Alternator wiring - Ford 2G, advice required please!

I'm looking to wire in my alternator I've identified the alternator as a Ford 2G. Its on a Ford 302 V8 - identified from this link http://fordfuelinjection.com/?p=63

Trouble is, I don't have the right connectors & I dont' really understand this wiring diagram...... what does 'hot in run' mean?? Is this a ballast resistor & if so what sort???

Is there a source in the UK for these connectors??

What type of 'fused link' should I use??

Thanks in advance, & Any advice gratefully received! Rescued attachment 2G-ALT_wiring.gif

suspect its an americanism for live with ignition on or engine running, most charge warning systems are ignition controlled







A pint for the gent and a white wine/fruit based drink for the lady. Those are the rules

a photo of the backside ofthe alternator would help. most likely it will be similarto one we can get overthis side of the pond and may even have labelled tereminals.

alternator warning

just a word of warning about these alternators, i have gone through 5 of these type on my mustangs in about 6 years. everything from bearings going, regulators blowing apart, regulators failing allowing 18v, and at the weekend the internals where the black/orange wires (to bat) come out of the alt burn out leaving a pile of ash inside the alt .
luckly it never spread setting the car on fire
take my lead and fit a different type of alternator

mfp,

thanks for the info, if I get a load of trouble with this alt I'll probably follow your lead & fit something more modern.

Since posting I've learned that a 'fusible link' is essential for the safe operation of these units, have you had to replace a fusible link in your setup?
