Voltage Query

[thopiang]

masters, good day

is it normal that our bike will reach 15V while engine is running?

normally, if headlight is on, my voltage reading is 14.7 or 14.8V, however, sometimes it reached 15V when headlight is off. (reading thru koso digital speedo)

thanks and happy new year

paps, yep, mine reads 15.8v minus 1-2 volts when using hid, but no problem with regards to when using rcdi becuase the good ones (rextor v3, brt) have a wide range of working voltage from 9v all the way to 24v...


during normal modes on the voltage regulator, when not in fast charging mode, the voltage rises during idle and drops when running, in fast charging mode, vise versa when in idle the voltage drops and climbs when running..thats what i observed...

Based on the manual, it must read about 14.1V to 14.9 and 14v is the normal charging voltage.
@TS: sir what meter did you used? Is it analog or digital? and what settings did you used? AC or DC?.

what a question from scientist Sidro,..Sidro live in outer space,...

anyway nice topic,..watch mode.....

i usually get 14.7 or 14.8 volts reading but sometimes it will reach 15v

am using koso digital speedometer and i think its digital nhehehe

dont know if it is set to AC or DC

aw ah. hehehe,, paps I think its ok if you read 15v, since on the manual indicates 14.1v to 14.9 volts?. a 0.1v difference and its not that complicated. And given that the meter you used is not calibrated. "nosebleed ako paps".

ito na lang: wala sya problema paps, maliit na difference lang kpag nag reach ng 15v, unless pumalo yung reading above 20v ibig sabihin hindi gumagana regulator mo.
Oi ronnel tulungan mo ako dito. hehehe

thanks papa sidro hehehe

Koso

Try to replace your KOSO digital speedometer bro, it might be defective... and give it to me...hahaha...

At normal condition, a 12v battery voltage rectifier/regulator should have at least 13.8v output. This output will be held constant at normal conditions simply because regulators are built and designed that way. If the 15volts reading of your digital speedo voltmeter is true, then it is to much.

But anyway try to check your battery voltage output with another voltmeter simultaneously, and then try to compare their respective read outs. Sometimes digital voltmeters reads average voltage..,

hope it helps...

abnormal voltage reading occur when your bike is MAMAW :mrgreen:

@ sir bombie hehehehe, ill try it

@ sir jval, mamaw ka jan hahaha
