Returning Visitors
If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.
If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.
It will not hurt anything and might solve the problem. See the "GS Charging System Heath" in my signature

Hi,
You must ensure that all of your electrical connections and grounds are clean, especially in the charging system wiring, the fuse box, the ignition switch, etc. Corrosion and rust cause extra resistance which can make your regulator put out more voltage to overcome the resistance. In addition to Mr. posplay's excellent guides, see the Electrical section of my website for tips.
Thank you for your indulgence,
BassCliff

how many volts is the norm for a head light? 13.5 still to much at 4000 rpms?
The manual says that charging can be as high as 15.5V although the battery will probably boil.
Dumb question, but did you touch the bulb?
That was an interesting reply.
It only applies if the bulb is halogen-equipped, as a standard-filament bulb will normally not do so, but it is certainly true that the halogen-type bulbs will blow due to the oil deposited on the glass from simply touching it with bare fingers: the oil superheats, the heat weakens the glass, and the bulb breaks.
14.5 volts is a bit high for charging output. Even your battery will object if that rate is sustained.
Follow the tips already offered.
u could also do a search

it is a h4 bulb i whent through 3 so far. no i didnt touch the bulb. and all my wiring is new
May be a dumb ?..But why is there 14.5 volts AT THE HEADLIGHT? thought the voltage GOING to the builb should be 12 volts. And 14.0 to 14.5 CHARGING voltage is within the acceptable perameters. Wouldnt 14.5 volts going to the bulb naturally burn it out rather quickly??
The lights will see the R/R(+) output less whatever the voltage drops are to the lights. Most 12V lights should be designed to tolerate 14.5V as normal.
Yes, sustained high voltage will cause premature burn-out.
Bulbs should be able to handle that voltage, but the original post says there is ABOUT 14.5 volts at the headlight, so it may be more than that at times. Check the output at various RPMs. You may find it varies upwards into bad territory.
Take a look at the battery liquid level and see if it is going down too quickly, as getting 14.5 at the headlight (after voltage drop due to connection loss) suggests an even higher number at the battery.
If three bulbs have burned out, there appears to be a problem with either the voltage level or a ground fault that causes intermitten surges.....or both.
