The Ghia died :(

« on: March 28, 2005, 11:38:03 AM »
After being very proud of myself sorting out the distributor, the Ghia has now thrown another problem at me!

Over the last week or so the engine has been dying on me, usually when trying to start up.  It'll turn and start fine but will stop running for a second or two, usually coming back to life again before completely stalling.  After it's warmed up (if I manage to keep it running that long!) it'll perform OK, but occasionally do its dying trick whilst running.  On Sunday it partially died when I was on 153 - the engine was running and pushing the accelerator did turn the engine more but without enough power to pick up speed.  10 seconds later and it came back to life again.

This morning it did it's trick a few times but then refused to start at all :(

I checked a few things quickly and here's what I've got so far:

- Electronic cut-out valve on the carb is working (if I plug/unplug the wire whilst the ignition on there's a definite and loud click)
- I put a timing light over spark plug wire #1 and there was NO strobe when I turned the engine on the starter.
- Ignition power appears to be getting to the coil OK
- Points are correctly making/breaking (tested resistance)

It looks like there's a problem with the high tension pwoer getting from the coil to the distributor - so my guess from all this is that either the coil or the condenser has failed.

Any further tests I can carry out to locate the problem?

Thanks all!

Im not sure how you are checking things out. Do you have a test light or a volt meter to see if you indeed have power( 12volts) to the the coil ?
 Its kind of strange to have this problem to just come and go and be electrical, but I have seen coils drop voltage when they got hot. Kind of rare if its a Bosch coil. It sounds more like you may have a fuel related problem. Not being there, its kind of difficult to know what is going on.
 I presume you have the dist. tied down now and the point gap and Ing. timing set properly ? :?:  :?:

I was in a rush this morning so admittedly didn't fully test everything.  I've got a voltmeter so can test the voltage to the coil easily enough (I assume just between the two connectors on the base of it?)

The distributor is properly clamped.  Point gap is pretty much OK (set with a feeler gauge - I have a dwell meter but haven't used it yet).  It's definitely making & breaking contact (resitance tested between green wire coming into dist and internal base of dist).

Timing is not bad but again needs perfecting.

The fact that the engine was running pretty much smooothly indicates to me that the point gap/timing is probably OK (well, OK enough to let the engine run anyway or at least make an attempt at starting up).

It could be a fuel problem (knowing nothing about the history of the engine leaves me to suspect everything!) especially as the fuel line has been re-run at some point and that was my first guess anyway.  However, lack of timing strobe light when I try & start the engine points me to electrical problem.

Incorrect on the voltmeter. Put your voltmeter on 25 volts, positive lead on the + side of the coil (black wire from the harness) , Minus lead from meter to ground (earth to you) . Turn Ing. on . You should read at least 12 volts.  Forget about a dwell meter on a VW unless you just like to take the dist. cap off 100 times trying to get the points right. Set the points on .016 and forget it.  Timing cannot be somewhere close. It has be correct and the advance has to be working properly. Absolutley NO guess work here. Check your rotor button . if you have a Bosch button ,it has a resistor built in  . 10,000 ohm  from the center out to the tip.
   After all this fussing around, Have  you ever giving the engine a major tune up ??  I still say you have more than 1 problem going on here.

I'll check the volts across the coil tonight.  I'm pretty sure there's power as the cutout valve operates fine and that connects to the black wire on the coil.  

I'll try testing for fuel delivery as well - I assume that removing the pipe from the pump to the carb & turning the engine should produce fuel!

The car won't start so it's not easy to set the timing but I'll have a try tonight with the help of a few manuals :)

The engine hasn't had a major tune up since I got hold of it (end of Dec) which never helps.  There's undoubtedly more than one problem with the engine, I'm just trying to fix each bit at a time!

You are probley ok with the voltage. You could pull the center coil wire out of the cap and hold about 1/8 inch from a good ground. Get someone to spin the engine over and see if you have a good spark to ground. If you have no spark, like you said, you could have a bad coil, or something in the dist. messing with you. Its hard to piece up a tune-up.

The good news is I found the problem and you were right - something in the dist has definitely been messing with me!

The wire that goes into the distributor and connects to the points was shorting against the dizzy case.  I moved the wire by hand, fired up the engine and it ran perfectly :)

As you can see from the picture below it's been "fixed" in the past with some very bad gluing.  Is it worth trying to fix it up again myself or is it easy enough jsut to get a new distributor?

From the looks of the picture, the "fixed up" area is part of the condenser that hooks up to the wire from the points.  The condenser has a plastic insert on the end of the wire that slides into the open spot (squarish in shape).  The plastic insert holds the lead that connects to the wire from the points.  If you get that goop off of there, and get a new condenser (might as well do points, cap, rotor button while you're at it), the plastic piece "should" push or slide right on in there.

I'm saying this just from looking at the picture.

Now, if under that goop, the distributor is cracked, broken, or otherwise "messed up", then you can get a new distributor ...or a used one at a swap meet.

OK, looks like I'm doing a distributor overhaul this weekend then :)

I did get a replacement set of points from AutoZone but the wire connected to the points was coming out the wrong way (if that makes sense!) so will need to relpace it.  I'll try & get a rotor & maybe cap as well, probably also HT leads (the spark plug end rubber boots are burnt & hard!).  I changed 3 plugs the other week but couldn't get the fourth out :(

Makes sense to me.  First mistake is Auto-Zone. All together now! Can  we say Bosch.  Bosch wires, Bosch points, Bosch cond. Bosch rotor, Bosch plugs (W-8). Im not trying to be a wise-ass , But Bosch works and the engine came with Bosch when new. I just took out a set of brand new Auto-Zone points that were grounded . No fire.  I can get the plug out for you ,but if does strip the threads, I can tap and install a KD bushing without removing the engine or clylinder head.

Hey ,I just saw Travis`s  post and the pic. He is correct about the "goop' being the mounting hole for the condenser. One more thing,if the hole is square , you have to have a strange little forked clamp to hold the cond. to the case. Bosch Please!

OK I'll aim for Bosch then!

Where can I get the Bosch parts in Chatt? I'm located downtown but can get to the malls easily enough.

I'm guessing that I won't have that forked clamp - possibly why all the gloop has been put there.  Is this an easy bit to find?

Jim Lockhart should have them. You will need to get the little screw that holds the condenser clamp also
