Hi everybody!. Me again. Now, during some workshop tests, after the change of my distributor (from electronic to points - electronic k.o.), we check the force of the spark make with my old coil (original one - 38 years on use), and the spark was...yellow (like a coal flame)!.

I understand the spark would be blue, then, bad news for me, I need to change the coil. Of course, on my country (Peru) the probability of adquire a original coil are null. My alternative option: a "blue" bosh coil.

Then, my question: How many steps are need to fill for install the new coil? If someone has performed this exchange before on an Amazon, please write me some lines about his/her experience.

Thanks in advance...

PS.- My usual excuses due my spanglish...(or best speaked, my misuse of the Shekeaspere language).

I just changed my coil over to the blue bosch. What a friggin differance it made!! My top end rpm's just keep going and going now, and the old b20 just seems to roar to life. I have no ballast resistor hooked up...is this bad? Also, I removed my armored cable the easy way. I clamped the cable in a vise, and used a sledge hammer to POUND off the coil! Whala... it worked great...heheh

Blue coils has the resistor (ballast) integrated into the can, the red coils need external ballast. ¿Are your coil Brazil-made?, in Peru, the Mexican-made blue coil has low scores on quality (as reported by four -of eight-local car workshops). Germany no make this coils since the previously millenia :-)

When I had points on my 120 I never could get a "blue" spark, it was always more of a "yellow" spark. The car still ran well enough. Try setting up teh car with the original coil, it's rare that they fail.
p.s. I had all sorts of capacitor compatibility problems when I tried using a Bosch Blue coil with my points system, I was burning points like crazy. That's why I ended up going to electronic ign.

Thanks Patrick, I check (on a car electrical workshop) the coil last saturday, the damm thing not fit the minimal requirements (some shortcircuit inside,as the technitian speaks: "esta @*&# se ha cruzado"), and probably, the coil was the cause of my fried electronic module (a little one, into the distributor, similar to Pertronix).

I select now a red bosch coil, 28KV, for points and electronic use. Next week I will try to put the coil into the car (just now I´m seeking for a 0.8 ohms ballast here).

A coil from a 240 will work fine. You need to use the ballast (which looks
like a metal inline fuse) so that if you stop the engine with the ignition
turned on you don't burn the coil.

You will, of course, have to cut the armored cable to get to the wire
inside it.

Keep your eyes open for Paul Bosland, the chile (ají) expert from
New Mexico State University. I hear he is hunting them in Peru.

Gracias George, por aqui los 240 estan de moda entre los autos de segunda mano (su diseño tipo tanque lo hace un auto seguro en una ciudad con taxistas locos), asi que sus partes estan algo escasas. Mirare a ver si veo a Paul Boslard por aqui (¿es un amigo, compañero de trabajo o brickfan?).

The same on English:

Thanks George, here the 240 are one of more popular second hand cars (the tank design are a safety car on a country with mad taxi drivers), and due it, the spares are a little scarse. I will be look for Paul Boslard (Is he a friend, workpartner or brickfan?)

Con mucho aprecio,

Joaquin

I did exactly the same thing on my 122S. You will find a terminal on the back of the ignition switch, outside the armored cable, that is "hot" in both the RUN and START positions. That goes to the (+) side of the blue coil. The wire from the exposed terminal of the original coil goes to the (-) side of the blue coil.

On mine, I simply left the old coil in place and mounted the blue coil near it. If anything ever went wrong with the blue coil, I could always reconnect the original and keep driving.

Thanks Phil, I will made same, but with a little different coil (blues has some quality problems here).
