XmisterIS Posted June 3, 2011 Posted June 3, 2011 I had an "adventure" yesterday - back tyre got a flat on on the motorway. Completely shredded. I'm not really that bothered because it was knackered anyway and due for an MOT and tyre change a week Monday anyway! So I'll be bikeless for a week, never mind.Anyway, where I'd left it with the hazards on for so long waiting for the AA to arrive (two hours ), the battery is now pretty much flat. I know that it can ruin a battery if it gets to the point where there is no juice at all in it, but this one still has enough juice to power the dashboard and produce a feeble glow from the headlamp. Will it be good as new if I jump-start it off the car?I then plan to put tyreweld into the rear tyre and ride it (carefully!) to the bike workshop which is about 2 miles down the road. Unfortunately, they don't have facilities to come and collect bikes and to get it transported there would be an extra cost.That being said, tyreweld is about £6 from Halfords and being so close it may cost a tenner to get the bike transported a couple of miles only, in which case I'll do that and save myself the hassle for the sake of a few pounds.My main question in this rambling post, however, is will the battery still be a good'un when I get it charged up?

Guest akey Posted June 3, 2011 Posted June 3, 2011 Yea it should be fine mate, if you can get hold of an Optimate or similar then they have a deep discharge recovery mode as well.I had similar with mine - left the spotlights on overnight put in on the optimate for 24 hours and it has been fine ever since Quote
XmisterIS Posted June 3, 2011 Author Posted June 3, 2011 I haven't got an optimate, but I do have a diesel car ... will that be fine to jump-start it with? Or will it blow it to buggery? (2 litre diesel). Quote
Decor58 Posted June 3, 2011 Posted June 3, 2011 I left my heated grips on for several days and it completely and utterly drained the battery. I hucked it up to a mates car and went for a ride for a couple of hours and it's fine now.Just dont stall it within the first 20 mins or so otherwise you'll have to jump it again!As for getting the bike to the garage, it's only 2 miles, push it!!!Hope you get it all sorted mate Quote

Decor58 Posted June 3, 2011 Posted June 3, 2011 Nope, last time I had a flat I took the wheel/tyre off and carried that 3 miles which would be a lot easier now I think about it. Quote
XmisterIS Posted June 3, 2011 Author Posted June 3, 2011 Oh dear ...I tried to get some juice back into the battery, no dice, all that happened was I've completely drained the battery now trying to start it, so I think the battery's a dead'un. Also the rip in the tyre is too big to tyre weld.I gave up and phoned the local Suzuki people who are going to come and collect it for free on Monday and get the thing MOTed, new tyres, battery, etc. Might cost a little more that way, but it's the simplest solution!

Decor58 Posted June 3, 2011 Posted June 3, 2011 Fair enough, at least you know it will all get sorted that way. Quote
Colin the Bear Posted June 3, 2011 Posted June 3, 2011 Some bikes don't like being jumped off a car or another bike. Power output / Damage to electronics and all that. I use one of thesehttp://www.maplin.co.uk/portable-jump-s ... ssor-49038Easiest way to sort a puncture is take the wheel off. Cadge a lift or take it on the bus to the tyre shop. Who wouldn't stop for someone thumbing with a wheel Quote

Who wouldn't stop for someone thumbing with a wheel I know that now! Lol! The chap in the garage that I was going to take it too said, "Oh, just jump it off a car, won't be a problem", so I tried ... no dice ... so I phoned up the Suzuki dealer and he said, "you did what???!!!" and "I can't believe the idiot told you to do that!" I hope I haven't knackered the ECU. Mind you, when a so-called "professional" tells you it's ok to do something, you tend to trust them! Luckily I can afford a new ECU, should one be required, but as with all these things, I'd rather spend the money on something else! Note to self - always phone Suzuki in future ... Quote
Decor58 Posted June 4, 2011 Posted June 4, 2011 It depends on the size of the car. Old bikes you can jump them off most cars as long as they don't have a massive battery. Newer bikes any small car really, never had a problem with either though.If you're worried about frying circuits just don't rev the car engine while it's connected. Quote
XmisterIS Posted June 4, 2011 Author Posted June 4, 2011 I can assure you, there was no revving involved. The rev didn't happen. The accelerator pedal was out of bounds ...My car is a huge one, however, 2 litre turbo diesel, which is why I'm slightly worried! The battery is the size of a breeze block ...I hope that all I've done is drained the bike battery right down to nothing. Anyway, I'll find out on Monday! Quote
Decor58 Posted June 4, 2011 Posted June 4, 2011 I jumped my mum's cbr600 off a vw gold diesel 2L before and had no problems. Quote
XmisterIS Posted June 8, 2011 Author Posted June 8, 2011 Turns out battery was fine, recharged fine, new tyres fitted, back on the road!! Quote
Tango Posted June 8, 2011 Posted June 8, 2011 Hey...that's good news.You shouldn't have a problem jumping the bike from a car. The alternators turn out the same sort of voltage irrespective of the size of the battery. Only the current would vary. The only time it could cause a problem is if you had a fault in the electrics on the bike and the current available from the car (via an un-fused jumper lead) could burn wiring or components out!We jumped Mandy's Bonneville T100 from her Octavia with no probs some time back with no ill effects.Anyway...you're sorted now... this is just for future reference.Bob Quote
