Tri-Spark Power 4-volt Single Lead Coil
Perfect for 3-cylinder 12-volt system (requires 3) Tri-Spark, Rita Kits etc for Tri/BSA III analog ignition kits
Tri-Spark coils have extra windings using heavier wire and a high grade core for improved spark energy and duration.
More than double the spark duration of the stock Lucas coil.
55% higher spark intensity than most common competitors.
Longer spark duration, and higher intensity make these hard to beat.
1.0 ohms
Spark duration is desirable for easy starting, especially on cold engines where fuel mixture is the most varied.
High spark intensity minimizes the change of misfire, reduces plug fouling, and can make the most of high compression engines.
Individually inspected and tested to ensure they meet all specifications, the appearance and dimensions are the same as
the later Lucas type coil (17m12, 17m6).
The aluminum can takes well to polishing and will yield a bright chrome like finish with minimal effort.
Warning - These coils discharge with a very high voltage so extra care must be taken to always have a spark plug connected to the HT output.
A tight fitting rubber cap is required on the coils HT output tower to prevent arcing.
Never under any circumstances operate the coil without a spark plug connected.
