  • New V Twin upside down mailbox coil

    does anyone know how many ohms the upside down mailbox coil draws that V Twin re-engineered in 2018? As i understand it, these new coils have the silver wire nuts (pic attached). i will appreciate if anyone has one of these coils you can put an ohmmeter to and tell me the draw. the coil i was using (unknown mfg'r) quit working. V Twin lists 2 part numbers for coils that look and are described the same and fit same year models, but gives no ohms specs.... pn's 32-7758 and 32-1434. i am running one of Ed Fralick's Beyond2000 electronic ignitions in my '27 JD, the ohm range needs to be between 1.2 to 3.0 Anything less than 1.2 ohm will burn out the sensor. Anything greater than 3.0 ohms gives a high speed miss. Thanks in advance.

    I run Ed's ignition on my '46 WL, 12v conversion. Those coils are NOT 3 Ohm and will continuously burn out on a 12v bike. You will be riding home on one cylinder, often.

    If you are 6v, I have no experience. But on 12v, Ed's ignition fried out at least 6 of those coils. Then I went to a Shovel coil that was rated at 3 Ohms, bike ran great. Right now I have a reproduction coil from a fella in Colorado, looks original and made to work with Ed's ignition, again 12v not 6 v. 150 miles so far, works great.
