Hi Guys,

I want to replace the coil, it's fine but I'd like to place a new one, then make this a spare for longer trips. It's been in there for more than 20 Years.

How do I identify what it s for replacement? What kind of coil can I put in? How can I tell if my coil is ballasted? Voltage?

It does have a Lumenation ignition.

Help appreciated, I'd get a new one today before heading up to Vermont on Thursday.



Cheers, Alan

Alan,
That looks like the standard Lucas coil. It might have a part number on it somewhere, but the label may be gone after all these years. Looking it up on SpitBits shows DLB102 as standard.
All the best,
Paul

My coil is ballasted, I have 6-8 VDC on + with the ign turned on.

coil has numbers on the bottom.

If the electrical system is original you have a 6 volt coil. Usually sold as a 12 volt coil w/ external resistor. There is a resistor wire in the car's original loom.

See if there is a pink wire with a white tracer and more importantly - inspect it to see if that wire has been trimmed by a DPO. The factory cut it to a specific length. If there is any doubt replace it with an external resistor or eliminate it and go 12v.

Agree with Doug here, I have learned to hate that pink and white wire :-(

Calvin, Al & Doug,

Thanks guys... I'll check it with the ignition on and off. I thought the Lumination ignition might tip you guys off as to what coil I have..

What do I have to lose by the elimination of the resistor wire and replacement with 12v coil?

time removing the wire, but you could have a 12V coil on a ballast system and it still runs anyway.
check the ohms. pull the wires off coil's + & -, then meter between them, 1.5 or 3.0 ohms, (+/- .3 for meter correction)

There is an overall drop on the system as the starter motor is cranking and in cold weather feeding 12v into a 6v coil gives you an extra boost.

Unless you have a very old battery and use your car in freezing temps I doubt you will notice any differance in starting ability.

Other than that, 12v ignition is simpler with less to confuse or fail.

So here's what it looks like and you can see why I want to clean the area up...

The blue cylinder?. It has a black wire which is NOT terminated, just a spade tip hanging in the air..

No sign of pink & white.. I do not see 12v in any condition... Ignition on or running etc.

Alan, in addition to pink and white wires I also dislike crimp connectors and wires with non standard colours.

Personally I would aim to clear everything out and start from scratch using an appropriate mix of coloured wire from wiring diagrams, going back to the ignition switch if need be.

Produce your own custom diagram by whiting out resistance wires you might no longer have.

If you look at early diagrams (pre resistor ignition) it really is quite simple. And if in a dire situation, you could always Hot Wire the coil direct from the battery as a 'get you home' measure.

Agree with Tony. Each connection is a potential failure. Best to start over from scratch.

One white wire from the key to the + side of the coil and one white with a grey stripe going to the tachometer and another to the points in the dizzy or the output from your electronic ignition.

I have a after market ignition system, 2 wires are connected to the coil with the harness wires.

The starter solenoid has 2 sets of 2 wires connected to the relay coil terminals, where those missing colored wires are found.

The blue cylinder is a condenser. It is used to filter out radio interference. I would just leave it alone.
