Bosch CDI Repair and Restoration

Hard or intermittent failures in these units typically involve a failure of the main power components (high voltage discharge capacitor, power transistor, thyristor or open board traces).  

At the time of manufacture the units discharge capacitor used a technology that is prone to failure with age and use. Simply stated, this part will fail and may cause secondary failures when it does.  Also, components often get damaged by reverse or over-voltage events caused by faulty vehicle charging systems, over-charging  or jump-starting a dead battery.

Servicing the power components in these hand-wired units requires extensive dis-assembly. Defective parts are replaced with modern high-quality devices with performance ratings superior to the original 40-year old parts and as a matter of policy, service always includes replacement of the discharge capacitor with a device that is more robust and does not rapidly deteriorate with heat and use. 

Contrary to popular opinion, it is not necessary to replace all components in these units.  With noted exceptions, the majority of components used by Bosch are not stressed, are high quality and generally do not require replacement. And, service now includes certain mods to 'harden' these units against voltage transients.  An additional-cost service is also offered to install a rev-limit feature in the unit.

If you suspect your unit is faulty, (or you're tired of crossing your fingers!) then contact  Bob@AshlockTech.com and arrange to send it in for diagnosis and repair.  It's the smart choice compared to substituting a 40 year-old used unit with questionable life expectancy.   Over 500 of my restored units are already back in reliable service!  


Here's what I offer:

CDI Repair and Restoration Service:  $199 plus shipping 

  • Repair, Restore and Test:  YOUR defective unit is repaired, stress-tested and warranted for 1-year.  The repair price includes cosmetic restoration (cleaning, bead-blasting and re-labelling) to provide a ‘like new’ appearance as shown above.  FAST turnaround too!

Ready to ship Bosch CDI Units:  $399 plus shipping

  • No core to send in for rebuild?  In a hurry?  An inventory of restored units are kept on-hand for immediate shipment. Why spend over $400 for a salvaged, un-restored, questionable box when you can have one that has been rebuilt & restored, works perfectly and carries a warranty?  Inquire for availability!

I also buy Bosch CDI cores, working or not.  Offer varies based on condition.

New Twin-Spark CDI by AshlockTech

Introducing the new AshlockTech Twin-Spark CDI unit.  A new design to address the needs of 4-cylinder Porsche type-616 and Polo Motor twin-plug applications.  And of course, suitable for use in other applications too!
Adaptation into the familiar Bosch housing presents a desirable, period-correct appearance.

Outfitted with modern electronics to give strong, synchronous sparks.

High efficiency design runs only warm to the touch.  The majority of power consumed goes direct to the spark plugs, not as internal heat typical of Bosch units.

Reverse-voltage and surge/dump protected design.

Internal components solidly mounted and resistant to vibration damage.

Familiar 6-pin connector design, or optional flying cable with 6-pin receptacle.

Consistent, regulated output across normal input voltage ranges, as well as during cold-start/low-battery situations.

Built-in soft rev-limit programmed for your application.

Simple triggering by conventional points or electronic points eliminator units.

Optimal performance with the original Bosch CDI transformer-coil, or aftermarket CDI coils with similar parameters.


Available starting January 2018

Send in a decent Bosch core unit for conversion.  Units also available outright at higher cost.

Inquire for pricing and delivery.
