Guest duc888 Posted April 1, 2012 Share Posted April 1, 2012 Good Day, Got a really wierd problem with my 85 VF1000r...started it yesterday, no problem, went to start it today, minor fuel pump noise then a click as if the battery was flat, and the dash lights went out. I don't think I left the ignition on, anyway tried to charge the battery, to no avail. I can only get lights if the charger is in supply mode. Off the charger the lights will come on in park, brakelight and indicators work. When I switch on the main lights there is a very faint glow from the element and the tail lights are very dim. It would appear to be a completely nackered battery as it does nort seem to take a charge and the charger comes up with an error light. Can a battery go from working to completely useless overnight or do I have a worse problem than that? Thanks in advance. Link to comment Share on other sites More sharing options...
Guest Posted April 1, 2012 Share Posted April 1, 2012 Unusual, but possible--- You've checked all connections and grounds? Link to comment Share on other sites More sharing options...
Guest Posted April 1, 2012 Share Posted April 1, 2012 Also, maybe the igntion switch? Link to comment Share on other sites More sharing options...
Guest Posted April 1, 2012 Share Posted April 1, 2012 short circuit on main voltage probably happened to me, starter switch positive terminal grounded itself to the frame, flat battery within hours, such state usually damaged acid batteries, I was lucky having an odyssey drycell battery which came back to itself after some time...

Guest Posted April 1, 2012 Share Posted April 1, 2012 Thanks, for the info. Being a bit thick when it comes to vehicle electrics, how do I go about testing this without checking all the wiring and connections? I'll start stripping it down over the long weekend.

Guest Posted April 1, 2012 Share Posted April 1, 2012 look for melted wires and connectors first Link to comment Share on other sites More sharing options...
Member Contributer DaveB Posted April 1, 2012 Member Contributer Share Posted April 1, 2012 Batteries can suddenly fail, its happened to me a couple of times when I've been to the mall and the battery is dead when I try to come home. Stuff can drop off the plates and cause an internal short to one of the cells. Link to comment Share on other sites More sharing options...
Member Contributer YoshiHNS Posted April 1, 2012 Member Contributer Share Posted April 1, 2012 Did you take a multimeter and see what kind of voltage you are getting with the charger on it and off? What amps are you charging it at? Link to comment Share on other sites More sharing options...
Guest Posted April 1, 2012 Share Posted April 1, 2012 Thanks for the pointers. I've just taken the seat off. No melted wires and nothing smells funny. The main positive from the solenoid seems a bit soft/pliable at the ends, I would have thought this should be quite stiff, given the thickness. The fuse on the solenoid is intact. The battery seems to be storing some power, I can occasionally get the dash lights on (seems to have a delay or something reseting). After it trips? Sometimes, if I switch off the ignition unplug the connector by the solenoid and replug the connector, I can get the dash lights back, however as soon as I put load i.e main lights (low load from parking lights or indicators is ok) or hit the button there is a soft click from either the solenoid or something very near to it and the dash lights go off. I'll do some more in depth fiddling tomorrow and try and get another battery. Yoshi 11.4 V across the battery with charger off and ignition off. 13-13.5 V with charger on. 14.5 V with charger on and ignition on. 0.2 V across the battery with ignition on and dash lights off.

Member Contributer YoshiHNS Posted April 1, 2012 Member Contributer Share Posted April 1, 2012 Battery is most likely dead. If the voltage drops that much as soon as you try to draw power. You could leave it on the charger at a low amp setting and see if it crawls its way back up to 12.5-13V, but I don't think it's going to work.

Guest Posted April 1, 2012 Share Posted April 1, 2012 Thanks, I'll try and borrow a battery from a mates bike shop before splashing out on an odyssey as per wlodek's suggestion. I have these in my 888 and BM and they have given no problems. Cheers Link to comment Share on other sites More sharing options...
Veefer800Canuck Posted April 2, 2012 Share Posted April 2, 2012 You probably have an internal short inside the battery. When that happens, they go bad instantly. Link to comment Share on other sites More sharing options...
Guest Posted April 2, 2012 Share Posted April 2, 2012 Thanks for all the pointers. Borrowed a battery from a mate, started no problem. I must say I was really surprised a battery could fail that quickly. Thanks again Link to comment Share on other sites More sharing options...
Veefer800Canuck Posted April 2, 2012 Share Posted April 2, 2012 I was riding down the road one day, had been riding for hours with no problem. Stopped for gas, bike would not restart. Dead short between two cells in the battery. Boom! Done! Link to comment Share on other sites More sharing options...

Guest Posted May 3, 2012 Share Posted May 3, 2012 You must have really bad "gas" in the colonies Thanks again to everyone for the help. Link to comment Share on other sites More sharing options...
