K2543 electronic transistor ignition kit, conections

hello I am trying to connect a K2543 kit in my car which is equipped with a traditional distributor with breaker points, it is a 1971 dated 6 cylinder engine car

my car has a coil with a ballast resistor connected to it

in the page 7 of the instructions of the kit K2543 i can read the following:

“follow the instructions…connection 1 of the PCB,…if a ballast resistor is used, the connection must be made in front of this resistor”

my question: what does “in front” mean ? does it mean that i have to connect the number 1 of the PBC to the resistor and then connect the resistor to the coil ?

regards and thanks

Basically it means that the unit must receive the +12V direct from the ignition, you cannot put a current limit resistor in series with the kit.
The resistor should go in series with the ignition coil.

hello, i appreciate your answer, please see the following scheme to check if i understand well what you said

this is the actual installation in my car:

910×615

and this is my understanding of the connection of the k2543, is it ok ? as you can see the point “1” of the kit is connected direct to the same point of the ignition, and the resistor is maintained for the coil

910×615

thank you

As far as we can tell, this could work.

hello, thanks

here it comes another question

if i want to protect the circuit should i incorporate a fuse in the connection Nº 1 (the positive)
if that is the case, which fuse will be ok: 2`5, 3 or 4 Amp ?

can i put also a green diode in the positive line to see that the kit is on ?

regards

A fuse is a good idea.
Fuse rating depends on power consumption of ignition system.
Yes, you can put an indicator from the (+) supply to GND.

HELLO
thanks for answering, but about “fuse rating”: don´t you think that fuse is going to affect ONLY the velleman kit ??, so probably it will be related to the velleman kit power consumption only ???

if that is the case, the velleman kit has a consumtion of 4Amp, so which is the correct fuse for this case ? 4 or 5 amp ?

thanks

Kit carries the complete current (kit + ignition).
