I'm running a standard 2.0 pinto engine which i'm using a points/condensor distributor, i replaced the electronic one because i had of a lot of trouble with it, do you think i will need a ballast resistor ? or will a 12 volt feed direct to the coil be ok ?

I'll probably get an after market type electronic set up but just want to know if what i'm doing will be ok for now

weather you need a resistor or not depends on what coil you use,keep it simple and get a "standard 12v coil" the electronic one wont work with points btw.

merlin motorsport at combe sell ballast resistors at a reasonable price if you need to feed the coil with 9v & not 12v

The reason for the resistor is to make the points last longer. 12 volts for start, 9 volts for run.

The reason for the resistor system is to give a stronger spark when cranking. Resistor coils operate at around 9 volts. Battery voltage is applied to the coil when cranking , on releasing the key from the start position the feed is then through the resistor reducing the voltage to approx 9 volts . If you have problems starting then check that the starter solonoid has a take off terminal giving battery voltage when cranking. Normally a small terminal on solonoid. It is possible to get over not having a take off using a relay

Right that's sorted, 12 volt coil, keep it simple, like me

Thanks all
