For helping keep this great

on the Internet for over 30 years! and not clogged down with Ads! Again, thanks! | | | | Joined: Apr 2012 Posts: 68 Shop Shark | | Shop Shark Joined: Apr 2012 Posts: 68 | So this seems really odd. When my 1953 3600 is idling the headlights and stop lights work great and are bright. But the Turn Signals won't blink unless I slightly increase the RPMs.
Can anyone think of what might be causing this odd situation??
Thanks all,
Dave

I get the same response from the Turn Signals whether or not the headlights are on. I was thinking of trying a new flasher since this one is likely the original.

At the lower voltage they did not operate. | | | | | Joined: Apr 2012 Posts: 68 Shop Shark | | Shop Shark Joined: Apr 2012 Posts: 68 | Sorry, I know I'll sound stupid but does "poorly sized lead" mean that the wire is not the proper thickness?

Lower wire gauge number is thicker wire. | | | | | Joined: Mar 2002 Posts: 9,115 'Bolter | | 'Bolter Joined: Mar 2002 Posts: 9,115 | Actually my memory is now providing more details! I did notice at the time that my friend's truck had quite a voltage drop on the supply to the blinker. In the end though the wrong set of filaments were connected to the rear blinkers. Once the brighter heavier filaments were connected to the blinkers, the problem with them not blinking with the motor stopped, went away. | | | | | Joined: Apr 2012 Posts: 68 Shop Shark | | Shop Shark Joined: Apr 2012 Posts: 68 | Thanks everyone! I'll first try switching the flasher (it's on the way) and then,if no success, I'll move to the wiring next. I'll report back later

Now they even work when the truck is not running (previously this wasn't the case). And, the indicator bulb on the turn signal knob also started working again. So lesson learned: those Flashers can keep working but degrade in many other odd ways.
Thanks to everyone on the topic for sharing your wisdom!
