What voltage should a motorcycle battery read when running?
It should read anything above 12.0v but under 13.2v but ideally between 12.5 – 12.9 DC volts is required. Any less than this, you may start to encounter starting problems as the Battery will not have enough juice to turn the big twin motor over.
How long does a bike need to run to charge battery?
Riding for only twenty minutes isn’t enough to get it charged either. Put the bike on a charger overnight, and then use a battery tender when you’re not riding to keep it charged.
What happens if I charge my bike with little charge?
To little charge will gradually kill your battery. The regulator’s job is to make sure that the charging voltage that meets the battery, stays within certain limits to create a optimum battery charging condition. The specific value of this number differentiates from bike to bike.
How to fully troubleshoot your motorcycles charging system?
Check for resistance or continuity through the stator’s windings: (The bike does not need to be running to do this test) • Set your multi-meter to the resistance (ohms Ω) setting. • Disconnect the stator’s wire harness connector.
What should my motorcycle charger voltage be at idle?
Now you SHOULD begin to see a change in voltage. Ideally, a charging system that is efficiently charging should read anywhere from 13.2volts to 13.8volts DC (or above) at idle. STEP 3. Now what you need to do is read the voltage output past idle by slowly twisting your throttle up to around 3,000 RPM and hold it there.
What causes a car battery not to charge?
Bad earth connection. Its not charging is a broad problem with a lot of potential causes. Check your battery first. Clean the connectors, take it to a dealer or shop or auto parts store to check and charge (or do it yourself). Get a battery tender. Usually batteries are drained by use or by built in equipment such as a clock.
To little charge will gradually kill your battery. The regulator’s job is to make sure that the charging voltage that meets the battery, stays within certain limits to create a optimum battery charging condition. The specific value of this number differentiates from bike to bike.
Why does my motorcycle battery charger not work?
Basically, this does not allow the regulator to send voltage to the battery any higher than 14.6 volts. If the stator fails, your battery will no longer be charging when you’re riding your motorcycle. Often times, a short can happen in the windings around the stator. The insulation on the wires can wear down over time or a wire can break.
How can I tell if my motorcycle charging system is working?
So you have a 130-watt charging system in this example. Now, you can take the wattage of all those electrical accessories and see if you’re under or over your 130 watts and how much you have to play with. You can check your system by putting a volt meter on your battery. Or add a volt meter gauge to your motorcycle.
Is it normal to have more than one bike battery problem?
It is not so unusual to have more than one problem on a bike charging system, and your bike will work better if all the problems are fixed. Please use a GOOD battery. The battery must be fully charged up first, using a bench charger. If not available, maybe you can borrow a charged good battery from another bike.
