Oh my gosh. You may have the worst electronic distributor ever designed. The Mallory Unilite deserves every bad thing said about it. You can blow a module in a heartbeat and be dead in the water without a replacement. The added insult is the cost of the module. Try about $90.00. That's almost half the price of the whole distributor. The theory is simple, as it is just an optical interrupt, but the voltage operating range is so narrow that the vehicle can easily exceed this range and self destruct the module. I switched to a Ford Duraspark distributor controlled by and MSD 6 box and have never been more happy. I sold my new Mallory Unilite with a blown module to a guy who stuck a Pertronix device in place of the module. Good Luck.

the ? of all times
 
i have a mallory disty. and promaster coil. and im trying to put it in a 82 mustang 5.0 . i have 3 wires that come off the disty, (red +), (green-) and a brown (ground) . do i need to use the factory control module? if so how do i wire it to the coil.
because i have another 82 not riped apart i see 3 wires from the module to the stock disty. adn on the other side of engine is the coil with 12v going to it from ignition. what am i doing wrong?
i have tryed alot of ways to hook this thing up but no spark.:confused: :confused: :(

Really? I have been running a Unilite for about 4 years without issue. Optical pickups have less variance in timing from cylinder to cylinder than magnetic.
You are probably generally right about Mallory. Their products have never impressed me as being good quality. Personally, I have had good luck with their products.
I have recently purchased an MSD billet distributor with a mag pickup just because my current dist. is getting old. This will be a good match with my 6A.

Just my 02.

yep
 
had to buy that thing today. i checked the optical in it and it was shot. no drop in current. $90 is to much i think im going to replace it. is there any exer system to run? like less wires the better.

mallory unilite
 
anyone using the unilite should have the mallory power filter installed. this protects the module from power surges. i`m using a unilite for the last 6 years trouble free. with a power filter.

robsampson 10-31-2003 11:43 AM

what is the price and ware can i get one? can you give me a link to one?

FASTFORD 10-31-2003 04:26 PM

unilite
 
Summit racing..mallory power filter..part #MAA-29351......$33.95 plus shipping.
i also recommend you keep a spare module in the car just in case it dies. most of the local part houses do NOT keep the module in stock. if it would die,your stuck it until you have 1 shipped to you. :sweat:
happy rodding...:cool:

My Unilite module (in stock distributor) has been trouble free for 11 years of service. My second unit installed on another goat is relatively new, its only been in use for 8 years. BUT, the cost of the unit has become too high, and I now install other brands when I set up distributors for friends. But it was a cost problem, not a reliability problem that brought about the change.

my unilite distributor has left me stranded 2 times in 5 years . It seems to last 2 1/2 years in my stang .

I have the spike unit , and the ballast resistor installed to protect it .

Just went bad a few days ago , and im looking on the net for others opinions on the ignition myself .

I see alot of people complaining about it . Im not thinking Im going to spend 110.00 for the replacement module at the local speed shop .

I took the module apart to diagnose it , and theres about 3.00 worth of electronics in there . Theres no reason for the high price they charge .

I found the bad relay on the board , unsoldered it , and went to the local electronics store to buy one . Only way I could buy the relay was if I bought in quantity . 500 piece box 1.85 each .

So .... im now thinking of MSD . But .... they have the same problems !!!! I've seen more complaints about MSD than anyone . Hell , even Nascar keeps a spare box in the car with a toggle switch ready :rolleyes:

So what does a guy buy ??

I have 12 volts going to the coil & into the resistor but no spark! I have a accel
super coil on the car & Please give me some help it was running fine when we parked it. There is a little black box on the firewall (1"x2") with three wires coming out of it. I have no ideal how to check this thing :sweat:
