alternator pic needed

[Mat Big Hat]

can somebody take a quick digital pic of the back of their alternator?

mine needs replacing, and i want to use the proper external regulator type (cheap)

problem is that somebody rewired things so that they could use a lucas (internal regulator?)

so i'd really like to get a visual

tia!

Here are a few pictures of an old externally regulated alternator on my '72 (prior to making an upgrade to an internally regulated unit). You'll note that the external regulator has been removed, but the pictures were taken prior to removing the old alternator.

thx deesz!

lachlan also emailed me a pic, and it looks like his car doesn't have an "E" wire either

i guess they figured the alternator could ground on the engine bracket

Didn't much more than glance at this before but ....

That 'condenser' or 'noise suppressor' (really a capacitor) should have its pigtail connected to the B+ terminal and its body attached to the E terminal. Installed as in the photos it is at earth potential both sides and won't do diddly squat!

There should NOT be a wire from E to the car body. That should be done at the battery -ve terminal direct to the body AND to the top starter mount bolt.

You are right that the alternator earths through the mount bracket.
