Mickly Posted February 13, 2023 Share Posted February 13, 2023 After fitting the heated gloves last week, I’ve eventually got round to trying them on the road, only to get a click when trying to start the bike, now before I go down a rabbit hole of duff battery & dodgy connections, I tried to start it with the Optimate attached, should this have given it enough ooomph to start or not coz it’s only a trickle charge?

Fiddlesticks Posted February 13, 2023 Share Posted February 13, 2023 I wouldn't have thought so. Mine has had an Optimate attached for the winter. I'd leave it on for a few hours and check to see if all the lights are green to indicate a full charge. Then disconnect it and try to start the bike. 1 Quote Link to comment Share on other sites More sharing options...

Ta, Funny enough the light went green minutes after fitting it, but still just a click, I’ve disconnected everything except the charger & I’ll have a go in the morning.

Stu Posted February 13, 2023 Share Posted February 13, 2023 No where near enough from the optimate they only put out 0.8 amps you would need around 200 amps to start it If it's gone green within 30 minutes then I suspect something is wrong as a flat battery would take a few hours to go green on an optimate 1 Quote Link to comment Share on other sites More sharing options...
Mickly Posted February 13, 2023 Author Share Posted February 13, 2023 I’ll try jumping it off the campers leisure battery tomorrow without the battery connected & see if that does it. 1 Quote Link to comment Share on other sites More sharing options...
Mississippi Bullfrog Posted February 13, 2023 Share Posted February 13, 2023 Sometimes a bad battery can fool a charger. They show the indicator that they are charged but the battery fails as soon as any load is applied. If you put a 12v bulb across the battery see how the voltage shows then. I had one do just the same as you describe but with just single bulb you could see the voltage dropping. 1 Quote Link to comment Share on other sites More sharing options...
Fleck Posted February 13, 2023 Share Posted February 13, 2023 Make sure the battery clamps are tight 1 Quote Link to comment Share on other sites More sharing options...
Mickly Posted February 14, 2023 Author Share Posted February 14, 2023 Tried the camper battery & all it would do is cough once then stop every time I hit the start button, it also did the same using the battery on the Disco Quote Link to comment Share on other sites More sharing options...
Mickly Posted February 14, 2023 Author Share Posted February 14, 2023 Used the campers vehicle battery & started its engine, the bike has now started - so I think the battery is the culprit, it is 7 years old !! Quote Link to comment Share on other sites More sharing options...
Stu Posted February 14, 2023 Share Posted February 14, 2023 Another good check is to stick a multimeter on the battery and hit the starter and see what the voltage drops to 1 Quote Link to comment Share on other sites More sharing options...
Mickly Posted February 15, 2023 Author Share Posted February 15, 2023 It’s gotta be the battery. This morning I did as suggested by @Stu i.e. Attached a multimeter to the battery, at first it read 12•85V, I switched the ignition on which lights up the dash, driving lights & primes the fuel system… it dropped to 11•35V, then I hit the start button and it span over once and stopped ( Instead of just whirring ) & it dropped to 8•65V. On reflection the heated gloves probably did for a dying battery. Thinking about why the car batteries wouldn’t start it without the engine running, I reckon when it was 1st tried and failed it probably stopped at the point where it needed the most power so needed more grunt to overcome that. Fingers crossed that the Sprag clutch hasn’t been damaged. Picking up a new battery tomorrow Quote Link to comment Share on other sites More sharing options...
Stu Posted February 15, 2023 Share Posted February 15, 2023 Definitely sounds like a duff battery to me 1 Quote Link to comment Share on other sites More sharing options...
Mickly Posted February 18, 2023 Author Share Posted February 18, 2023 (edited) New battery fitted, all is good Good job as it’s going to Suttons in Tamworth to have a service item completed that should have been done 2 years ago, a part wasn’t included in the service kit from Triumph so they said they’d get in touch when it arrived & we all forgot They’re having a refit and found the part in their stores area with my details on it, gave me a call & asked me why As it’s the hub nut for the single sided swinging arm they obviously didn’t grease the hub as the nut has to be replaced when it’s done. FairPlay to Suttons, got it booked in foc with no argument. Edited February 18, 2023 by Mickly 3 Quote Link to comment Share on other sites More sharing options...
