Battery question

So my 2004 T still refuses to start.
It turns over ok, throttle closed, cold start on.
New spark plugs, plenty of fuel ;)

Battery has been on an optimate and all the lights say it's ok and healthy.

Voltage measures 12.6 with the ignition on, and drops to 10.6 when I hit the starter, on a multimeter.

My question is ...how can I tell if my battery is to blame ?
Can it have enough charge to turn the crank, but not enough to make a spark ?
Is the voltage measurement misleading ?

Help ?!

When I had that exact scenario (engine turning over, but refusing to start), it was due to:
- Throttle bodies needing balanced. Once I had that done by Griff (AP), it has fired up 1st time every time.
- But if throttle bodies not balanced, unless it starts in the first few seconds, the engine floods. Then it can take 1 or 2 days to dry out the plugs if left in situ.
- A weak battery can turn the engine, but not have enough power to give a good spark, which compounds the problem.

All told, if that is the cause, get a new battery and throttle body balance, and you'll be sorted. Mines a 2004 as well.

HTH's.
 
Many thanks Paul D. I'm picking up my new 2016 TuonoRR and will make sure the dealer has this nailed down for sure before I ride away.
 
Hi, I'm new to the forum but had this 3 weeks ago. I had exactly the same issue. Had the plugs out and all sorts. It was flooded. Cold start off, full throttle (which seems odd) it fired up with a bang after a couple of goes. Sorted!
