How to wire up points with vac advance.

ariarne, Nov 20, 11:20am
dizzy in place of fully electronic dizzy! have a 94 galant with 4g93 soch and keep having to replace ignition module at $300 a pop. car still has lots of life in it and dont want to scrap it just for that problem. found a points dizzy wih vac advance but unsure how to wire in to existing loom, realise a ballast resister is needed in the line but were/ which way im not to sure! any help would be much apreciated.

ummmm i can tell you why you keep having to replace the ignition module
because you neverchanged the leads for new ones nor fitted new plugs.
Thi ignition module gets nuked by backarking from old worn out ignition cables and worn plugs.

new ignition module carry a lifetime warranty but only if the leads and plugs are also new.
I had a module fail once on a honda the aprentice simply ordered the wrong module with the same plug and the car broke down again 1 week after. they found the problem and because i had purchased and fitted new leads and plugs the module was replaced free of charge.

As intrade suggested. Old leads and Plugs get higher resistance (in the leads due to age, plugs due to bigger plug gap/worn electrodes etc) and this puts extra stress on the module/coil/firing pack. More stress = more work = more heat = short life

Changing to points won't help either, it will just wear the points out faster and you will be having to adjust/replace them all the time! This ain't the 50's anymore!

plugs and leads were renewed when I replaced module last time along with cambelt and water pump when I rebuilt the top end. points are cheaper to replace than faulking out $300 every 18 mnths which is why I want to put points dizzy on

ok you also need the rest of it like the other coil . best to take it all off on a whole engine as it was and transplant it over.

Normal coil has + and -Negativeto Dist,12v from solenoid wire, or appropriate place on ign switch to positive on coil, 12v from ign switch to ballast then ballast to positive on coil. That's how I would do it anyway (o:

Get a diesel then theres none of that shit to put up with

depending on the fueling and inlet manifold setup you may not have sufficient vac to run the vac advance, '94 may actually do it - you may need to drill the inlet after the throttle plate to get the proper vac point if there is not already a port you can use

12v from ignition switch to resistor ( 3 to 4 amps max, you maybe able to use existing wiring or just run a feed from the ignition fed fuses)( if you are using a resistor coil) then to coil +, coil - to points, put a lead with a diode in it from solenoid switch connector to coil ( bypasses resistor when cranking = 12v ( or as good as12v allowing for starter reducing battery voltage) = easier starting ) any old diode ex an alternator will do - check it is not blown and allowing current both ways and then solder it into a wire so current can only flow from the solenoid side
set static points as about 8 degrees BTDC, you'll soon know if it needs more,vac tube from port in manifold to dizzy and you should see the spark point move as you lip the throttle
fairly basic setup and you may lose a small percentage of the power - its a 94 galant so you maybesurprised at how different it is once you get a good system running

Sounds like an up sell! lol usually Test the leads first and check the plugs &then replace only what needs replacing.nothing more & nothing less. modules can pop for other reasons , incorrectly fitted ,poor quality part ,heat transfer & voltage reasons . find the cause first , and fix only that as required

Cheaper to keep changing whole dissy with second hand.
