Is This Normal - Battery Ok?

Check the voltage on your battery. Give it a good charge. Check it, take it for a run check it, start it and check it's charging over 3000 revs should bring you between 13&14 volts with oand without accessorys on and work from there.

 

Hi Phil heated grips take a fair bit of power, plus if you have lights on additional to the std. bike lights, you'll be drawing a fair bit of current.

I keep my Tiger on charge almost permanently (when I'm not riding her of course) to avoid any battery worries, do you have an intelligent charger you could leave on her?

 

I have similar issues.
I have been on my 1 hr commute, stalled at lights and suddenly not enough voltage to start again.
Yet, 5 min later I park the bike and leave it for the day. When I head home the battery has 'recovered' and starts up no problem.

Please can you confirm the make of battery you have?

I have a Motobatt which has a higher CCA butI think the actual stored juice is lower!
So it is low when in use and then when left a while it sorts itself out/normalises and it's okay.

Check:
(a) voltage before starting lights off
(b) before starting lights on
(c) at tick over
(d) at above 3k revs.

If (b) - (a) = voltage draw - the voltage use when the lights are on but ignition is off is greater than the voltage when (d) - (a) = charged voltage is above 3k revs to then maybe not enough charge is getting through.

I have totally made the above up but it may indicate a difference between what is being used and what is being charged.

I will have to check this myself actually although all he electrics are standard on my bike.

 

Try going for a ride then disconnecting the reg/rec when you get back

Leave it a bit

Reconnect reg/rec and see if it still has life

I had one go pear shaped and sucked the life out the battery when not running

 

That's your problem right there.
