When starting my bike this morning the battery sounded a little flat cos the starter motor was only just turning over, but yesterday day i did allot of short journeys so no real worries and I was going for quite a long trip today so it should charge its self.
when id filled up @ the petrol station I ended up Bump starting it cos the batt was even flatter NO FUN .....Then about 4miles down the road my indicators and lights where barely working, anyway I went back home and the batt is totally flat the voltage was reading 4.5 V when running so I charged it and popped it on the bike, started her up and the volts where dropping like fly's even while revving the bike. Then I popped my dads NEW battery on and it was reading above 12V while it was running then after a few min is started dropping to 11.99 then 11.80 .......11.70 and so on so I stopped the engine and watched the battery recover back to 12/13V.

But now I don't know what to do!!! I think my battery might need replacing anyway cos after putting my dads new one on it seems a bit crap, but the main thing is that the new battery was losing power while the engine was running rather than charging.

anybody got any Hints where to start cos I HATE electrics
(iv checked all the fuses BTW )

Thanks peeps

Maybe an altenator connection has come loose?
but don't ask me where to look for that one!

well, if you have AA membership, they will try and fix it for you

my bike did that. alternator was blown.

seeing as its a suzuki the alternator is built into the left hand casing as you look at the engine. drain the oil, get it out and look at the windings. if they look burnt out, its becuase they are. you might also get the "dead electrics" smell.

if its gone i'll be ablew to get you the address of the people who rewind them, seeing as i got mine back this morning.

have fun.

Out of interest Robby, how did the rewinding go? Was it expensive and does it now work?

Hi

Dodgy wiring from the alternator to the regulator / rectifier and then onto the battery, dodgy regulator / rectifier or dodgy alternator.

The wiring should be possible to check with a multimeter, and with the alternator you just really need to check for continuity over the relevant wires. The regulator / rectifier may be tested, but you would have to read the manual for that

All the best

I'v checked the continuity over the 3 yellow wires from the reglator fine no Beeping on the multimeter. also it reads a steady 12.5Volts at idle speep contuning up to 40+ volts when u rev it.
So its looking like a problem with the regulator / rectifier and i aint got much of a clue how 2 test that.

& does anyone have any ideas about the price of a new regulator / rectifier ???

Thanks for all your help

about 60 quid, could be a bit less cos yours will just be the DR350 one.

Hi

Voltage going up like that is pretty much a sure sign the regulator is fried. May well have taken your battery with it

All the best
