I have a small unit in the rear trunk pass. side behind tire well that I think is it. The PO has done a job on all the electrics on this 79. I just bought a new alt. ($120) and I dont want to screw it up. The Haynes book doesn't show me enough for me to understand
(can we say Forrest Gump)
Anyway, I have a connector with 2 holes (red wire and a green wire)there is also a black wire hanging.
I have the brown wire to the starter attached to the b+ post and there is a black with purple-I think this goes to the volt meter, but I don't know where to attach it.
any help will be appreciated<!-- google_ad_section_end -->

[FONT=Trebuchet MS, Verdana, Tahoma, Arial]<!-- google_ad_section_start -->Hi Bob... now what year is this? '79's and later have either a Bosch or Marelli alternator with an internal voltage regulator. Only two wires to this style alternator: heavy one to battery connection at the starter, and light one to the alt warning light (also supplies power to the v. reg)...
'78's had a strange (and problematic)Marelli unit with an external electronic regulator mounted in the trunk where you describe. What year is your car? A/C or no?
Is the alt you removed the same type as the one you are installing? Let us know,
Steve<!-- google_ad_section_end -->

[FONT=Trebuchet MS, Verdana, Tahoma, Arial]<!-- google_ad_section_start -->I have '79 and just went thru a bunch of *&^%$# getting mine to work again.

Let me cut to the chase... MAKE SURE YOUR GROUND STRAP behind the left rear wheel, between the trans and body, is CLEAN and TIGHT.

If you have any further problems... I have a great wiring diagram I can send you... (it doesn't MATCH my car exactly... but gives one an idea...)

Keep in touch, let us know how you do... Those two wires cannot be miss-wired and you shouldn't hurt anything.

[FONT=Trebuchet MS, Verdana, Tahoma, Arial]<!-- google_ad_section_start -->but through the years all sorts of things could have happened. I have an alt with an external voltage reg. the green wire going to it has been cut, another wire spliced to the cut end from the alt., but that wire is just hanging there. There was added on a small unit with the word "transpro" ,,a wire from that was connected to the center prong (this alt. has 3 prongs(excuse me, male connecters). I do have AC
The ground strap was cleaned and is connected well, did that during trans. rebuild
Just did some head work and am going out right now to fire (I hope) it up. I'll play with the different wires and see what happens and I'll let you know
First race is Sunday,,,sure would hate to miss it<!-- google_ad_section_end -->

[FONT=Trebuchet MS, Verdana, Tahoma, Arial]<!-- google_ad_section_start -->Also...

If yur not already doing so... get a DIGITAL VOM to read your voltages ACCURATELY.

One can be had at Harbor Frieght fo 6.99.

Placed across the battery you can then "see" all sorts of things. The exact voltage at rest, s/b 12.6vdc, at 1000 RPM, s/b 13.4vdc if the alternator and V/R are working properly...

Shouldn't drop more than 1.5vdc when cranking...

An analog meter makes it difficult, a digital makes it clear.

I spent 3 weeks trying to figure out a starting problem when I had a good battery, good alternator, and a good starter. Wiring and ignition switch OK.

Then I checked votages at rest and found that I had 12.05vdc at the engine and 12.5 at the battery. My digital VOM didn't show me the .45vdc difference due to the loosened ground strap... when I finally saw that with the digital VOM, I repaired the problem in 2 minutes.

Later,
