Model A 6v pos to 12v neg for a RETARD

Hope I don't offend anyone there! I'm referring to myself.

I have a 29 A that I want to convert to 12v negative earth. I have swapped bulbs, headlights etc. I have a 12v coil ready to go. I know switches are generally OK with the change and starters seem to cope as well. The only electric gauge is an ammeter, so I figure that should be OK too.

It was running a Delco alternator when I got it. Do they care if it is 6 or 12 volt?

So I connect the coil for negative earth, what else do I need to change or swap polarity on?

Thanks

Pete

Thanks for that. I'll have a read. At least I know how to read.

 

OK. For anybody else doing this conversion I read through Cherokee64's link. Good info. Things I need to also do according to that link: change to a 12 v solenoid on the starter, reverse the polarity of the wiper motor (and heater fan if I had one), replace the condenser with a 12 v one. I'm off to the shed.

Anyone happen to know what 12 v solenoid interchanges with an A model starter?

Thanks

Pete

 

The condenser is not voltage specific.

Just getting a 12V solenoid may not work. 6V Ford solenoids get energized when the small terminal is grounded by the Ford starter ****on. a 12 V Ford solenoid is energized when 12 Vs is applied to the small terminal. The 6V unit is supplied with power internally where you can't see it. If you go with a 12 solenoid you will need a 2 terminal starter ****on and some wiring to supply the small terminal with the 12volts when the ****on is pushed. It's very easy once you know what is required.

 

Thanks Tommy. I had a look at the condenser and even checked with my local auto elec. Dead right I don't need to change that. I also had a look over on Fordbarn and lots of those guys have had no problem leaving the 6v original and running 12v. I'll give it a try.
