PostSubject: Battery Drain... after 2 weeks sitting each time...   Battery Drain... after 2 weeks sitting each time... Icon_minitime1Thu Sep 24, 2020 5:00 pm

Hello all,

I'm in love with my GRiSO, and am almost done shaking out all the bugs and modifying it to suit my liking.... delicious.

Question I have for you all, I seem to have a consistent battery drain. I understand that the security on the bike often drains the battery, but after 10-14 days of sitting on multiple occasions it is just flat. I fully recharge the battery, make sure any accessories have their own battery disconnect so to ensure it is not draining the battery... what else can I do?

Is there a way to disable the security on the bike? So that it doesn't drain the battery? Is there a better battery to get which won't drain nearly as fast?

Any other suggestions? Its a 2013 GRiSO with 5k miles on it...

Thanks
Richard

Just pull the main 30A fuse under the seat. You'll have to reset the clock when you re-insert it and fire the bike up. If it's still flattening the battery in two weeks the battery is dying.

The flashers also draw a little current, I think its something like 40 microamps per lamp, 160 in total.

There's probably some other inputs drawing current as well.
I can leave mine for several months and it will still start so perhaps its time you had a new battery.

Buy an Oxford Solariser or similar. I've never had a problem since using it, even in a British winter.

Here's an Amazon linky. I'm sure you can get these in the States.

You need a battery tender or equivalent.
My favorite is the Optimate 6, it can desulphate in injured battery and bring it back to life (sometimes LOL)
I have 12 bikes, 3 rarely driven old Porsches, and a tender on the bow of the big boat, so I have one for each plus a couple extras.

The security alarm should not be draining the battery at all, something else is causing the drain, or the battery is failing.

Hey all,

Happened again. Its a new battery, and frankly the second new battery I put in it recently...
I hooked up my iphone charger to an off switch so to completely disonnect it from the battery when not in use, so I think i ruled that out.

There is a small wire on the battery that has a blue tip, not sure if this is stock of the previous owner hooked up something I don't know about...

Do stock 2013 GRiSO's have a small wire running to the battery?

Thanks,
Richard

Nope, definitely not. Disconnect it and find out where it goes to.

Could be a StartusInteruptus wire for bypass.

I'm more concerned about the lack of a proper terminal on the earth strap and what those other two small wires are. It hasn't got a bloody Power Commander on it has it?

You're not parking it with the key in the ignition (but switched off)?

That makes no difference. Battery drain is the same with key in or out.

Hmmm. I've had issues where the antenna kept the ECU alive because the key was still in the ignition.

But it's been a long time since I've left keys in the ignition, so it may have been a one-off (or a fading memory!).

The antenna is connected to the dash. The ECU goes to sleep until "key-on".

The drain is all dash. Constant 1.9mA with key in or out.
Jumps to 10.48mA momentary every 3 seconds when the "Anti-Theft" light blinks.

If there is an unswitched usb socket disconnect it. They draw power and some draw quite a lot. TO quote stack exchange website "Nearly all AC to DC converters, by design, draw a very small idle current when you aren't charging any devices. "

The negative battery terminals seem to be very weak, mine fell apart.
It wouldn't be easy to find a standard lug to replace it and tuck in there so I just bent one from brass sheet and sweated it on using rosin score solder. Copper sheet would be ok if you can't find brass.
Make sure you scrape the battery posts and apply a little grease to prevent Lead Oxide forming.
