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 |

Notes from my plugs research: NGK BP6ES voted best plug for 914 (per Cap'n Krusty): http://www.914world.com/bbs2/index.php?showtopic=217463 BOSCH W7CC for carbs (then adjust heat range based on particular engine). Reputable local 914 racer says you can use the Bosch 4 prong plugs #4417 but I havent tried them yet. I am betting the NGK's I have now are what is voted best. Things runs pretty good with them for the shape the are in. Think I'll just get another set and move on from there. Thanks for the info! I want to refresh the ignition system and fuel system. Are there any places that offer upgrades? Replace the points/condenser with solid state ignition. Points/condenser are 1940's technology. Several options available; I've used Pertronix in several engines. Set 'em and forget 'em. I will have to look into this! Is this a simple bolt on type upgrade? Any reputable places to buy? Thanks a million Cheers Nemi |
