Re: Mallory Unilite Module repair
Usually, these modules fail because someone mis-advised a user to run them without any resistor/resistor wire in place, on full battery voltage4s.
Uni-Lite modules want to run on voltages between 6.50 and 9.50 volts, no higher. The way they like is to use a STOCK coil with STOCK resistor in place to the coil, then, the MOPAR .60 ohm resistor between the coil + feed and red Uni-Lite input wire, double resisting the setup.
Over voltage feeding a Uni-Lite will do nothing but blow it up, proven time and time again. These units do not drive any "perf" coil over what a dead stock coil will do, and they do not like excessive plug gaps, they fail when the gaps get above .035 maximum.
Uni-Lite units are the best drop-in units there are, but, they need to be resisted correctly to 'live long and prosper'.
