So; heres the story...
My '71 FI Variant has been having Generator issues for the last two years. I have gone through three units in 22 months. I've alternately installed them myself and had a mechanic install the latest so as to eliminate whatever user error I may have introduced into the sceario. The latest we had to have rebuilt by the mechanic, as BOSCH has stopped manufacturing them. HOWEVER! We've replaced the regulators, battery, wiring, battery cables and grounding strap and have not found the source of the problem. In an effort to save myself the problem and associated costs, I have decided to remove my stereo (an aftermarket jobbie put in by the PO) in case it was the cause of the problem.

MY QUESTION: Am I insane to suppose that the stereo installation by an 18 year old frat kid could be the source of all of my troubles with this generator? As yet (following my removal of the stereo) I have not had any issues surrounding the generator, of course this has been only in the last two months...

SO! HELP! Should I pay a professional to install the stereo, is there some crossed wiring in the stereo (or somewhere beneath the dash to which the stereo may have been tied) which I should look for in hopes of fixing the issue???

All input would be appreciated.

What exactly goes wrong with the generator?
If I had to hazard a guess, I'd say it had more to do with the cooling hole in the generator body not being aligned over the hole in the fan housing. T3 generators need that cooling, or they fry in record time.

It ceases to charge the battery and stops working alltogether. Then it overheats and blows the regulator.
I have a VW specialist for my mechanic; and, while I would likely have missed the proper allignment in my installation, I should shuder to think that he would screw it up...

Thanks for the heads up on that, tho; I'll take a look at it in the morning.

Tranny ground strap in good shape?

Might be seeking ground through other means if this is bad.

How big is the stereo?? How many watts? If it has a big amp, it could be the culprit. The T-3 charging system is only rated for about 30 amps for the total system.
Head lights pull about 15 amps total. Wipers pull about 5-10 amp. Misc. lights at night probably pull about 5 amp. So with a stereo that pulls about 10-15 amp, you are over taxing the system.

TRAM!!
MY GOD! I spoke too soon! My mechanic WAS TO BLAME! The most recent generator he installed BLEW ITSELF UP, as it was installed SIDEWAYS!
Woo Hoo for VW "specialists."

Luckily, I went ahead and had Martin (GOD BLESS the DDB) install one of his Genny kits! And WOO HOO!

I love this thing.




Now there's an interesting series of unrelated issues.

While Martin had the car, he found that the fuel pressure drops from 32psi down to 18 a few moments after the pump disengages.
(we [rather, he] was checking the EFI system for faults using a diagnosis computer [such a fancy, cool toy!], because he's a kick ass guy. No problems with the EFI, as might be expected.)
Anyone know what might be causing this? It's a new (used, but functional) pump.

The search began when Audrey (the Square) started stuttering... like she's not getting fuel.

DEFINITION:
Stuttering — adjective
Lawn-mower-like putt-putting. Seems to occur when accelerating. Might be "misfiring," but I am am unable to determine exactly what that means (I know it has to do with distributor advance timing, I just have no idea what the symptom sounds like).

Martin put in a new fuel pressure regulator—a good step, which remedied the issue. Strangely, the issue was remedied (seemingly) because the new FP Regulator is set to 40psi.

I've been getting not great gas mileage (no way of really knowing this as I have no functional odometer; it's more of a feeling) but the stuttering has been non-existant.

Then, last thursday, it began again...

It stuttered even this morning on the way to school. Today, rather this afternoon, I bought fancy, expensive ($3/galon, SWEET jesus!) petrol [Chevron Super {with something called Techron, a marketing ploy??}]... strangely, this seems to have remedied the problem. It was about a 15 mile round trip driving to work and back, top speed of about 45, and no stuttering...

WHAT IS GOING ON??

Other bizarro symptoms which began at the same time as the stuttering; inconstant engine speed at idle (Martin set it to 1003rpm for me with another nifty tool, it was golden for a time), inability to go uphill (not so much an inability as an unwillingness, anyone know Sylvan hill? It'll go up, but only at about 35mph, used to do 60 easy), I think I need transmission work (I don't think slipping in first is at all related to the issues above).

Where I am at:
Something's wrong with the new Distributor and plugs/wires and it IS a timing issue?
Fuel pressure Regulator at 40psi is flooding the combustion chamber, but only is a problem with mid-grade petrol?
God wants me to drive more carefully?
Air intake issue and the thing is drowning intermitantly?
EFI problem related to Alternator upgrade (seems unlikely this would happen so randomly)?
Audrey is a finiky bitch and secretly resents me for not having repaired her front end as yet?

Thanks y'all!

I'd start with a new fuel filter. Also, your PSI should be closer to 32- 35 PSI.

Now, you've discovered the difference between a "Volkswagen Specialist" and a Type 3 Specialist. Wink

Yeah, it's nice talking to Martin and having him know what's going on.
It's also nice that y'all can explain everything in normal terms.

Getting myself a PSI gague—

What provider would you suggest for the filter? Is the one from CIP worth ordering? Waiting for. Perhaps as a backup? Is anything worth waiting for?


What does anyone suggest? FI FIlter experiences you care to share?

THANKS Tram for your help with the fuel filter issue.


So; it would seem that I am missing one of the Spark-Plug boots.

How important is this little thing; and is it important if the only replacement part I can find is shaped diferently? http://www.autohausaz.com/search/product.aspx?sid=...0Connector

The car seems to have driven as it ought to've before I noticed the missing boot....that is, untill it stopped running altogether.
So what's shakin'?

I just bought full set of correct Bosch plug wires/coil wire from Knecht's for $23. Rotor & cap by Standard (German) for $21. Might as well replace them if they're old/funky.

Talk to Toby, he made his own. In fact he sent it to me when I was working out an EFI issue of my own. It was very accurate.
As for the fuel filter, I just get them from FLAPS and I keep a spare in the frunk of my car.
Cheers

Since it is on the suction side of the pump, and is low pressure, you can use about any filter with the 5/16"/8mm hose fittings. The one on my 71 actually says "Cushman" on it. But then, we make fuel filters where I work.

Here's what I went with for anyone who does a search on this topic...

http://www2.cip1.com/ProductDetails.asp?ProductCode=VWC%2D311%2D133%2D511%2DC

I should have it by Wed. (along with a new turn signal lense for the mooshed front end, and a few sets of plugs).

Now to Manufacture (produce, procure, pilfer) a pressure gague.
Thanks for the build-it-yerself suggestion Annie!

Ill continue to update the saga I guess ... perhaps I'll begin when I take photos of the filter install.

So, my 71 would seem to have a pre-1970 motor in it (evidence from Temp Sens. II).

[Update: I am on crack—it's the one that came with the car]

Rather makes me wonder whether someone put a different one in, it came with it (crazy Germans), or ... who can say?


Here's an update on the condition of the exciting drama!

I can't make my jack work to lift the GD Effing front end, so I can't get the tire off, so I can't get to the fuel filter which is sittting on the beam right there behind the tire in the #1 most dificult spot to reach whilst the car remains on the ground.

Rolling Eyes

So, I'll procrastinate some more and confront the issue on Sunday.


EDIT: Temp Sensor II is not what I thought it was... that would be the AAR... HELLO Moron-Self!

If your talking about an OG Bilstein jack I don't know if they are safe anyway? I cleaned mine up and bought a $5 jack handle, but only used it once! Pray

Never crawl under a VW when it is on a Stock jack. In fact, now days, stock jacks are just for show and tell. I wouldnt even change a tire with one.
Buy a small hydraulic trolly type jack, AND a set of car stands. I bought my last one to carry in the car for $20 at CarQuest. Jack the car up with that, and then put the stands under it before you crawl under it.
The Rant brought to you by a person that has had a VW fall on him and pin him.

Mr. Wolfe, glad you made it, now you know one reason you did, to tell others (yes this is a thank you). That has been the only jack my Father owns and uses. Thank goodness he never needed to jack up the auto to do oil changes. Going to change that. Wink

Thanks for the info on the jack. I had thought I might like to have the trolley type pump kack (used to drag my sister about on my father's version of the same as a kid) but had a bit of trepidation about the cost. $20 I can do.

My major question has become—wherefrom doth one one jack the front end? The edge of the pan behind the front wheeel well? The owners manual implies there ought to be a slot there for the scary jack to mount to (as there is in the rear) but I am wont for such a slot.


Got the filter on (used the husband's scissor jack to go up just enough to get the tire off)... now I need to inspect the Fuel Pump Relay.

(That would be the mad-cap clicking which occurred from behind the dash when the car crapped out on me—lurch, lurch, lurch said the little car, then—click, click, cl-cl-click went the dash—then kasploosh the motor stopped running).

In looking at the Bentley about the filter and pump I found that the relay should click (it used to) when the ignition switch is turned on, but it no longer does. Neither does the pump whirr as it used to (whirr and rattle because the mounting bracket is loose).

So now I will acquire an Ohmm, Volt, and Tach-Dwell meter for with which to measure the conductivity to the little parts (tho I truly doubt I will be doing any mucking about in the ECU with testing and detatching ground wires—any info on that, placating words Tram?).

Where does a brother get a new Fuel-Pump Relay?[/i]

Usually the stock jack is designed to raise the entire side of the vehicle, front and back. I suspect that is why you find no slot for the front.
They were designed to allow a tire change......not work under the car. As far as raising the front end, I am not sure about different year designs. My' 68 allows me to place a hydraulic jack under the center of the front axle housing, BLOCKING THE REAR WHEELS, and raising up enough to place jack stands on either end of the axle. You'll see the spots.........I just don't know all the technical names. Always look for heavy metal. Cool

Edit: Yeah I know. It's not really an axle housing, but that was the only way I could describe it without looking it up Smile Smile Front Beam?
