Default Can i run this Mallory 6v pos ground?

Picked this Mallory up the other day and cant find any info on it as far as wiring it into a stock wiring harness. I don't plan on changing from a 6volt pos ground system. But I don't know how to wire this into my stock harness? Wiring is not my specialty, can you shed some light on this for me?

I would say it depends on whether the distributor is a point-type ignition or an electronic ignition. That would be something to check.

If a legacy point and condenser style, all you need is to have a 6-volt coil, because all you need to do is make sure you get spark to the plugs. I think 6 volt positive ground systems do as good as 12-volt negative ground for making sparks.

It also looks like it has a standard 6-volt generator hooked up, so maybe it is already made for 6V + ground.

Its point type. The man I bought it from had never put it into in any thing and didn't know how it was set up.
I would think a modern dist like this would be set up for a 12volt neg ground system out of the box. But I don't know?

I don't think the condenser is voltage or polarity sensitive. Therefore, all you need is a 6-volt coil and connect it to give optimum spark with negative pulses to the plugs. I think you are in business.

The points and condenser don't care if it's 6 or 12 volt and positive or negative ground. The points do care if you run too many amps through them, so if you use 12 volts, you need the right coil, or need to add a resistor in the coil primary circuit.

With the coil turned on full time it should draw about 4 amps, so you need a 1 1/2 ohm coil for 6 volts, or 3 ohms (coil and ballast) for 12 volts.

worst distributer you could use. China garbage that's why they discontinued them. Better off with a stock crab type.

My understanding is that MSD bought out Mallory and is going back into production with the most popular items first. I need a cap and it won't be available until Dec. I don't know who MSD is or where their country of origin will be.
