i found all three of my multimeters. i knew i had them somewhere i'm a aerospace engineering student that dose all of his own auto work. the bike is sitting here in parts waiting for another reshipment from Z1. once it's here on monday i will put it back together and check the charging system.
i saw the post about the colors of the bulb. it is always clear just the filament is broken. -> so vibration. still going to check the charging system to be safe.
if it's vibration Rice Paddy is 2 blocks from me hopefully they have the bucket grommets for less then a arm and a leg.
If the system is seeing excessive voltage, the SMALLER bulbs usually blow first because they can't handle the power well. On mine, the instrument light bulbs blow first. Headlights are a lot more resistant to over voltage than the small bulbs.
Headlights are notorious for dying due to vibration.
i forgot to mention that i did have a hid in it at one time and the filament in it became broken also after about a month. the bike will be running today. got the carbs and tank back on yesterday. just need to put gas in and sync the carbs. then I'll check with the multimeter. i have been looking in to high vibration h4 bulbs. if it's not voltage too high then i'll try one of those.
