1150GS starting problem?
Any ideas on this intermittent problem:
Bike's a 2001 / Y-plate 1150 on just over 48,000 miles. Up until now, all's been well.
Sometimes when you press the starter button, nothing happens - no clicking solenoids, no signs of life whatsoever? Other times it fires up immediately without any need for the fast idle lever.
I know the kill switch is fine as I can hear the fuel pump primin the system every time I turn it to RUN.
I've replaced the entire r/h switchgear with a used example in good condition, problem still persists?
I've swapped the starter relays over from another bike, problem still there. At the time, the bike would not turn over with either relay fitted yet the other bike fired up with either relay fitted a few seconds later.
Fitted another complete starter motor, no improvement?
The bike normally fires up when cold i.e. in the mornings & when it's time to leave work but not all the time. There seems to be no pattern to the problem.
Bike's also fitted with a Datatool alarm, I had suspected that the immobiliser function was cutting in when it shouldn't but doubt this is the case as the fuel pump can be heard whirring away every time. I was tempted to disconnect the alarm but it's well spliced in to the loom, I'd probably do more harm than good.
Any suggestions - load shedding relay perhaps? I've had the multimeter & wiring diagrams out and have been unable to find a broken wire etc. Both starter motors turn over quick when it does start & the battery's in good order.
All help appreciated
Thanks in advance.
