I was recently helping a friend install turn signals on his 1946 Ford and once completed, had a signal indicator light malfunction. We traced it to the 6 volt flasher included with the kit. The NAPA interchange number is a Tung Sol #535. Locatged and installed NOS Tung Sol #229D flasher and light malfunction problem was resolved. Has anyone experienced a problem with the newer replacement flasher (#535) causing turn signals not to operate properly, and if so, what was the remedy short of locating a NOS 229D flasher? I did send a request to Willow Run Parts for info stamped on the flashers they sell but have yet to hear back.
Thanking you in advance,
