Here in the video below i show you one of my favourite tools for faultfinding it can be used for a lot of things , for example testing coils , injectors and solenoids.
In my opinion for the price of the its a must have tool.
An oscilloscope is an excellent tool for fault finding and can show you reading of signals from sensors and injectors , well worth learning and ill add more videos and tutorial on there use as i go.
In the video below i connect the leads to the 2 pins of the pick up coil and turn engine over it give out a nice even pattern or waveform, which means its work as it should.
I had to remove a fuel pump today so just a quick post on doing it as these pumps go quite regular job on motorcycles these days.
Remove the allen key headed bolts
remove the pump from the tank be careful of the sender units float
The fuel pump itself
Refitting is as easy as taking out just make sure the seal
below is fitted correctly .
i would then fit pressure tester and fit to bike to line test pressure
Battery keeps going flat .Make sure you have a good multimeter
you need a good battery it a must buy good quality , especially with newer motorcycles as they have no back up kick start , which is a step backwards in my opinion .
- Battery faulty or worn out , replace battery after checking voltage levels , fluid levels and specific gravity .
- poor terminal contacts ( happens a lot )
-excessive load ( remove some of them lights , stereos whatever )
-faulty ignition switch
-alternator stator coil failure ( test for open or shorted coils )
-faulty wiring ie short on loom or loose connections (check wiring and contact clean all connector blocks )
- faulty reg rectifier
-wrong battery size
YEC-40 Battery Charger - buy on Ebay UK or Amazon UK
YEC-8 Battery Charger - buy on Ebay UK or Amazon UK
I only use NGK why because it what i have always used and trust and i get them cheap trade supply
as i am stuck with them i am sure the other brands make excellent spark plugs but you tend to stick with what you know and trust .
i have had failed new spark plugs in the past though , which does not help diagnosis at all !! .
get loads more info on spark plugs at NGK website here .
checking battery and charging circuit on a motorbike is easy .
first remove side access panel .
test battery at 12v , then start engine and voltage at the battery terminal should rises to around 14v no more than 15v .
