1100 won't turning over

Helll,

Have a problem. Trying to start my GRiSO, and have only a  click from the starter. Battery fully charged. And once hit the button voltsge drops like arround 3v. Also dash goes off as well. Then one of the relays start clicking. With the jump leads  same story. Removed spark plugs engine is turning over once pushing. Still not cranking from starter. Cleaned battery terminals and ground on the starter. No different. Any ideas?


Also had apmg0022 error on screen

Wet speedo sensor...


Seriously, have you tried jumping the starter motor directly to see if it spins over?


apmg0022 on the dash means the dash is rebooting, which means the battery volts are dropping below ~10V.

Insufficient battery voltage, get new battery
See if it starts w/hot lead from batt  strait to solenoid wire spade connector.

wow typing at same time, Beetles fast

Battery is two years old. It does jold charge. I will try another battery, and direct positive feed to a starter motor. Also after start attempt when dash goes dark battery voltsge floats between 9.5 - 10.7 volts even with ignition off. Once disconecting from bike it goes back to 12.5v

Is your battery a 20AH one or one of the common 16AH replacements? If it's a 16 it doesn't take long for them to degrade to the point where problems will start to occur, they simply don't have sufficient CCA's.

battery is 18AH and 280cc

That is the absolute minimum required and as you probably know not all batteries are created equal.

If your dash is blanking out and the motor is refusing to crank with the relay 'Clicking' before the LCD blanks out these are the classic signs of an inadequate battery. Not wishing to appear patronising but you do understand the relationship between voltage and current draw?

It may well be that you just have a buggered battery. If it has sat for any length of time on a 'Battery Tender' this will probably of been contributory. If you are leaving the bike unused for any period it's actually far better to leave the battery connected to a charger with a timer so it just gets a. Charge top up once or twice a week for an hour or so then having one of these 'Floating' devices that are supposed to keep things happy by being plugged in.

I'm just about to go down the 'Battery Care' rabbit hole as all three of my 'Normally' registered bikes come up for registration in a month from late March to early April! That costs me/us a lot of bunce. Bunce I can't afford as a little old retired person so I'm about to take Yellow Bike off the road for winter and maybe start alternating them all in some sort of rotation.

Sucks to be old and living on a fixed income. Having said that our 'Fixed income' would provide life's basics to a whole village in less happy places in the world so you'll find no complaints from me!

Well battery was of the bike for at least 3 months of winter. Recharged put back to the bike 1month ago had 150mile trip. And now it is what it is. Ok I will try to investigate battery probably will try to start from car battery with jump leads directly connected to the bike terminals, and will see. but if it is the same then what? Starter motor busted?

Take it to a battery shop and get it load tested.

Well i have tried to start with car battery, same thing. Try to connect directly to starter motor from the battery it does spin. Maybe relay on starter motor?

The Guzzi sages are all right, re the GRiSO being fussy if the battery isn't A-1;

My Yuasa had regular charges with a CTek for a couple of years;the battery voltage tested & everything turned on fine;

But it wouldn't turn the engine over & start until I put a new battery in it.

In an effort to make it a more reliable starter I also cleaned the ground, all connections & also swapped in a heavier wire from the starter relay to the solenoid.

If you search for it; I think there's a post, about a factory service bulletin,recommending a heavier wire from the starter relay.

The original wire was tiny 20-22 ga?; I would've liked to have replaced it with much thicker wire; but it's a crowded tight spot to work in;iirc 16-18 ga was what I ended up using.

At some point;I will be changing the battery cables to straight lugs & improve the main ground.

fwiw ymmv

This sounds like a variety of Startus-Interruptus?  
Fix2 is easiest (I did both)

I miss Kiwi Roy's guidance on electrickery; Tks very much for that link,it's all gold!

In that post,you mention a quality battery lug crimper,but the link is dead, do you recall what the brand & model it was?

Affordable decent crimpers are challenging to find here in Canuckistan.

The battery lug crimper i bought may not be high quality but i cut through a couple of test joints and they seemed fused into one mass of metal that would not come apart see here Ebay Linky to "16 Ton 8 Dies Hydraulic Crimper Wire Battery Cable Lug Terminal Crimping Tool"

Crimped connectors are ugly BUT seem to have much better reliability than soldered.  so you need a good (ratchet style) crimping tool for the spade connectors etc linky to ratchet crimper -

Ok lads,
Problem solved. Was 3 issues at same time. 1st solenoid on starter motor was busted, 2nd ground cable was half broken near battery terminal, 3rd battery was busted as well, it had voltage but no power. So replaced solenoid on the starter motor part no ame0012 by magneti marelli, sort out cable and replaced battery and never had so smooth starter run.

Great work! Happy riding!
