coil and cond and rotor crab 6 volt

[Walt Dupont--Me.]

A friend just called me, he has an original 41 pickup, original engine, 6 volt system, he want's to change the helmet dist to a crab, He just ordered the adapter from Speedway, easy question for Babba, what to use for a coil? and if to leave the resister under the dash? and is that RR145 Napa condenser all right for the 6 volt system? How about that coil from a 49-53 Ford and bypass resister? That must have an internal resister to cut the 6 down to 4. Thanks Walt

Walt,

A 49-53 coil should work with a crab. I would bypass the resistor under the dash....

Thanks Babba, I presume that Napa RR145 cond. will work fine with the 6 volt system. Thanks Walt

yep, but the FA54 is the correct unit for the crab.......

Still learning - how do u bypass the resistor?

Why bypass the resistor? Rationale?

The 49-53 coil is approx 1.5 ohm resistance and adding a .6 under dash reisitor is too much.

Attach both wires to one terminal.

Bubba ty - A stock 42 to 48 coil , would the resister under dash be ok then , so if you upgrade to a later type could the ohm value changes. What noticeable changes are there between coils when the voltage out put is about the same

The 42-48 coil mounted on a bracket on the intake has the resister mounted on top of the coil, not under the dash. Walt

A 6v VW coil also works fine as well as any GM 12v coil, they work just fine on straight 6v.

Easy way to solve all this is to check the coil you are using and see what the resistance is.

The resistor on the 42 is still under the dash. As far as I know they moved it in the 46 model. At least mine is still under the dash mounted on the board with breakers for lights etc.
