Modern Vespa

Hello,
New to the forum. I have just bought a Gilera Fuoco 500ie and have ordered a new clutch, whilst waiting for the clutch I thought I would check levels and tyre pressurs etc. Found the coolant to be low and toped it up and then started the bike up I now have LO in large letters on the LCD digital display and for the life of me I cannot figure out what it is, read the owners manual but that was no help so can someone explain what it is and means and how to get rid of it.
Thanks


LO on dash

The ambient temperature sensor may have come adrift.

Hello jimc,
thanks for the reply, where will i find thid sensor.

Use the search function buddy.

Either the bike is a) trying to greet you or b) ambient temp sensor has expired or become unresponsive. Sudden disconnection is not common but "green death" a.k.a. corrossion particularly at connectors and terminals is. It is a Italian vehicle after all, so expect the electrical system to be about as resilient as a week old salad.

I'll let you decide. Should you decide on "b", then this pic should help

Just incase you wonder its the serrated plastic stud ,it can be accesed from the fuse cover on the right hand side down by your foot. I had the same problem and all it was was a very dirty connection , The problem is as the rear wheel has no mudguard so the rear tyre throws all the road s--t and water over the engine and electrics. The one thing you must do is check for ( The hidden fuse ) i don't know how to do links BUT if you do a search on the MP3 forum for "Hidden fuse "you will get a long list look at Hidden fuse done-pictures and all and Fuoco 500ie not starting , this will tell you all you need to know. O and when you have cleaned everything up cover the solenoid with a plastic bag to keep the dirt off it.

Hello,
thank you sbaert and 3legsofman, found the ambient temp sensor, wire is to short to get to the connector block at the fuse access hole, have removed plastic trim, all clean and dry, will get round to checking and if needed cleaning the hidden fuse.

Hello,
Update on LO reading on digital dash, found Ambiant temp sensor connections to be clean and connections block a tight fit, decided to try and rule out either Ambiant temp sensor or engine temperature sensor, having already bleed the air from cooling system, I did this by heating up the Ambiant temp sensor with a hair dryer then LO disappeared off digital display and a temp reading appeared, it was all over the place but settled down and the temp reading slowly dropped, after a while LO reappeared, heated with hair drier again and a falling minus temp reading appeared a eventually a high positive falling reading and eventually LO again, easy way to test it,, so appears to be faulty Ambiant temp sensor, ordered new one.

Be aware if you bled the coolant system that you must open the bleeder on the cylinder head while the engine is idling to purge all the air out of the block.

I attach a clear hose to the bleed nipple and leave the other end hanging on the handle bars. That way, air can only escape and not make its way back into the block.

Without doing this crucial step, the cylinder head will overheat and you will never get a indication that your engine is going Chernobyl.

Thanks sbaert, thats exactly what I did.
