Turn Signal/ Flasher

[lkammer]

 I recently got my dads 1988 FLHTC. when I go to put on left or right turn signal I have to hold the signal switch down and the turn signal only flashes every 3 or 4 seconds. Or I can press it manually to make it flash quicker. Does that sound like a flasher issue?
Secondly, if I want to change to LED rear signals do I need to change anything else besides the light conversion kit?

1992 was the first year of automatic flashing and self cancelling turn signals. Before that, the button had to be held in to keep them flashing. Slow flashing, I can't accurately say. Usually a bad flasher results in fast blinking. On your year, there should not be any special requirements for LED lights, remember they have + and - wires.

Is your battery & charging system in good order?  Connect your car battery to your bike's battery, with booster cables, no engine run & see if they flash any faster. If they do, it's likely you have a battery/charge system fault. HTH.

My '91 Softail had both. Maybe it was a late model year build

If they flash faster with auxiliary power hooked up, don't be too quick to blame the battery or charging system. It's an older bike so pull all of the bulbs & shine up the contacts & sides a bit, in the holder too. Before you put them back in smear a little dielectric grease in the contacts & sides (that's where many older styles make ground contact) & see how all goes.
