 |

| I just installed a new kuhlworks 034 dist in my bug. Electronic ignition! Bug doesn't seem to be getting fire now. 2 wires red and black from dist red to pos on coil black to neg on coil black wire connected to wires going to choke and idle shutoff connected to gether to pos on coil and one wire like white or gray with red stripe just hanging there like it was before. Where have I gone wrong put it back in same position old rotor was when I took it out Old distributor bottom where it goes on dist drive was loose so I don't believe I did wrong by changing dist just something not working right. Help please!!!![img][/img] |

What about the wire from the front of the car that supplies power to the coil?

Are you not getting spark, or getting spark but engine not firing?
#1 spark plug wire may go in a different position on the distributor cap. |

You will have to get your test light out and see where number one actually fires. It will be off a little or a lot from where your points fired.

Confirm you have 12 volts at the coil. Then, put your engine on TDC compression stroke on #1. Where the rotor points to on the distributor is where that #1 spark plug wire goes on the cap. Then, install the rest of the spark plug wires in the correct order on the distributor cap.
Make sure you don't hook the wires to the electronic ignitor wrong. It will fry them instantly.

You aren't specific about what your old distributor was. If it was an uh oh 9 then your firing positions will be different with the new distributor. This might also be true for the Kuhltek. The kuhltek's do not have the best reputation on here.

Are you sure the electronic module is not fried?

re-install the old distributor and see what happens?

| What is to be gained by using a new distributor? A properly maintained original German OE component is far superior to anything aftermarket. Consider restoring the original |

That's good information, the number one should be in about the same position, use your test light, as in static timing, to zero in on 0° TDC timing to start the car and use the timing light to dial it in.

Only comment is that unless the old dist was bad, you should have just got a compufire or Pertronix module for it. I bought a Kuhlwerks a few years ago and allthough it worked, was not happy with how it worked. Its in my "spare" box now.

| Installed old distributor now bug won't idle shakes pops and generally sounds like crap and has no power. Distributor only would go in one way so I figured that that had be tdc cyl 1. I need help |

What did you mean by the above??
Black wires on VWs are ignition switched 12v+. The stock black wires running to the ignition coil connect to the #15 (+) terminal.
The electronic points module (which is not a VW or German product so does not follow the same wiring colors) uses a red wire for 12v+. So the red wire from the electronic points should connect to the same terminal as the other black wires (+). The black wire from the electronic points is not ground, it is the trigger to fire the ignition coil. This black wire from the electronic points is connected to the ignition coil #1 (-) terminal and should be the only thing connected there (unless you have a tachometer which also connects to the #1 terminal). No other wires should connect to the negative side of the coil.
If you accidentally wired these two wires from the distributor backwards on the ignition coil and turned the ignition ON... you likely fried your electronic points. The instructions should have been very clear on how to wire it. Some newer electronic points are better at protecting themselves from burning up when wired wrong. Many of the less expensive one are "toast" when wired wrong.

Your spark plug wires are not installed correctly around the distributor cap.
You are correct that the distributor can only be inserted one way, but unless you had the rotor pointing to the #1 plug wire before you removed the old distributor and you did not turn the crank at all... you cannot assume the rotor is still pointing to #1 plug wire.
The proper way to confirm the #1 spark plug wire position around the distributor is as follows:
Ignore any marks on the distributor or any diagrams which show where on the distributor the #1 plug wire should be. Different distributor models have #1 is different positions... there is no one correct location. Also, if the distributor drive shaft is installed incorrectly, the rotor could be pointing to any one of 12 different positions (12 teeth on drive gear).
Rotate the crank pulley until the timing marks (or TDC mark) lines up with the case split. You are now EITHER at #1 or #3 TDC. You cannot yet know which.
Remove the #1 & #2 valve cover (right side of engine).
While you watch the #1 cylinder intake and exhaust rocker arms (#1 cylinder is closest to the right front tire) rock the crank pulley back and forth an inch or two. If #1 rocker arms remain motionless, you are at #1 TDC (the valves are not moving when the cylinder is at TDC at the end of the compression stroke). If either/both #1 rocker arms move, you are at #3 TDC (#1 is at the end of the exhaust stroke). Rotate the crank pulley 360deg and check again.
Once you confirm the #1 rocker arms are not moving and the timing marks line up with the case split, you know that the crank+cam are at the end of the #1 compression stroke (#1 TDC).
Now look at the distributor rotor. It WILL be pointing to the #1 spark plug wire position on the distributor cap... it MUST be. The engine is ready to receive a spark at #1 spark plug, you now need to make sure it is delivered there.
If the #1 mark on the rim of the distributor is NOT lined up with the tip of the rotor, rotate the distributor body until it is (do not rotate the crank). This mark now shows you where the #1 plug wire should go. Do not trust this mark until you have confirmed it is correct (you make it correct). Note: If your distributor drive gear down in the case is installed incorrectly it may not be possible to orient the distributor with the #1 notch at the rotor tip... the vacuum canister could interfere with the fuel pump or intake. The engine will still run if the mark is not lined up correctly, you just need to be aware of where #1 plug wire belongs.
Once you have identified the #1 plug wire position around the distributor, install the distributor cap and put the #1 spark plug wire into the post above the rotor tip. Install the remaining wires onto the cap posts in the clockwise order or 1-4-3-2.
Lastly, if you rotated the distributor body, you can static time the distributor just to get it started and then you should use a strobe timing light to set timing correctly based on the model of your distributor (not your engine or car year).
Once you have your engine running well, use a black marker to # the posts on your distributor cap. The cap can only be installed one way on the distributor.

| Got old distributor back in points type ignition. Bug started but missed wouldn't idle no power etc. now won't start. Checked point gap set at .016 number one tdc static toned with test light. Then it would stat but not run right. Rechecked point gap still at .016. Could this be a condenser have gone bad just sitting on a shelf. Won't start getting fuel have compression but no start. Prior to all this started and ran pretty good I was trying to help it by changing to electronic ignition. Bad mistake apparently! Help anyone!!!! By the way there is a white with green stripe or could be yellow with green not connected to anything coming out of harness in engine compartment where black for pos on coil comes out anyone have a guess what it might be |
