Smoke!!!

[bushido]

Battery on the bike was almost dead after a winter spent in the garage. I know it's not a great idea however I went to jump the bike from the car to take it a wee run hopefully giving the battery a charge.

When I plugged it in and went to switch it on the bike battery area immediately started to smoke (lots of it). I've since removed the battery, both battery and jump leads were very hot!

Anyway the question is, have a fried anything electrical in the bike?

That isn't smoke. It's steam. Steam from the steamed clams we're having.

Mmmm.

Steamed Clams!

Maybe the Amperage coming from the Car battery was too big for the bikes amperage

Most likely you managed to connect a short circuit. The bike would only pull the amps it needs.

What did you connect to where?

It sounds like you did same as my Dad when dementia was kicking in
Connected red to black and black to red.

Was the car running when you jumped it?

I've seen cars where the terminal colours are seemingly backwards, a friend didn't double check the symbols on his battery and wired his Corsa B incorretly to my clio because for some reason the - was red and vica versa.

In my experience though it's usually you've shorted out the leads on something inadvertently, cars are usually pretty good, but it's not unusual to find the tank or frame run near the bike battery terminals, big jump lead clips can easily lean on metal by accident and that would cause smoking.

Also, you can't push amps into a system, the system draws amps from the battery/source, so that wouldn't be an issue. You could provide too many volts, say by wiring up to a lorry, which would do some odd stuff (like potentially run the starter motor at double speed), but you won't have done that.

I doubt you've damaged anything anyway, I've had smoke a couple of times with no long term damage, as long as you stopped pretty sharp.

I was told a few days ago that you should never connect a fully charged high Ah battery to a flat low Ah battery as apparently, as you do, the two will try to equalise and a massive current flow will jump through the leads.

We get this a lot in the campervan world where people let their leisure batteries run flat, then start the vehicle and when the voltage sensitive relay between the batteries connects the two, it blows one of the strip fuses on the lead between the two batteries. These are 50A on my setup!

Thanks for the informative posts, new battery ordered.

Cheers

I always put positive to positive and donor battery negative to bike foot peg. Done that for years.
