Turn Signals Not Working

Okay, I've got a pretty much stock '94 VN750. Recently I've noticed that the turn signals don't work about a minute or two after starting the bike. I'm wondering if maybe the draw of starting the bike is taking too much out the battery, leaving it unable to turn on the signals. They usually come back after a minute or two. Also I've changed the light from the original bulb to a new halogen bulb specifically designed for motorcycles, with exactly the right wattage.

Possibly. Do you have the old bulbs? If so, replace one side, both front and back, and see what happens.

I don't know that much about Halogens, but if it requires at least 12 Volts, then it could be the battery isn't up to par like you said. Do you have a battery tender?

Sounds like the battery to me too.... if it is getting that low I am surprized that the bike will start. pull the battery and check your levels, fill and put on charger.. Battery tender, then try it again... next ugrade for you will be a MF battery, go for the Yusua.... if battery checks out, you might have some bad connections, or worst case senario is that your stator may be getting weak. At which point you will want to check the output of your charging system.

You'll find that info in the vulcan verses.

Battery should be okay, it's a new (2-3 months) MF battery (diehard from Sears). OTOH, there could be a problem with the charging system, but if there is, why do the turn signals work after a couple of minutes?

Well I'm not convinced the battery is the first suspect. I suspect the new halogen bulbs. What wattage are the bulbs?
Halogens will draw on the battery more. They are brighter, but at the expense of a bigger draw on your battery. Chances are they don't work in the first couple of minutes while they wait for the battery to recover from the start.
LEDs however in the turnsignals are a lot less draw and actually give you back some battery power over the stock bulbs.
I am all for visibilty but not at the expense of taxing an already fragile electrical system. I bet if you replaced the halogens with the stock 1156s and 1157s you will find they work just fine from start-up to shut-down.
If you want some links for brighter LEDs let me know.

Not to hijack this thread but if you go to LEDS will the 1.85" fit in our taillight housing?

I'd have to go out and actually measure but if you look at the link, there are several other sizes available too. I have the "Tower LEDs" in mine. Not the flat lights but an actual tower with LEDs on the sides and top

These "out bright" the stock bulbs!
The links are just a couple of options. Switching brake and turn signals to LEDs creates less of a draw on the electrical system, last longer and with the new bulbs are just as bright if not brighter than OEM.

I think you're right. Halogen lights are more sensitive to voltage drop than incandescents. So until the system voltage comes back up, they aren't going to work too well. They probably just don't work when you're stopped and the bike's idling. But work ok while crusing.

Aww, who needs turn signals when your stopped? Just use hand signals - it's hard to miss those. If it's at night, strap a small flashlight to both hands and wave them.
