Recently replaced plugs, points, cap, rotor, wires, coil. Car was running great for about 150 miles then started to sputter like it was running out gas. Luckily made it to a gas station filled up and went on my way..... for about two miles and it just died!
This is a 1970 six with 45k miles. Its getting fuel, Points are good and correctly adjusted, CD box whistles when the key is on but there is no spark at the coil. Checked all the grounds and had my head in the engine compartment for hours looking for loose or broken wires. Any ideas????? And by the way, if you have classic car insurance make sure you opt in for the towing. I didn't, $175.00 for the hook up and a 6 mile trip!!! |

Tony and John are dead on with replies,the bosch 3 pin can buzz but still have issues , these units are so old now and prone to failing,when researching my system I went for the "blue" (75 911 MY ) Permatune which is known to be very reliable,however they require a matching permatune transformer coil which is rather spendy ,I was lucky to find a NOS unit for sensible money on Ebay.
Ashlocktech offer a rebuild service for the Bosch CDI's which compared to risking buying secondhand is a good option @ $279 with your core , good price really. Pretty sure you need to match the coil to the CDI you have also. Good luck. |
