Blowing Globes at high rpm

Been Around the Block
Well i noticed this week that my low beam, park light and speedo light were all out at the same time, i was dreading having to trouble shoot bad wiring but when i stuck the multimeter on it all was fine with no shorts and power to all the sockets. i chucked some new globes in and they all work,
So it would seem with one of the other guys also saying he blew lights at high rpm's that the ace has a random habit of throwing out a voltage spike big enough to blow the lightsat high rpms, . anyone else had the same problem.?
short term solution is not to turn on the lights at high rpm and long term , change the globes for led items that can handle a few extra volts thrown at them.
the other option for a quick fix is a diode or two in series with the headlight to reduce the volts. but then it might be too dim at lower rpms.

i already have an led tail light so that didnt blow, but first stage is the headlight and dash lights to led , then later on redo the indicators as well, but they dont tend to blow as they really dont get turn on at high rpm and they flash so have a chance to cool.

so if you are going to be out riding hard at night i would suggest taking a spare headlight and tail light globe along with a phillips head screw driver to get them open.
 
What type of bulbs were in there? Cheepo automotive lights or reinforced bulbs that are meant for cycles? High vibration will murder normal automotive bulbs.

Otherwise voltage spikes are no good for other electronic parts on the bike as well as the battery, if you have a loose wire or a corroded ground contact through the regulator you can get spikes like that.

Just tossing that out there, I don't own an Ace wish they sold them here.
 
thanks mate, i revved it to half rpms and was only getting 13-14 volts on the meter so it seems to be ok.
the back light and park light were chinese junk, but the headlight was a halogen from the UK , they lasted ok, my brother does auto electrical work so ill get him to take a look as well, but its looked after so the wiring is in good nick.
 
i have blown headlight low beam once...all leds in indicators , tail and gauges. i carry a spare in my bag. the worst problem with stock headlight is the socket is easily broken...cable ties and a drill fixed it
 
cool, im not running the stock headlight anymore im running a 5.5 inch to fit the fairing.
we still arent sure if its over voltge or vibration. so next step is to fit a volt meter in the dash and see what that shows.
 
I've blown headlight 1x.

My dash light went 2x so I replaced with LEDs and that has also blown twice so have given.
 
I've personally had 2xRear Right Bulb indicators Go out.
1xRear Left Bulb indicator

But these where the stock, I guess low quality bulbs, and a cheap old one i had. I've since bought some quality ones (like, 1 $/each ::) ) and been happy ever since.

Also, I believe the bulbs failing (they went almost one after the other like 2-3 days apart) might have also had to do to a couple weeks I had to go through some cobblestone roads, which clearly didn't help.
 
I think in less then 1200 miles I've gone through 3, maybe 4, headlight bulbs. Thought the issue might lie with vibrations as I've lost nothing else, but I have replaced the rear with an LED unit. Have a H4 headlight to fit when I'm home again now, hoping it turns out to be a little hardier or a little better put together.
 
yeah im running a stock battery, its showing 12.9 volts but i will have to pull it out and check the levels.
 
Warm the bike up, then rev it and continue to measure voltage. See what it gets up to. I'm not seeing a regulator in the wiring diagram, so it could be a balanced system. Possible that if the headlight blows while you're riding, the rest of the bulbs would follow in quick succession.

thanks Sonreir, i got 13-14volts revving to just over half
yeah i wasthinking it was weird the headlight and other dash light park light , went at same time, but that would explain it, the tail light didnt go asthat is an led that can handle up to 24 volts.
 
If you need/want a regulator for you bike, lemme know. The one we sell works on the Ace and replaces the stock rectifier unit.
 
thanks mate, it might be something i need to do in the near future,
(and my wife just told me to stop looking for bits to buy for the bike lol)
 
My bulbs don't blow, but they melt the plastic causing the bulb to move and loose connection.

Ordered a whole new unit to fit on the weekend and hopefully enable me to go home after sun down
 
Machined globe mount from reflector. Fitted a h4 retainer section from an old car headlight. See if it works ok. If it is I will post photos
