dell Posted Sunday at 06:58 PM Posted Sunday at 06:58 PM Hi all, I started my bike up couple days ago, bikes always on optimiser, started no problem, I stopped for a coffee after 35 miles, tried to start the bike nothing, I was kindly given a start from a guys jump leads, bike was running rough but managed to get home, tried to start it again, again nothing, after being on the optimiser all night it started the next morning. Appreciate any help ,thanks in advance. Dell
docc Posted Sunday at 07:12 PM Posted Sunday at 07:12 PM Hi, Dell! What is the make/model/age of the battery? What relays are in it?
dell Posted Sunday at 07:40 PM Author Posted Sunday at 07:40 PM Hi docc, Its a 2002 v11 le mans, i unfortunately not good mechanically so I don't know what relays are on the bike. The battery is a motobat i can't remember the number, but when I looked it up it appears to be the correct one, I have only owened the bike for about 3 months so not sure of the battery age. Cheers Dell
audiomick Posted Sunday at 08:32 PM Posted Sunday at 08:32 PM Hi @dell. Looks like @docc is heading in the right direction, but so's you know where he's heading: The symptoms indicate that the battery is not delivering properly, i.e. dead. 'Nuff said, do what docc says. 2
dell Posted Sunday at 08:48 PM Author Posted Sunday at 08:48 PM My son had a volt meter i can borrow. Forgive my ignorance if the battery is dead would it not charge up, I left it on the optimiser over night and the following morning the bike started without any problems. Regards Dell 2 1

Without wanting to worry you too much, there is a whole chain of things that can lead to what you are describing. They are all cureable, and mostly *fairly* easy to find. You have to go through it systematically and methodically, and eliminate possible faults one after the other. Thereby, start with the most obvious and simple and leave the complicated stuff until the simple things have been eliminated or verified as the cause of the problem. Battery is easy, and on the top of the list because you don't know how old it is, or how it has been treated in the past. Batteries age. What can happen when they get old is that they can take a charge, even start the bike once, but have no capacity any more. At a second start attempt, or even the first, they can't deliver enough energy to turn over the starter motor, even though they look like they are charged. That is fairly easy to test. Get the multi-meter. Measure the voltage across the battery terminals. It should be nearly 13V. Leave the meter connected and press the starter. If the voltage drops below 10V, the battery is most likely too old. There are several other things, known issues with a V11, that can cause the starter motor to not turn over, but check the battery first. One thing at a time. PS: this optimiser, what is it? There are "float chargers" on the market that are actually not really good for the battery. Edited Sunday at 09:03 PM by audiomick 1 1
dell Posted Monday at 04:21 AM Author Posted Monday at 04:21 AM Hi audiomick, Thank you and docc for taking the time to respond, I will probably take it to the local bike shop for them to have a look for me as I said I am not mechanically minded Cheers Dell OptiMate 1 Duo 12V Lithium and Lead Acid Motorcycle Automatic Battery Charger Maintainer OptiMate 1 Duo 12V Lithium and Lead Acid Motorcycle Automatic Battery Charger Maintainer 200+ bought in past month 1 2
po18guy Posted Monday at 07:26 AM Posted Monday at 07:26 AM I would make certain that you have a good earth. That cable ends at the transmission housing. It can be reached with some dexterity. I would clean the cable end and the transmission surface, then use some Caig DeoxIt or similar to protect the connection. That, and the underseat relays are legendary for going on strike at the most inopportune moments. Good replacements are not that expensive and they are plug and play. Then, a check of running voltage. OH! The voltage rectifier is adjacent to the oil cooler. Trace the wires from it to the frame. There is a multi-pin connector that is susceptible to rain water and corrosion. I had a similar problem that went away when I cleaned that connector. 2 1
mikev Posted Monday at 12:51 PM Posted Monday at 12:51 PM I'm not a bike mechanic either but had no problem installing a new battery in my V11 when i got it, (still use the old one on the outboard motor). I also replaced all the relays with the recommended Omron relays discussed elsewhere on this site. Found good ones on Ebay. Bought extras. I applied Craig Deoxit to the terminals and dielectric grease to pins when installing the new relays. I keep extra relays and fuses in my tail bag just in case the bike decides to get funky somewhere inconvenient. 2
po18guy Posted Monday at 07:32 PM Posted Monday at 07:32 PM All good. The rectifier multi-pin connector and the transmission ground would be next in my book. Followed by a check of running voltage 1
dell Posted 1 hour ago Author Posted 1 hour ago Found out the problem, rectifier was fried, its a ducati one, energia 343637, as these are expensive has anyone used a cheaper one that works well cheers Dell 2
dell Posted 1 hour ago Author Posted 1 hour ago Thanks, Not quite yet, I need to buy a new rectifier, need to know has anyone used a differnt one from the ducati one. Cheers Dell
