New harness almost done...help!

[hazmatty3614]

69 Ghia Autostick coupe...

Everything is rewired on the car except for making the connections to the new fuse panel which should arrive today.

Under the rear seat I have a 4-way shrouded connector. One is for the red branch wire off the main harness, but the other set is a blue wire with red striping. I don't have one of these on the harness anywhere! I can't find it on my diagram either! What is it???

My harness wiring for the voltage regulator puts it in the upper left side under the hood near the autostick control valve. The regulator is not there. Nor is it under the back seat. Where the hell is it? I looked at what I pulled out of the car and I don't see that combination of wires anywhere.

Relay for the rear window defrost . . . it gets a red wire from the regulator.

ding ding. You have an alternator that is internally regulated.

The bracket for the regulator is in that corner but I can tell by it's condition that nothing has been mounted to it. This site has saved me so much trouble. I truly thank all of you.

Ill take a stab at it..
If I'm understanding you properly,you currently have an existing small wired cube under your seat,and no wires on your new harness for it?
I'm going to say that's probably a "hot start relay" that someone installed in the past..not on the diagram because not a VW part..

" Wires for a regulator that's not there"...
Do you have an alternator instead of a generator? If this is the case,then it's likely internally regulated,eliminating the big silver box stock regulator..

Maybe post some pics of both..
EDIT..man I'm a slow typer,two very smart people responded in the time I took to think and write this response..

It could very well be for the defrost..but maybe the hot start as well

The label on it is as follows:

BOSCH
IND. BRASILEIRA
9 120 080 122
K1 14V 23/51A

If in fact I do not need those regulator wires, what is the opinion on how to address them? wrap them up individually then wrap them to the main harness?

[hazmatty3614]

A google search seems to have revealed it is an alternator.

Please forgive me. This is my first automotive hobby endeavor.

What should I do with the spare wires?

Thanks again.

You may want to google alternator conversion wiring while your at it..
I'm assuming you have 2 wires from your harness now..a 30 red and the blue/ tracer coming from up front..
The red wires need to be connected three ways from the starter,headlight switch and battery and sent to the post on your alternator..
The blue/tracer is for the generator warning lamp and has to be connected to the back post on the alternator..it's likely not long enough,so it will have to be extended..use a green wire..the ground on the alternator needs to be connected as well..

There's a few different diagrams for this..I did mine a certain way as to relocate the battery under the seat..

All of my wires to the rear of the car seem to have homes except these which are circled.

They are a red and blue pair, and a set of red, green, brown.

I need to know what to do with these 5 wires.

The green, red, and brown which are marked "generator" are connected to the alternator.

[hazmatty3614]

Tell me if this is correct:

RED B+ to Battery+
BLUE #61 extended and combined with GREEN DF on alternator male spade
BRN D- to ground

RED D+ (circled) not used
GREEN DF (circled) not used
These two are on the alternator from the "GEN" harness already.

[hazmatty3614]

What I'm getting from other sources is this:

BLUE #61 connects to GREEN DF

RED B+ connects to RED D+

Brown to ground.

Seems reasonable...

[c21darrel]

Your alternator is an INTERNALLY regulated alternator (AL82). The D+ terminal needs to be wired to a 12v+ source for two reasons:
1) Prior to starting the 12v+ input into the D+ terminal will build a magnetic field which will start the alternator charging. Without this input to initially build the magnetic field, the alternator will spin but not build current. Once charging, the alternator will "self excite" itself and keep itself charging.

2) While charging, the voltage coming in on this circuit is used by the voltage regulator as a reference to control the charge rate of the alternator.

You could use a 12v/2W lamp in the D+ circuit in place of the Gen light in the speedo. This circuit, with bulb, is needed to get the alternator properly charging. Do NOT use an LED since it will have much lower resistance.

And...Alt wiring diagram.

I hate wiring!!

Thank you!!!

[hazmatty3614]

I’m going to connect the blue and green to each other, and the two reds together and to battery (3 way)

Moderator added wiring diagrams pulled from JBugs to help others in the future.......

I think that is correct. Towards the tail end of this conversion video, it shows how to connect the wires to bypass the regulator.

[hazmatty3614]

These last two replies have been a life saver. I started with a homemade harness, hacked up beyond recognition. The new wiring works harness assumes a gen and a VR. I’m understanding much better now.

[xzener]

Good luck... Buying the parts to do this myself. Let us know how it turns out.

I have all of the wiring in the car now. Most connections are made. I’m curious if anyone has created a diagram of how the switches and relays are connected to each other. I realize a full diagram will guide me, but this would be greatly simplified by having just a diagram of the interconnections of switches and relays. Bouncing around from switch wiring diagrams seems counterproductive.

[hazmatty3614]

Also, how is everyone organizing/mounting their relays? I have 3 relays that don’t seem to have any mounting hardware or location to be mounted. I’m considering cable tying them all together and then to the chassis support post in front of the fuse panel.
