Yes. That's part of the ECU self-test.
get battery tested. that happen to me. it was the battery
It is normal for a carburetor to "suck air" when you are starting the engine or while the engine is running. You should stop the engine before repairing the carburetor for safety reasons.
No. If you have enough power for the engine to crank then it has enough power to run the other systems. ALSO..i've started a car with a good battery and replaced it with "unknown battery" and it has stalled the motor. Starter and everything was good. Technically, even if the battery is dead and all other systems are normal this shouldn't happen. Go figure.
Yes it is priming the system
Amps are just a general measurement of electric current in any application, whereas the term cranking amps are specific to automotive / starting battery applications. Cranking amps is a measure of the maximum current a car/ starting battery can produce in normal temperatures for 30 seconds before the battery voltage drops too much.
12.6 volts with engine off. 13.5 to 15.5 volts with engine running.
yes
Yep.
check voltage across battery and the crank motorcycle and run at high idle or ride aound the block and come back and check voltage across the battery again at high idle without shutting down the engine. this will stabilize the battery from the starting cycle. you really want to see around 13.8 to 14.2 volts, if not, could be a bad regulator. if your lights are brighter than normal it probably is. before you replace the regulator, remove the battery and have it tested. most auto parts stores will do this free of charge. if you have marginal cells, the battery will over heat.
A battery can show full charge but it also needs the right amount of amps to turn your car over. Even if your battery is at full charge and putting out all the amps it needs you could still have excessive resistance in your starting electrical system. If your entire starting electrical system is good than you could have mechanical problems in your engine that are making the engine much harder than normal to turn. It could also be that the bushings on the starter are worn, causing the starter to drag and not spin fast enough to start the engine.
The battery has only so much energy available. Headlights use a lot of energy. If you leave them on for any amount of time with the engine not running, less energy will be left in the battery to turn the starter. This is normal and to be expected. The older the battery, the less energy it can store. So if the battery in your car is old, it will make the problem worse.
When a vehicle is turned on the bat light ,oil light, gas light etc. are on!! A normal sight in the instrument cluster!!If after starting the vehicle the oil and battery lights stay on then this is not normal!! On the engine block there is something that is "planted" and is the oil sensor bulb!! Before starting the vehicle check that the oil level is right!! If the oil level is right and the oil light stays on after starting the engine,if you're a DIYfer, first check the wire connected to the "bulb" for any unusual sight-frayed and grounded!! If the wire is alright then you can pull out the bulb and inspect and clean it then install back!! Start then engine.If the oil light goes off after the engine starts then your problem is solved!! If the light stays on,then you can call the shop or a friend mechanic! As with the battery light , try checking alternator belt condition-frayed or slack tension!! If belt and tension are alright then have the alternator checked and repaired or replaced as needed!! This is as per my experience!!Thank you!!!
