2010 Tiger 1050 abs
Bike generally running fine but have started to get some starting issues.
I have upgraded battery cables and a fairly new Motabatt MBTX12U. CCA200
I noticed that on occasion when everything is primed when I press the start button…nothing happens. No click, no whir, nothing.
Maybe if I randomly turn off/on the ignition, or the kill switch, it may start fine.
I thought because of that it may require a bit of WD-40 spraying in the switch, clutch switch, stand switch… Maybe that worked I thought. It did seem to start ok after.
I did notice that, on a couple of occasions this was not limited to cold start, but happened when warm as well - about 30min into a ride I had cause to stop. Upon starting the same issue. Came to life eventually.
This week, when on my morning commute (-7°!!) and starting the bike - Kept in unheated garage, again, nothing.
It seemed that if I kept the ignition pressed for…30seconds, it would try to fire for about a second then stop. I’d have to wait - ignition off and on again, then could try that again . Would try to fire for a second then stop. Repeat.
I had a heat gun on the battery for a few seconds and also just pointed at the starter motor. I don’t know why, thought it may help.
Final attempt… Keeping the start button pressed…30seconds and it suddenly fired and this time came to life.
Ran no problem.
I have been thinking that my battery and cable upgrades may not be good enough and I need a better battery, more CCA?
May be it’s the extreme cold…but it’s happened on the way home when it’s been warmer.
It also happened when engine was warm.
So, could it be elsewhere in the starting circuit I wonder?
I don’t know what that entails though.
Could it be a starter motor? A coil or something?
For diagnostic, what do I need to measure (Voltage) at what location, and expect to see? What should I be checking?
Voltage at battery?
Voltage at battery when start pressed?
Voltage at tick over - if it starts?
