Side stand switch

[cndhavok]

Good day all

Cant seem to get any spark on my r1100s -

I was able to get it to start once - I was playin witht the side stand up and down...

Is there a way to "bypass" the swtich to see if its the problem?

[darstardly]

If the bike is in neutral it shouldn't make any difference if the stand switch is playing up only when you click it into gear

its in neutral - but no spark- hmmmmm

Classic hall sensor failure? Try this...http://advwisdom.hogranch.com/Wisdom/oilhead_hall_sensors.pdf

that is what I though - but when i turn over the engine with a spanner on the front pully - it sends the signal to the fuel pump to go so i expect its not that?

[Guest24]

If you have the sidestand up and hold the clutch in, will it start?

[sgoodwin]

Do you mean the injectors as the fuel pump should come on when you turn the key and kill switch on.

Sorry turning the pully the fuel pump cycles -

Clutch in - Sidestand up - no start still

I installed a laser chip a while back - and it worked flawlessly - i have heard if the motronic is not working or the chip is toast - the pump will run continuously.

true. also happens if you end up installing the wrong chip -an issue if you're riding a 2001, as there was a manufacturing transition date of June 2000 from one chip to another.

what year is your bike? might make a difference in the diagnosis.

is a 2004 boxer cup rep -

it worked perfectly for the last month - just when I went to work stopped it -- tried to start it again - it wouldnt even turn over -

I replaced the battery - Jumped it - still no go - spark is dead..

[cndhavok]

As a test I took the montonric apart took out the laser chip reinstalled original - no joy.

pump turned on and shut off as per normal....

so stumped

Fuses?

Ok let's back up a little. It's cranking over right. How did you test for spark? And how did you test for fuel flow?

[cndhavok]

To check the spark I removed one plug left side / grounded it - checked while turning it over..

for the fuel - I can smell the fuel - I expect that its injecting ....

[cndhavok]

ok just went out it started! - it turns over slow - and it fired up -
shut it off - wont start.. .then a few minutes later - wont start again... weird..
The starter doesnt sound great - laboring - turning over - with a full battery - and then a few minutes later - it acts like the battery is dead... but it isnt? -

[Guest24]

Time to clean all battery and starter connections and grounds. Starter commuter may need attention, also. DC current likes good connections. If a connection is warm to the touch, it is probably the area that needs attention the most. Make sure there is not additional connector between the battery and the main power/ground cable.

[cndhavok]

hmmm like mind..

I checked the connections - everything is solid and new..

I did put a multimeter to the battery on startup - she drops to 10.5-10.6 volts -

I already had the battery tested (as its new) and they found it was within limits for an Odyssey -

I did a bench test of the starter - it was pulling between 7-14 amps running with no load.. - I also put the meter on the battery at the same time -and the voltage dropped down to 9.6v few times - with no load to turn over i would assume it would drop as much

I am thinking that either the battery is actually toast - and when the voltage drops below 11volts there isnt enough juice to power the coil/plugs..

Or the start is actually toast and is drawing way too much power - hence intermittent starts and hard cranking -

any thoughts??

[Drews323i]

Put a known good 12v source on it and try to start. Jumper cables. If it starts right up you have a battery dropping voltage problem.

[Guest24]

14 amps no load is high. If the battery is new I lay money on a bad starter. Are the brushes arcing and burnt?

[cndhavok]

The brushed dont look too bad -

When I tried to Jump it before... it would start - barely turn over -

When I run the Power direct to the starter - Bypassing the Solenoid she drops a 1.5 volts..
Running though the solenoid - she drops to 3+ volts..
