First off, thanks for all the help so far!
Now on to the question,
So my build is almost completed (hopefully) but since I dont have the charge light on my bike anymore.. Iīm abit afraid that the batteru isnīt charging..
To the maiden trip today.
The bike read 12,43V (with engine off) before I started it up and left for my ca 20km ride..
Got back home.
13,14V with engine off.
11,96V with engine on.
Question is.. Am I good to go? Or is there anything else I can check to see if the battery is actually charging?
-
Is the light system on at rest, and while running, or do you manually turn them on? what about other acessories, stereo, gps, seat/grip heat?
if none of these, sounds like it might be ok if all connections and wiring are good. I would put a little needle type ammeter/voltmeter somewhere in the circuit, at least for the next ride.
An indication is if the headlight dims at idle and increases significantly at increased RPM.

Dont understand the light question.. I usually keep the light switch in the same position even if bike is running/not running?
Nothing is kept on the bike.. LED around all turnsignals plus taillight.. no heat anywhere.. no extra weight ;)
A amp meter is a good idea =) Might be worth the extra weight it puts on ;)
No dimming on lights except some small dip when the ignition strikes but thatīs common I guess.. has the same on my Harley

I'm thinking you are good to go. :clap:

Do it! Having it may prevent your letting the battery discharge to an extent that leaves you stalled along the highway during rush hour with a burned-out starter relay.

Did you replace the charge light with a pair of 56 Ohm resistors attached to the blue wire leading to the alternator? If not, your alternator is probably not operating. Schematic of the connection:

I believe that a voltmeter would be a better choice for everyday use.
An ammeter will show the rate the battery is charging or discharging.
A voltmeter will tell you what voltage is present.
A voltmeter will give you indication of a bad battery/dead cell - an ammeter won't.
Note this applies to vehicles w/alternators. I honestly don't know if an a meter is better than a voltmeter for vehicles w/generators...
No modern carmaker puts an ammeter in their cars.
Probably because of fire hazard and the weight/gauge of wire needed - the beancounters had a win-win.
JMHO..

Hi, yes I have a resistor installed, not a pair though. Found one that seems to work

If you have a multimeter you can temporarily wire it up, and tape it or cable tie it to a place where you can see it easily. You can then go for a ride and see what it is doing. I have done this numerous times with cars and bikes.

I was going to suggest Martins tactic, but I didnt want to show how redneck shadetree I really am. I save that stuff for when everyone has tried their methods, and then I come up with something that works.
When I was a kid, I had nearly no tools. Used to remove vw rear axle nuts with vicegrips or a pipewrench (Stilson) (back when they could take a beating) and a 4 foot cheater bar. Learned a lot of ways to get by without.
Built my first "motorbike" with a horizontal shaft engine and angle iron. Had to hide the contraption, and the mower, and reverse it when Dad asked when I was going to mow the lawn.
and we lived on the last block before the bus would pick you up, so I walked over a mile to school. Develops character, which I am! LOL

Now, with tools, I actually love to spend time wrenching.

WARNING!!! Dumb question ahead...
...why didn't you walk the block to the bus stop instead of the mile to school?

me me me...
