I am in the market for a new alternator for my 2.7l. I currently have a SEV Marchal. It is not working. The fan housing that I have is from a 2.2e. Any recommendations of an alternator that I can install? I know very little about alternators on 6 cylinders. Any advice is much appreciated. Cheap and reliable is a major plus.

Have the one you own rebuilt by someone who knows what they're doing. Not just fixed, but reconditioned. New brushes and such. Saves $

A rebuild should take a couple days. In the meantime, look for a spare to store away.

Agree.
Just got my back from being reconditioned/rebuilt/restored. Looks like brand new. Guy replaced diodes, brushes, bearings, seals, etc. |

Who does the rebuilds?
Also- can the alternator just be plugged into the relay board just like with the /4 engines? Or am I simplifying things too much. |

Our local battery shop does our starters and alternators. 2 day turnaround, $100-125 on average.

The early 911 alternators were externally regulated, just like the 914-4 alternator. You can use a stock relay board and the regulator mounted there, but you have to have the correct engine harness to hook up the regulator.
A better way is to buy a 911 SC or Carrera alternator. It has an internal regulator, and it is a direct bolt on to your engine. The only wires you need are the big heavy red one from the starter, and the blue one that hooks up to the alternator light. And yes, you can change a six alternator with the engine in the car. There is an article on this site that will explain how. |

If you're really going to get another one, I got one from RetroAutomotiveProducts
that's been fine for the last 5 years. They are 1 day shipping away from me so I may be biased. They have a store on Ebay but also a real phone number. RETRO-AUTOMOTIVE-PRODUCTS |

Though the internally regulated alternators may be simpler, I do like the ease of swapping out the externally regulated ones. Often, it is the regulator that goes south, so much easier to swap on the board rather than fighting to take the alternator out on a -6.

Many of the guys over on the bird say the externally regulated alternators have less issues than the internally regulated.
They figure the heat of the engine cooks the regulator. Most auto electric shops do just as good a job as the factory, you have to know your poop, but there's not much to them. I've replaced bearings in the T1 alternators, often that's all that is wrong with them. I replaced the bearings in the alternator of my bug. |

if you have an early fan housing the internal reg. alt will have pulley alignment issues. the later fan housings are machihed deeper to allow for the longer length..

I've been running an internally regulated alternator since 86 with no problems. I dumped the relay board and wired everything direct. My first motor back in 86 was a 2.7 with webers. After it died in 2000, due to pulled head studs, I swapped it with a 3.2. Unless your a concours weenie, I would dump the relay / regulator board. Besides the regulator the board powers the fuel pump, heater fan and rear window defogger.

(IMG:style_emoticons/default/agree.gif) Very important! Not a minor misalignment, it's close to 3/4" (IMG:style_emoticons/default/huh.gif) |

Does the same apply to a 2.4? My alt is shot and I've been putting off pulling the motor. I've also heard about the internal vs external regulator. Is it the same for a 2.4?
