Are there more than one type of the gold Sports Coil? And which one for my +2S130/5 with lumenition?
Thor,
Others will probabably have different opinions but I and several other people I know use a Bosh Blue coil, this is after Lumenition has been fitted and the rev counter bounces around. By fitting the Blue coil the the rev counter is fine…I do not know the reason why(and dont particually want to know) but it works for me and others…

My twinc has the Lumenition magnatronic “points” with a blue Bosch coil and the tacho works just about OK. It does read a little low at hight rpm. I plan to have it converted from RVI to RVC at some point.
Lumenition also do their own coils to match up to the various types of systems they do.

AHA. WHAT KIND of Bosch blue coil, does someone have a parts number? As I do have a bouncing tach., as well as a problem which might be coil related, so why not do two flies with one stroke…Alternatively, lucas sports gold, but which number?

Excellent tip! Will search,…
I purchased a Bosch blue coil from www.burtonpower.com part no 0221119027
I recently had what I thought was aftermarket module failure on my MGB. I replaced the Crane box and Crane coil that was in it and it still didn’t work. Replaced the rotor and viola! I believe the overly powerful spark broke down the dielectric in the OEM Lucas rotor.
I now have a Pertronics “inside-the-distributor” type system with a Bosch coil which seems to work well, but it also fixed the bouncing tach syndrome I’d had for 10 years with the Crane system. Steady as a rock now.
Bosch blue coil bought now, the one in the “bad” section supposedly the best of those… part number 0 221 102 082 (0 221 119 027), metal casing with blue stickers. Hopefully this is the one to make the Lumenition and tach perform as they should, and replace the lucas sports which looks like is bust. (engine cuts out completely occasionally when warm, usually in the middle of crossings…, will start again soon after).
Is this the right coil?
InAustralia the Bosch sports coils are red. Used them for lots of years on all my Lotus with no problems with both points and lumenition and Lucas and Bosch distibutors

According to this website the Blue coil needs no balast resistor but the red coil requires a resistor.

In Australia the red came in ballast and unballasted versions or at least they did. I have a 6V ballast type on the Esprit and unballasted 12V ones on the Elan and plus 2. I have not bought one for a few years, probably actually about 10 years so maybe they have changed their conventions!!

hmm… It says on the box: “For igintion systems without ballast resistor” I take it then I’m safe to take off the Lucas Sports gold coil and just plug in this one…?
It’s a +2S130/5 with Lumeniton by the way.
Yes, assuming you do NOT have a balast resitor and you have a full 12v feed to the coil.
Brian
There should be shouldn’t there? with the lumenition fitted already.?There’s no ballast resistor on the Lucas coil (gold sports type), not that I’ve ever really understood what one is anyway, except for it is usually connected on the outside of the coil, right?
“]There should be shouldn’t there? with the lumenition fitted already”.?..
I would think so, easy way to check is with a volt meter with ign on…should be 12v + at the feed to the coil.
" it is usually connected on the outside of the coil, right…"…
Usually yes and I think Lotus only used the external type mounted on or near the coil.
Brian
I might be a bit thick, SORRY…, but the text on the Bosch coil means that there shouldn’t BE one fitted in the circuit, rigth?, not that it’s built-in to the coil. The gold Lucas one doesn’t have a built-in one does it?

Quote from the above website:
“12 V high-performance ignition coil without start-voltage enhancement.”
Which means to me it has NOT got a resistor and does NOT need one, I do not know about the Lucas coil…sorry!
