someone here has already done this with the same engine that I have. You have 10 volts at the alternator B+? This means that there is +12 volts on one side of the charge warning lamp, and the other side of the lamp is grounded through the alternator field winding. Bothe the 5 am and 7. When turn signals or hazards are activated the generator light comes on dim and the flasher relay buzzes but no indicators on dash or at external light. It can create a voltage spike that will damage control modules.
