So I am stumped. When I took delivery of my newly acquired 74 914 the car would start up just fine with a jump box.
I went out and bought a new battery and now I have no spark... at lest from I can tell doing the simple spark tests I have done. I just did an Ohms test on my Ignition coil and here is what I got Primary: 1.4 Secondary: 10.41 Per the Pelican Technical Article I should see readings like this: primary coil winding's should give a reading of 0.3-0.6 ohms. Secondary coils should be near 600 ohms. If I understand my results I am significantly higher than where I should be? But does that mean my coil is is the cause of no spark. The only thing I changed was a busted fuel line and put in a new battery... Now the car will not start. Any ideas on where else to look? Thanks in advance Cheers Nem |

After changing the cap, rotor, wires, points, condenser, and plugs as well as fresh filters and oil she finally runs again. Not the greatest, but I was able to drive it. Seem to be switching back and forth between the original coil and new as it would heat up and not start.
The drive was okay... needs suspension work and possible a transmission rebuild! NO 1st gear at all. Goes into 1st well enough, but as soon as the clutch is released it grinds its self out of hear.... any ideas on that one? Is 1st gone? The best part about today is getting it started. May not be able to drive it for some time.. but its a start. |

NO 1st gear at all. Goes into 1st well enough, but as soon as the clutch is released it grinds its self out of hear.... any ideas on that one? Is 1st gone? It's gone. Likely due to years of chronic mis-adjusted clutch cables. It can be fixed without removing the transmission from the engine. http://www.pelicanparts.com/techarticles/9...anny_repair.htm --DD |
