Bridging positive and negative battery connections?

[Millsie]

Battery is completely dead in motorbike, is it possible to temporarily bridge the positive and negative connections to simply use the bikes alernator to power the lights instead of the battery sucking up all the juice?

Edit: the reason im considering this is because im suck in foxton and want to continue through to my destination..

That's going to blow the fuse.
Just disconnect the negative from the battery.

not like I think you are thinkin

SOME bikes there are ways , What you might be looking at is to take the output wire after the regulator rectifier into the ignition circuit ie as you say

Depends on the bike though

Depends on how the circuit is wired ,,,its wont cause a prob to try though

Should run with a dead battery, will require some volts from somewhere to fire it up though.

A short across the pos and neg is a dead short on the alternator, which means no volts to anywhere to power the bike.

Dead battery can try to suck the alternators goodies away giving poor spark and weak lighting.
Remove negative allows no attempt to charge battery and the alternator body becomes the negative so all power from regulator rectrifier goes to ignition and lights. Bike will need jump started or push started.

We need to know the bike

it might be a bsa with a generator hahaha

Have you checked the tension on the power band?

As mossy says, remove negative, maybe put a capacitor in there if its CDI to help smooth out the voltage.

Only if there is a fuse between alternator and battery, often there is not. In which case good bye reg/rect.

DO NOT BRIDGE THE BATTERY TERMINALS, this will destroy the charging system on the bike. best option get a battery from somewhere repco sell bike batteries if the local bike shop can't help, even if it is a smaller battery it will be fine just pack out the battery box so it can't slide round. If you fit a smaller capacity battery it may not have a enough grunt to start the bike you might have to jump start or crash start it.

Doesn't the RS have a kick start?

Why not just use that?

Also, if the battery is completely dead, it might be the charging system is the problem...

Hahahà that's what I'm thinking
It may be a BSA ..?
You can remove terminals , on some bikes but not all
My gornio scooter runs fine with no battery , but my St1100 don't

Running without a battery risks blowing important stuff up as the charging system may overload components. The battery absorbs the charge. Here's a quote from Shorai tech on the subject.

" It does NOT disconnect the battery from circuit on overcharge, as that will lead to blown Regulators and/or ECU...".

Also, a completely dead battery won't carry enough charge to run the bike even if jump starting it or kickstarting it.

Take spanner spinner's advice.
