have now changed my front turn signals to bullet vintage type. they arrived with 8w bulbs which Ive learnt dont flash on HD's so I changed the bulbs for 12v/23w (the rear ones are 21w, 23w is the closest i could get locally).
they flash at idle but when you put on revs they stop flashing & just stay on.
?

thats a tough one, revving it shouldnt make any difference to the voltage unless the regulator is stuffed, chuck a volt meter across the battery and measure the volts at idle and when you got a fist full. let me know what happens

thanks for the advice dude, I dont have a light in the shed so will try that tommorow. Am I checking to see if the volts increase when I rev it? and how much they increase?
should it put thru a stable charge all the time regardless of revs?

at idle it should be around 12v and at revs it will stabilise around 13.5v -14v ish, the volts will drop as things are turned on too, try with nothing on then hit the high beam, brake light and hazzards to load up the alternator.

You need to put some resistors in the wiring to the indicators,I can't remember how many ohms but dick smith has them.

i thought that was only with LED's? they draw less current

r u sure Doug? cos I have put 23w bulbs in the lights. 21w is stock, so surely 23w draws enough power to not need resistors

before i had 21w in the back & 21w up front & everything working. now i have 21w at back & 23w up front & have this prob. surely dont need resistors with this setup?

could be a bad ground if it flashes the brake light

sorry, my bad on how i explained that - what I meant was, when I apply the brake, it made the indicators flash instead of them staying on without flashing.

yeah thanks - cool looking, but I hate having to wire those resistors in, they seem to take up a lotta room. apparently u can wire one for left & one for for right on Sporties, instead of having to put in 4. Then I have to hide them somehow grrrr
I think, that Sportsters flashers must be programmed for 21w only. I have 23w bulbs & they will only flash without the motor going, so Im assuming it thinks that there's not enough current draw once the motor's running, to get them flashing. how freakin ridiculous. i usually love Sportsters, & harleys in general, but this 21w setup really annoys me. i mean, how stupid, for a model that is almost bound to be customized, to have such an anal setup.
& there doesnt seem to be a 12v/21w bulb in existence in that small size - only 12v/23w. go figure.
im gonna put it back in the shed & wire in the resistors another day, had enough for the moment. time to get into doin a 450 rebel bobber now. the 23w bulbs work in those Smile

Let me know if you get some cool looking ones like that, but take less fuss to get working on a 12v system haha

Heres the easiest way to solve this prob, pull the ugly things off all together, zip tie them on for a wof, tear them off again.

people tend to give way if they see a big tattooed arm hanging off the side of the bike rather than tiny little orange flashing things

LOL.
hey I only 2 tattoos left. 2 were removed with laser. that was more painful than tattooing so i gave up & left the other 2 on.

The easiest way to fix this is fit a non load sensitive flasher unit Narva make one in 2 or 3 pin should be able to get them through Repco, the load sensing is only so that If a bulb blows the flash rate increases so you know somethings wrong, Ive found that fitting 23 watt bulbs can cause the thermal type units to play up.

if only it was that simple scotty, the flashers in these sportys are all solid state, they have a turn signal module with about a thousand wires coming out of them

In that case then ya farked, No not really, you will have to fit resistors across the two 23 watt bulbs to make the flaher unit read the correct load the same as you had to with the leds you fitted Brett, that should sort it.

Yeah Slaytanica's right, i think about 7 wires, yeah will do Scotty, cheers for the help mate
