Hi, new to the forum. I have found a 1940 ford coupe that has been sitting for 6 years. I got the motor freed up and tried to start it. It has a Mallory breakerless dizzy on it. I see that the coil is putting out power, how can I tell if the module in the distributor is good or bad. It turns over but no fire to the plugs. Any information will be appreciated.
Call Mallory they will help you test it. Their modules don't seam to last very long more off shore junk. I have the two bolt one on my 40, and have replaced 4 of them at $90.00 a pop.
"Coil is putting out power"...? Do you mean that you get spark from the coil wire, but not to the plugs ? If that's the case, double check cap and rotor..... 4TTRUK
Hey!! The best thing to do is take the mallory out sell it on e-bay(you will get 200+ for it) get a Bubbas distributor with points for 200.00 and drive the wheels off it!! Thats what I did!! You wont be disappointed!! Pete
For all you Mallory haters, or people who have trouble with their modules failing; don't toss them. The problem is the modules don't handle voltages over 12.5 volts well. If you put a ballast ignition resistor in the 12v. feed to the Mallory you wont ever lose a module, and they'll last forever. If you use a electronic box like a MSD 6A or 6AL ahead of them you'll also be protected from failures, as these clip the voltage and protect the modules too. Mallory sells a unit to protect the modules also, but it's way more than the cost of an $8 ballast resistor, so why spend the extra money to do the same thing.
I have seen people put MSD's in flatheads.....maybe be an option, but I have friends running Mallorys and love them, they were pretty much the first to go big way back when
