New kind on the block and no doubt going to be a regular now that I have a 1990 TP in the family.
TP / Carby / 5sp Man / GLX

bought from a neighbour as he is now 86 and can't drive. Son has been driving it for the past week and no problems until now. Picked up his sister and the car just died on him. Turns over great but that's it.

New dizzy, rotor arm and coil. Problem now is that there is no spark. Checked all that I know or remember from 20 years ago. The only thing that I'm thinking now is that the module inside the dizzy is blown. Not quite up on how I would test it.

Help.

make sure the cap is sound

that the rotor is making contact with the carbon pick up inside the cap --they break

you say new dissy .. if new-- it will have a new module in it and they rarely give trouble

you didnt say you have new leads or plugs

tests
to test coil #
-take the coil lead out of centre of the dissy
and rest it near the engine rocker cover -- crank over-- see if it sparks

#
spark plug /lead test /module /cap

use a lead you know is good - see if it sparks

if you need the module test(pick up coil ) + its a multimeter or test lamp to test continuity -

My bad with Dizzy as I meant dizzy cap(brand new) not complete dizzy. Rotor arm touches carbon tip fine, did the old lipstick test to check contact.
Did the lead off the centre of dizzy to engine = No Spark.
Measured 12.0v is getting from battery, through ignition to ignition coil.
Measured 5th lead for continuity and all seems good including the bend test.

This is why I'm now stuck.

Ignition coil or (more likely) power transistor.

1990 TP carby
this car was running then stopped >no spark
you have confirmed there is volts to the coil side .cant be an ignition switch problem'

and the coil is new ..

I assume its the round type coil fitted
one with condenser ... or one without

the module is carby specific

bosch is genuine about $70 =ebay

after market $40 carby dissy module = ebay

I had trouble with the control module; was intermittent. Car going along and then just dies for maybe a couple of seconds and then picks up again.
Replacing the module fixed it.
The module is driven from a coil and a rotating magnet; the module conducts for a certain time period independent of the motor revs. This fixed pulse width is also used to drive the tacho circuit. The module is common to other aussie cars.
It is important to uses the heat transfer paste supplied withe new module.
Hope this helps.

Might not apply to the carby version but on the EFI version I has a similar problem
Was a case of - clean up the dizzy connector (tend to corrode when condense enters the plug - cracked rubber!).
Jiggle it and see if the engine sparks up.
