There is nowhere in the wiring that a short or bad connection can cause this problem | | | | | Joined: Dec 2014 Posts: 19 New Guy | | New Guy Joined: Dec 2014 Posts: 19 | Thanks to all for the help..It was a bad flasher..
Bill | | | | | Joined: Mar 2005 Posts: 155 'Bolter | | 'Bolter Joined: Mar 2005 Posts: 155 | Had to replace the dead flasher on my after-market signal unit within two months after installing. Another bonus of replacing the junk flasher with a decent HD unit like (Advance Auto/Novita EL13/$15.00) is a nice loud “Tick Tock” that is more like original. | | |
