Replaces Entire Breaker Plate - Never Adjust Points or Timing Again!
Electronic Ignition Conversion Kit for Centrifugal-advance 8-cylinder Mallory Distributors
THE TIME-TESTED ORIGINAL
High-Voltage Output*
     The  Hot Spark 
electronic ignition conversion kit replaces breaker points and condenser in the 
distributor to provide rock-solid reliability. With the Hot Spark electronic 
ignition, dwell and timing are always spot-on accurate.
    No matter how strong your engine is, you won't get the most 
out of it without a good spark. The stock, breaker points-based ignition system 
uses technology that dates back more than a century - to the Kettering system, which was 
introduced in the 1910 Cadillac. Even though you can adjust breaker points for 
standard ignition performance, they will burn and wear within a few 
thousand miles, long before the recommended replacement interval. With points, 
the timing will drift; power and fuel economy will suffer.
    The Hot-Spark electronic ignition conversion kit delivers a 
strong spark every time and is maintenance-free. You'll notice quicker starts, 
more top end power and a little gas mileage boost. It's as easy to install as 
points and condenser! 
 
Advantages of the Hot-Spark electronic ignition conversion kit:
Replaces points and condenser with solid-state electronics
Set it and forget it - Never adjust points and timing again!
Zero maintenance
Delivers far more voltage to the spark plugs than points-based ignitions - Increased, variable dwell angle*
Reliable Hall-effect technology
Never gets out of adjustment
Rock-steady reliability
Dwell and timing are always spot-on accurate
Increased gas mileage, fuel economy
Quick starting
Smooth idling
Cleaner emissions
Longer spark plug life
Longer engine life
Cleaner engine oil due to less unburned fuel
Longer interval between oil changes
Easy to install
No points to wear, burn, pit or corrode
No condenser needed
Absolutely no points float - zero - even at redline RPM and beyond!
Never worry about drifting dwell or timing again
No rubbing parts - nothing to wear out!
Fits completely under the distributor cap
Stealth modification - maintains stock appearance
Includes everything you need, no external ignition box required.
Works with stock distributor and coil
Encased in high-temp thermoplastic - protected from the elements and oil, grease, dirt, moisture, etc.
Never bother with points or condenser again!
The best investment you'll ever make for your vehicle
Saves precious ($$$) fuel
8-cylinder engines: Coil with 1.5 Ohms or more internal, primary resistance required.
Requires a 12-volt, negative ground electrical system.
External Ballast Resistor: If the charging system voltage, measured at the coil's + terminal, is more than 13.9 volts at any RPM level, the voltage regulator likely needs replacing or a 1.7 Ohm ballast resistor should be wired between the coil's + terminal and the red Hot Spark ignition wire. Too much voltage can damage the ignition module and other electronic components.
Measuring Coil Resistance (and more):
The Hot Spark ignition fits only distributors that have points and condenser, NOT those with electronic ignition installed.
3MAL8U1 - For 8-Cylinder, Non-Vacuum-Advance Mallory Distributor with Points
The 3MAL8U1 ignition kit replaces the entire Mallory 8-cylinder marine 
distributor's breaker plate, along with points, condenser, etc.
The 3MAL8U1 
ignition kit is designed to fit Mallory 8-cylinder, non-vacuum-advance marine 
distributors only; it won't fit distributors with electronic ignition already 
installed.
The 3MAL8U1 "breaker plate" is the same shape and size as the original breaker points 
plate.
The 3MAL8U1 electronic ignition conversion kit must be used with a coil that has 
at least 1.5 Ohms primary resistance.

VERY IMPORTANT -- 
  BEFORE ORDERING: Some distributors of vehicles, boats, etc. may differ, 
  according to whether the stock distributor is still in place or a replacement 
  distributor has been installed. Some otherwise similar or identical engines 
  use different distributor brands and/or different distributor part numbers. We 
  need your distributor's brand name, distributor part number and number of 
  engine cylinders to ensure that the electronic ignition conversion kit is 
  correct one for your particular distributor.
  
  If your distributor part number, normally found on the side of the distributor 
  body, is not among those listed on the relevant web page, chances are, the 
  Hot Spark ignition conversion kit won't fit your distributor.
  
  It's imperative that we know your distributor's brand name, distributor part 
  number and the number of cylinders of your engine. You may need to remove the 
  distributor temporarily, so that you can read the distributor part number from 
  the side of the distributor body. Usually, the side of your distributor will 
  be covered with oil and dirt, so you'll need to clean it to find the 
  distributor brand name and exact part number.
  
  We can guarantee only that each of our ignition kits will fit a distributor 
  with one of the distributor part numbers listed on its relevant web page. 
  Otherwise, it likely won't fit. Hot Spark ignition kits require a 12-volt, 
  negative ground (earth) electrical system.
  
  If you order the wrong electronic ignition conversion kit for your 
  distributor, you'll need to return it to us within 
  30 days from date of purchase. If the ignition kit is in perfect, unused 
  condition, we can accept it as a retuned item, within 30 days of purchase, and 
  provide a refund to your  account, less a 25% restocking fee and any 
  international shipping fees, etc., but only if the ignition kit is in 
  pristine, unused condition. Buyer is responsible for shipping and other costs 
  to return the product for credit or exchange.
