[GSXR_BIKER]

Hi All, bit of advise needed, fitted new battery to bike I am doing up, turned over fine (Didnt start, fuel not connected) for some reason, next day Battery was flat (Was fully charged) Re-charged battery, but now when I push the starter, nothing happens, I presume ther is a fault with the ignition, which is perhaps sorting, and now burned out?? Any suggestions?? Ta

mmmmm sounds familiar. My flatmate had trouble with his battery....kept losing charge so he replaced it.....next day the new one was flat. Charged it up and oh helloooooo starter motor burned out. Replaced that and hasn't looked back since.
It could well have just been the starter from the begining being rooted and drawing too much but I dunno. Electric's as far as im concerned are best left to geeks...

Hope yours isn't the same...cost him an arm and a leg to get a new starter. Damn honda cbr's

Golden rule with electrical stuff.. Don't let the smoke get out, every thing works fine until the smoke gets out, as soon as that happens it stops working. Coincidence.. I don't think so!

Without knowing the state of your "do up", I can only suggest a simple isolation test.
Re charge the battery. Remove all fuses except the ign and main fuses. (isolating the lighting circuits).
If the battery discharges again, you can expect the fault to involve the ign sw/ starter/charging sys.
If it is staying charged, the fault is probably related to the lighting circuit.
Track down those stray electrons brudda.
Good luck.
You can narrow it down further by removing ign fuse, or seperate relay fuse if it has one.

You could try testing the amperage being drawn at key out rest by connecting your multimeter between the positive lead and the positive terminal on the battery and setting the multimeter to A. Don't try starting the bike like that, it'll draw so much current it'll eat the multimeter. It should, in theory, be drawing nothing then the key is off.

Sounds like you are going to have to go through a process of elimination and check one thing at a time. Start with the batter first.

Do a check to make sure that the battery is ok and fully charged. Check the voltage across the battery with the multimeter. Should be 12v.

Agree with previous comments. Use the multimeter to check how much charge is being put out by your bike it should be about 14.5v when the bike is running. If it isn't doing this then the charging circuit is not working.

Then start looking at stuff that needs to be replaced.

Good luck
