For those of you who have done a HID install, what is your idle voltage? I'm using a 35W ballast and my voltage at idle dips to 11.9v. the grom is ridden almost daily so the battery should be good. i'm currently doing a trickle charge overnight to see if that helps.

I have had a hid for a months and no charging problems I have not charged it once, my voltages is the same at idle .. , and its been riden almost every day... As long as you don't idle the bike for hours you will be fine ( actually drained battery longtime ago tuning and idling a lot ,I had to bump start the bike but with a mile down the road was already charged enough by the stator to start the bike). As soon as you rev the bike the voltage should go up.

my voltage does start to increase above 3000 rpm and eventually surpasses 14v. just not sure if the low idle voltage is normal or if i have a fault somewhere.

Where are you tapping the Hot voltage from, the rear tail light HOT wire or ??????

 

[pwr2wh8]

taping switched 12v from the rear tail light which triggers a time delayed relay. the relay is wired to the battery (fused) for it's source of power.

btw, i'm measuring the voltage across the battery terminals.

browsing around the web, it seems the grom in general does not charge the battery while at idle. anyone who has stock electrical willing to measure their voltage at idle?

You are over thinking this, i bet your grom is 100% fine....... if the battery dies which it "WONT" then i would worry about this...... Just ride the grom like you stole it and dont sweat the small stuff.....

 

[pwr2wh8]

probably. now i'm just curious what the idle voltage should be. if the grom does not charge at idle, then i would assume battery voltage.

as i wanted to monitor my voltage, mainly at idle, i got a gammatronix tri-color led volt meter.

more info here:

as mentioned in that thread, my battery is discharging until around 4k rpm's. if normal for the grom, this meter will be helpful so i know when i have to hold the rpm's up to help charge the battery.

Most every bike has a "break even" idle speed at which the revs are high enough to charge the battery. Discharging slightly at idle is normal.

my double led bars also i believe have a high draw... i have unplugged the relay during the daytime, and hadn't needed to charge my battery at night.

the days i leave the relay connected so that my headlight is ON, if i dont trickle charge it overnight, within 2-3 days... i will be bump starting my grom.

annoying, and i haven't figure out a way to fix it

yup. i know it's normal. i just like to know how low the battery is so i can maintain higher rpm's when needed.
