poor battery VS Starter issue

2135 Views 15 Replies 8 Participants Last post by  Fanaticalkilla
2017 Strom 650. Volt meter shows 12.68 battery at rest. Headlamps and lights well lit. Upon trying a start all I get is a very rapid clicking and a sorry attempt at the engine cranking over. Replace a battery with 12.68 or is this a starter problem? Can jump off my car battery and runs well until shut down. Battery tender shows full charge. Just 13K miles. Just priced a battery! What happened to pricing!
Any assist much appreciated.

Repetitive clicking from the starter relay sounds like the voltage is dropping too low. If it starts fine with a car battery, it sounds like your battery may be toast.

It may be useful to measure your battery voltage when its trying to start, or if you can get it to someone with a proper battery tester (like an auto parts store!)

Starter relay could possibly be weak but most likely the battery is toast.

Google "how to test a motorcycle charging system"
It's very simple and can be done with a $20 digital multimeter.
There are a gazillion Utube vids
Your battery may be toast but don't start shooting parts at your bike it until you know what is wrong.

Start by checking the battery terminals are clean and tight.

Using jumper cables can bypass loose terminals.

12.6 should easily start the motor but that is a standing voltage, thus it doesn't mean very much.

If it starts off a jumper there is a good chance there is no problems with the bike besides the battery.

Try the Rolex left hand start.

Push the start button with your right hand.

Turn the key on with your left hand

Pull in the clutch lever with your left hand.

This will start the bike without the headlights coming on giving you a little extra power.

First, I'd make sure the battery terminals are clean and tight. Unhook them, clean them, hook them back up, try to start. Difference?
Second, I'd removed the battery, take it to Advance Auto, or AutoZone, or such, and have them load test it. It may have a weak cell and be on its way out. It might have a good reading at rest but just not have the amps to crank the engine due to a failing/failed cell.
Third, your '17 may have an onboard voltmeter. If not, put one on the bike. Easy to install one to a switched circuit. Either way, you need to be watching your voltage as you ride.

Under load it barely registered 3v. New battery on today and roars to life like a newborn. Thanks all for the helpful input.

Voltage under load is a far more revealing test than resting voltage.

Even some cheapo multimeters can record and recall or display the high and low voltages. This is not a cheapo meter, but it shows the method fine.

The problem with that video is if the starter is bad it can pull a good battery down past 9.6v and may not start the car

So if you follow that video you may replace a battery when you should replace a starter.

Or your charging system is not charging your battery. Once again, test the system.

No test is a complete test. But he had ruled out a bad starter b/c it started with enthusiasm using jumper cables.
This is how I test a battery when I don't have my load tester with me.

Some of the numbers I will quote are just numbers I pulled out of the air; every battery will be different.

This will work on cars and bikes and only requires a voltmeter you trust. (for a car substitute headlights for ignition)

It is best done after the battery has sat for a while, it's more accurate if the standing voltage is not above 12.8v

Hook up the VM (voltmeter) to the battery and take note of the reading, it should be around 12.8v

Turn on the ignition, the volts will drop because of the headlight load, take note of the reading, could be around 11.8v depending on the load and battery size.

For this example we will use 11.8v.

Wait and watch the voltage slowly drop, you want to burn off about 0.4v-0.6v

You now have a reading of 11.4v-11.2v at the battery.

Turn the ignition off and watch, there will be a quick climb in numbers as the load is shut off, this should be 12.8v minus the 0.4v- 0.6v we burnt off.

Then the volts should slowly climb back up towards the 12.8v we started with.

A very good battery will climb back up to our starting point of 12.8v

A good battery will climb to around 12.6v.

A weak battery will not recover the 0.4v-0.6v that we burnt off.

With a bad battery the numbers will continue to fall.

A 12.8v battery has 6 cells, for each bad cell you will lose approximately 2.1v

You right, on load test, V @ 3.4. New Batt on and fires up! Thanks..

Glad you got it figured out.
