Default Bosch Light Blue 12 volt three Ohm Coil

I am having a hard time finding the Bosch 12 volt three Ohm Light Blue coil PN 000. I see them advertised in many placees ! I llive in gardnerville, Nevada which is 50 miles from Reno. I found a place in reno that said they had them. I ordered them as they only had one. ( I am using a H& C Dual Coil Distributor) At the time I ordered them I gave them the Part Nomber. When I got there they were the correct part number . But they were a dark blue color I asked if they were three Ohms and they did not know. Also they were made in Mexico!!. Mfg name was Bobina alta encrgia? Mexico. Bubba recomends the Light Blue three Ohm Light Blue 12 Volt Coils for the Harmon & Collins Dual Coli Distributor PN-00012. Any help would be appreciated. Thanks Stan

I bought two of the ones that Bubba shows from Amazon - work like a charm on a H&C Dual Coil.

Given the challenges with the secondary high-voltage yellow plate on the H&C distributors, I highly recommend that you have the entire ignition setup and tested on a distributor machine by somebody who knows them.

Of the four H&C distributors I've recently worked on, only one didn't have an issue with the secondary spark finding ways to go to ground inside the distributor. This causes issues with four of the cylinders not firing correctly (or not at all). I've made appropriate mods to resolve the issues - depending on what I find. Also, make sure you run solid-core spark plug wires - you do not want "resistor" wires or spiral core, they cause the secondary problems to increase.

Lastly, it is important to synchronize the points on a distributor machine - I've seen them as much as 5 degrees out of sync if one just installs them, sets dwell and runs them. Best of luck!
