I see there are wires to connect to coil and ignition. But how does this ignition charge the battety and run lights in a stock harley?
A shopper on Mar 26, 2019
BEST ANSWER: It doesn’t it’s an ignition not an alternator
will this work on a 110 screaming. eagle with. a crank sensor and doo. I still need a voltage. regulator how. does. thee. battery. stays charged?
Robert w on Feb 28, 2019
BEST ANSWER: The ignition is seperate fro the charging system.
Power to the battery comes from the stator and rotor assembly on the end of the crankshaft to the regulator then to the battery.
Turning the key on sends power to the the stand alone ignition which sends power to the coil and from there to the sparkplugs.
When i was young I bought the Harley manual and read it twice and probably keeping old shovelheads allive for my friends and I.
Doesn’t end there. Information was missing so I got the huge Chiltons book of motocycle repair, still shit missing so i got the haynes manual and lo and behold
I had all the solutions.
Good luck on your ride thru this word.
PS it worked on my 103 Twin Cam.
Whats the coil rating?
A shopper on May 5, 2018
BEST ANSWER: This is a single fire coil with a primary resistance range of 0.5 to 3 ohms.
Does this unit work with the crank sensor on my 04 dyna?
