CMP Coil 6 volts on 12 volts electrical system
 

My FGT has an electrical installation powered by 12 volts. I want to leave it at that voltage since the instruments are too. I would just like to install a 6 volt coil, as the shape of it is very visible compared to a modern 12 volt Coil. I was reading about the installation of the Ford Lynx and I want to know if I can use your electrical system to feed the 6 volt coil with 12 volts reduced.. I used a photo of Tony Wheeler that was the one that gave me clues and I would like to know if it is possible to do it.

Hi

This might help you or maybe not. https://www.fordbarn.com/forum/showthread.php?t=290142

If you are dropping 6 Volts at 4 amps it is 24 Watts which would require a decent sized wire wound resistor and a heat sink . I think Ford used Nichrome wire wound on a ceramic former in those resistors as seen in your pic, the same wire as used in the old electric bar heaters, the resistance increases as the wire heats up. I can see a cover over the resistor in your pic, this is to shield fingers from the hot resistor. Where would you find and buy a Lynx part like that ?

The other issue is some of those Ford ignition coils were rated at 4.5 Volts not 6 volts.

You could use a solid state device to drop the Voltage down but they are rather prone to voltage spikes that destroy them .

Thanks for your help and quick reply! :thup:
The old parts business warehouse that I usually frequent has a good amount of new and closed boxes NOS.
I have to solve some questions with what I find here, since purchases abroad are very expensive for me.
Sending a good 6 volt battery to be manufactured is an artisan task that they do here and they are good but not as good as one manufactured industrially
