I've got a stock 55amp alternator on the way so what stuff can I keep from the t1 generator setup and what needs to be changed?

get a billet oil filler, much easier than swapping over your old one.

Ruckus,
I put a post up about my whole schmozzle changing from gen to alt.

Called "Alternator Conversion on Klaus" in Tech Mods.

Is the 55Amp an internally regulated one? This will make a difference if it isn't. An easy way to tell is the externally regulated ones have a three prong plug on top. Most shops don't sell these Alts.

Enjoy

the three pronged alternators are just the factory ext regulated kind fitted from late 73 to early 75 and wernt sold as an aftermarket item
alll the kits u buy are the aftermarket int reg'd type
if u get a 3 pronged one its just one someone has pulled of a 74 bug

Thanks guys. Here's a pic of the alt:



Looks like I have to take the regulator off? Do I just make up a plate to cover it up? Also it's a 50, not a 55 is that going to be much of a problem?


Thanks heaps Ctefeh. Forgot about how good that thread was! Bit daunting though.

Ruckus,
I'll send you an email with two piccies of the regulator you need later tonight.
Don't hack wires until you get one.
Funnily enough I'm helping a guy out right now with the same alt, so I'll pass on the details of what we will have done to hook it up correctly.

Regards
Ctefeh

Ruckus,
The fella got given a two prong solid state Bosch regulator. Given Joel says it's all you need, what I did was re-use the brown and green from the gennie harness.

Terminal D- on alt to old brown, anchored at the old earth point where the regulator was.

Terminal D+ got a red wire we pulled over the top of the
original harness to the D+ terminal on the reg. This got a piggy back terminal at the regulator for the blue idiot light feed.

Terminal DF on the alt got a green wire to hook up to the original harness and got connected to DF on the reg.

DF and D+ are marked on the alt and new reg.
Someone before me has run an extra wire from the starter/battery hookup to the fat red lead of the main harness, so all I did was connect the B+ genny lead to the alt and butt connected to the battery+ feed wire that usually goes to the genny regulator.

Fingers crossed! Haven't started the donk yet as I am rebuilding his loom because it got chopped up extremely badly.

I'll post up when I see that the alt/reg combo is doing it's job.

The fella was told a new VW one would cost $200+ and have to come from the US:repuke

So where the hell do I find a Bosch two-prong solid state regulator (if that's what I need with my alt)?

most of the old H series holdens that run alternators have them and probably early commodores too
not a ford man so wouldnt know about them sure but i'd think they;re the same
so any wreckers should be able to sell u one

surely someone on the forum has one fitted that can show what they look like

Ruckus,
This is upside down Miss Pat. Green on Gen to green on regulator (DF), that black/white wire joins to a red (not long enough) and goes to D+. Also, the blue idiot feed is crimped into the black/white spade.

Brown wire comes from Alt D- terminal and joins the former brown gennie earth. Not really necessary but you never know.

Didn't manage to fire it last night, replacing the two engine bay seals took a long time and some claret shed to boot.


Enjoy
Ctefeh
