Optical Switch and wish to replace it. As the system was fitted
a number of years ago will a new optical switch be compatible?
The Optronic Optical switch and power module was re-designed in
1983 and if your system was manufactured after that date a new optical
switch will be compatible with your power module. Please check Technical
Bulletin 16 in the Optronic technical section of this site for further
information on component compatibility before replacing this unit.(link)
13. Will my coil be suitable with the Lumenition
Optronic system?. If not what would you recommend?
The Standard Optronic System is compatible with the original coil/
coil & Ballast resistor used on contact breaker vehicles. If
in doubt you should check your coil using Lumenition Technical Bulletin no.
7. Or your Lumenition supplier can provide a compatible coil and
ballast resistor from the Lumenition range.
14. I have an Optronic ignition system
and I want to replace the coil on my vehicle. Which one do you recommend?
The Lumenition MS4 coil is recommended for this product. This is
a coil and ballast resistor combination (which gives the best charging
characteristics) ideally suited to Optronic Ignitions. Product information
can be found in the installation instructions section of this site.
15. Can I purchase directly from you? If
not, where can I find a dealer and a retail price?
We sell through our comprehensive dealer network. These include
catalogue and Internet dealers. Click here to find a Dealer
and Click here for the retail price.
16. Will my tachometer (RPM meter) work with a Lumenition

fitted. There is a known issue with Smith current sensing tachometer
(RVI) which is fully described in Lumenition Technical Bulletin no.15.
17. My vehicle runs on LPG. Is the Lumenition Optronic
18. Is the Optronic system suitable for
Yes. Lumenition manufactures a special marinised version of the

First contact the dealer from which you purchased your system.
Any returns must be via the dealer, unless any special arrangements
have been made with Autocar direct.
23. I don’t have a spark or have intermitted
misfires. What should I check?
Please see Troubleshooting document here. Lumenition Technical Bulletin no.17
24. I have fitted the Optronic system to
my vehicle and it is working perfectly. However I have noticed that
my coil is very hot. Is this normal?
This is not necessarily an issue. All Coils get hot in operation
and it is possible that you have not noticed before how hot the
coil became before fitting an Optronic ignition. It is also likely
that any additional coil temperature is only occurring on tick-over
and when the engine is driven the coil temperature will return to
similar levels or below those generated using points. This is not
a fault and is created by the way the Optronic system operates.
The rise in temperature is unlikely to damage the ignition coil.
Please see our product technical section for further information.
25. What is the difference between the
Performance Optronic system and the standard system?
The Performance Optronic coil comes with a special power module
and matched constant energy coil for improved power range and performance.
26. I wish to rev limit my engine to prevent
accidental damage. Which rev limiter from your range do you recommend?
Lumenition and Micro Dynamics carry a range of rev limiters from
pre-set engine bay models to driver-adjustable full-throttle gear
change versions. The Lumenition ERL-V and MicroDynamics RL-range
are the most practical for single-coil applications where a pre-set
limit is required. For racing or fast road applications the Micro
Dynamics digital ranges are the most applicable. Download the product
catalogue from this site for general rev limiter information and
visit the product section for more detailed guides on facilities

management systems give me over Carburettors?
Lumenition electronic engine management systems offer total control
over the timing of ignition events and the fuel supplied to engines
over the complete rev range. With visible and instant adjustment
and feedback via the CAL600 computer software it is possible to
tune an engine to the best power profile for your vehicle. Even

fitting. These can be fitted on any engine for which a suitable
Weber-style manifold can be sourced. With idle speed control and
an advanced cable linkage and fuel rail system these throttle bodies
have proved ideal for race and road tuned vehicles alike. Lumenition
