69 vw wiring

[csalwes666]

hello guys I have a 69 vw it has a generator it's had wiring done to it, my question is I have a red wire on the + of generator a black wire - of generator and a green wire that looked to be a ground on the body of the generator. when the green wire is hooked up to the body of the generator the car has the generator light on, when I disconnect it it charges also they have a amp gauge hooked up this a fuse when driving above 20 mph the fuse pops and also blows out my headlights any info would help it's driving me nuts thank you

See the wiring diagram below,

Using the above diagram as your guide... find the generator (C) and the voltage regulator (C1) near the bottom half of the diagram. Note the wires running between the two:

D+ (thick red wire) runs from the D+ threaded stud on the generator to the D+ terminal on the VR.
DF (green wire) runs from the DF threaded stud on the generator to the DF terminal on the VR.
D- (brown wire - not shown) runs from the D- screw on the body of the generator near the fan end to the base of the VR so the two share a common ground. The attachment screw on the VR may not be marker but it is clearly an odd screw on the base metal frame of the VR.

thank you I'll look there as a start, what I don't understand is when you turn the key on the green wire they had as a ground is hot.

The green wire coming from VR61 goes to speedo gen. light not ground.

thank you ashman I chased the wires they had the df as the ground on the generator body and the brown wire was on the df terminal it seems to charge at idle now but at sbout1500 rpm the generator light flickers I'm thinking maybe the voltage regulator might be fried.

Not clear from your above description... you found that the wires were running incorrectly. Did you correct the wiring? Did you test the charging system output after correcting the wiring?

Follow Speedy Jim's steps to test your charging system:

Report back your results.

I did run the wires the way there supposed to be, i was looking at the amp gauge on the dash at idle it is charging when I rev up the engine the amp meter goes to zero and the generator light flickers on and off. I will put a meter on it today.
