First of all, when boost starting a bike from a auto make sure the auto is NOT running. The auto battery has more than enough power all by itself.

The most likely is 4) None of the above. The truck's charging system put more than 30 amps into the bike's electrical system and blew the fuse.

Get a new bike battery and fully charge it. Then go from there. If you really want to see if the bike will run before buying a new battery go ahead and hook up the cables to the truck battery and try it with the truck off.

A faulty alternator/regulator/rectifier should have no effect on the bike actually starting or turning over. Only the output of the charging system would be affected, possibly causing the bike to die when the cables are removed. My '78 Honda would not run at all without battery power, not sure if the Kawasaki is the same or not.

2006 GMC Canyon with >200k miles, 2nd owner. Vehicle does not like to start after it has been running, generally waiting 15 minutes and it starts and runs just fine.

I would bet u have high impedance in your batt. Cables. Ez to check if u have an ohm meter. Put ur metor on the lowest ohms setting. Touch ur leads together, see the voltage reading , like 002 for example. Disconnet the batt. From the cables. Read the resistance from one end of the same lead to the other. If ur reading is more than .002 or lower your cables are bad. Your problem is a classic issue of what you have. Hope that helps.

Won't crank. Replaced 2 new batteries and works for a while. After riding, it won't start without a jump. Solenoid rapidly clicks, then intermittently clicks. I'll get a couple of quick cranks then...

Looks like a problem from alternator ,start the bike then put a multimeter leads to the + and - on the Batt ,you will see the Batt charge:12V to 14.5 V,under 12v then you have an alternator or regulator problem.

Chevy venture draining battery

The alternator is out. The ONLY time your vehicle uses battery power (while the engine is turning) is during start up. After that the alternator runs the car.

With the car running put a volt meter on the alternator. Red lead on the big nut on back side if alt. Black lead on the neg batt cable or a good body ground. Voltage should be around 14.5v DC.
Then still with engine running, red lead to batt postive, black lead to batt neg. Voltage should read the same. 14.5v DC
If not, the alt. Is bad

Yamaha MT03 - shorting / or loss of power

Hi, David check all wire connectors in the ignition and starter circuit and the usual suspects are:
1. Ignition Switch not in the "ON" position.
2. Engine Run Switch in the "OFF" position.
3. Discharged battery, needs to be 12.5 volts or better and be able to pass a load test if necessary.
4. Check the battery terminals for damage or corrosion check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
5. Tip over sensor needs a reset.
6. Faulty ignition switch.
7. Faulty starter button.
8. Faulty kickstand or clutch pull in switch/sensor.
9. Starter control circuit, relay, or solenoid faulty.
10. Main fuse or circuit breaker may be blown or faulty.
11. Check for engine trouble codes.

Bike runs when boosted take cables off the bike dies

bikes need a measurable amount of charge from the battery try getting a new battery or testing the one in the bike with a load tester or cleaning the connections on the battery.

2001 Oldsmobile Alero Power issues

You may have a parrasitic draw, disconnect negative batt cable and place a DVOM positive lead to the batt. post and the negative lead to the batt. cable end and set it to amps, if you have more than a 0.02 amp draw then you need to start pulling fuses to see which ones eliminate the draw.

Key on no power batt good 25amp fuse good

If you ever have to jump start a motorcycle with a car DO NOT have the car running. Having the car battery in series will provide sufficient power to start a motorcycle, but the amps generated by a car alternator will wreak havoc on a motorcycles electrics.
