Turn signal goes out at "high" load

No other part is affected (blower, headlights, wipers all run as they always do). Hmm, will go flasher hunting in this case. :)

@68gtxman: I don't know if the voltage regulator has been upgraded by the previous owner(s). As I'm quite new to this, how would I indentify it? Oh and thanks for the welcome! ;)

Cheers!

Do yourself a favor and get the electronic flasher.
They don't slow down when the voltage drops, because they don't rely on load and voltage to flash.

You won't be sorry. :D
