AccuSpark Timing lamps.
normally be carried out at approx. 800 revs
with the vacuum disconnected.
All AccuSpark timing lamps come with simple connections
Connect Red clamp to a positive power source, battery or Fuse box etc.
Connect Black clamp to negative terminal on battery or earth
Connect the inductive pick up on to Number 1 spark plug lead, with the arrow
pointing the spark plug.

Ignition timing guide
general rule, the more advance on an engine without causing detonation (engine
knock) the more power it will produce.
Average timing settings are around 6 – 14 degrees BTDC at 800 revs .
The Distributor should be advanced until the best fastest idle can be achieved
within this range.
Then the total advance should be checked at around 4000-5000 revs this should
be typically be around 30-40 BTDC.
If when test driven there are any rattling sounds (pinking or detonation) from
the engine the ignition should be retarded until this stops.
If engine runs on ignition timing should also be retarded.
2. Fitting AccuSpark module
to existing Distributor
See special notes at end
of paragraph relating to specific kits before proceeding.
If access is poor and removal is necessary first remove distributor as in next
section (fitting new Distributor)
2. Disconnect low tension lead from side
of distributor (this will be connected to the module later)
3. Remove distributor cap
4. Remove Rotor
5. Remove Points and condenser, these will no longer be needed, keep screws
6. Establish correct position of module, on
many kits this is not the same as the points and often the condenser fixing
point is used.
7. Open the sachet of white silicone heat sink and spread ½ the contents on the
base of the module, keep the reminder if required at a later date. This helps dissipate the heat from the module.
Paste will not be required for those kits supplied ready fitted to a baseplate.
8. Fix Module to baseplate and fix using the screws removed from the points
9. Use the supplied cable tie to secure the wires away from the centre of the
10. Push the supplied trigger ring down onto the centre cam, this should be a
snug fit, if loose some kits are supplied with a packing piece. Place this on
first then push the trigger on. If nothing supplied wrap a small piece of tape
around centre cam and the push trigger wheel on. If it appears to be too tight, the inside surface
can be scraped with a Stanley or craft knife. The Rotor can be used to help
push the trigger down squarely. When fitted the gap between the trigger and
Module is not critical but the two should not touch
12. Refit rotor
13. Refit cap
14 Proceed to connecting your AccuSpark Section 4
1. Lucas 23: On the Lucas 23D kit it will be necessary to remove two
small lugs from the base plate in order
to allow the baseplate to fit flush
2. Lucas 45D: some kits are supplied with a trigger and a combined trigger
and rotor, if provided use the one with the best fit. Do not use both
3. Lucas 48D4 and 59D4: The small locating post for the blue
self-cleaning points should be removed, or the baseplate replaced if one has
4. Motorcraft/Fomoco: Some distributors may require the cutting of a
small slot in the base plate to allow the wires to exit
5. Fiat , Lucas DK and 18d2
kits come fitted to a complete Distributor baseplate and do not require
3. Fitting a new AccuSpark
to TDC with rotor pointing to number one HT lead. Mark the position. Loosen the
clamp and remove distributor. When fitting new distributor it may be necessary on
some models to use the existing clamp.
a. Distributors with an
offset keyway can only be inserted in 1 position. Once inserted if the position
of the rotor differs from original this should be treated as number 1 and the
cap and leads should be fitted accordingly.
b. Distributors with a gear can
be fitted in any position. It should be inserted attempting to position the
rotor to the same position as the old unit. Once fitted the rotor will be pointing to number one ,
fit cap and leads accordingly
4. Connecting AccuSpark
Existing distributor with AccuSpark
Module /Full new AccuSpark Distributor
recommended that any radio suppressors are removed before fitting.
Your Distributor will now have a Red wire and a Black or Blue wire, it may
be necessary to lengthen the red wire on some models, standard auto wire can be
used and we would recommend 1.5 mm/15 amp wire as being suitable, good quality
crimps or solder should be used
1. Connect the black wire to the existing low tension wire running to the negative
side of the coil.
2 Connect the red wire to a 12 volt
source as below
a. Standard ignitions: Connect
to positive terminal on coil. See fig 1a
b. Ballast ignitions: Connect to the 12 Volt side of the resistor or
wire (DO NOT CONNECT TO COIL). See fig 1b
if the position of the resistor or wire is unknown connect to ignition key or
the live side of the fuse box (not through a fuse). see fig 1b
NOTE : If unsure of your ignition type connect as b.
Special Note CDI Ignitions:
is compatible with CDI units such as MSD 6AL
Follow instructions and connect black wire to CDI as if connecting points low
tension wire. The red wire should be connected to the same switched power
source as CDI unit.
The Red wire should not be connected to the coil under any circumstances.
5. Starting the car
to start car, in most cases the car will start. In some cases the distributor
will have to be turned a few degrees in each direction until car starts and
best idle can be achieved. Then the engine can be timed with a strobe.
PLEASE NOTE: It is not possible to accurately set timing statically, a strobe
lamp must be used.
6. Trouble shooting and test
Note: If at
any point the module has been incorrectly fitted and the polarity reversed the
module will no longer function.
Ensure the rotor has been refitted and the centre brush in the cap is OK
Ensure that the baseplate earth wire is in good condition.
1. Crank engine to start car. If the car makes attempt to start i.e. misfires
or appears to jam, then the ignition timing will need adjustment. Rotate the
Distributor until car starts.
If the car makes no attempt to start proceed to step 2
2. Remove the centre lead from distributor cap, have someone
crank the engine while holding the end of lead near engine block ( use
insulated pliers to avoid shock ) if
lead sparks then re-check installation of distributor/kit fitment of cap ,
rotor , firing order. If lead fails to spark go to step 3
3. ( mainly Lucas 45D type ) Remove the cap and rotor , In
some cases it is possible for the trigger and module to be misaligned, it is
possible that the trigger may be too low, raise the height of the trigger by
2mm DO-NOT refit rotor or cap , repeat test 2 . If lead sparks then it will
be necessary to fit an o ring under trigger or supply a different rotor.
(contact AccuSpark for assistance ) .
If no spark go to step 4
4. Replace cap and Rotor , refit plug lead , connect the red
wire of module to the positive terminal of battery , also connect the + side of
coil direct to battery , If car starts or makes attempt to start , check all
installation . If car fails to show any sign of starting, contact your retailer

was running and now won’t start or runs poorly
the Vehicle develops a misfire when hot this could be the early signs of a
this is normally caused by the following.
1. Car is overcharging (more
than 14.5 Volts) causing the module to fail. Excessive voltage will cause extra
Voltage to run through the module, this will create extra heat and early
2. Heat sink paste has not
been applied, meaning the module is unable to efficiently dissipate heat
3. Incorrect coil with too
low a resistance or an electronic coil has been fitted. Coils with a resistance
of less than 1.5 will allow too much
current to flow and cause excessive heat .
4. Incorrectly matched coil
and Ballast Resistor or wire will cause overheating of Module.
