Call me a stupid ass, a couple of days ago I thought I wouls start the bike up as it had been standing unused for a while. connecting the jump leads from the car I saw on the bike battery a cable with a red sleave on it, and autmatically assumed it was positive.
A few seconds later smoke was emanating from the battery compartment. Unplugged it as quick as I could, but the bike is now completely dead, nothing even shows up in the LCD display.
Have I just landed myself a large repair bill? I should think at least the battery is knackered, what about the ignition.

Thanks
Robert

DEE DEE DEE!!!!!

Robert, you may have been right about the red sleeved cable being the + side of the battery, and your issue may be elsewhere.

Questions:
What year is your LT?
How old is the battery?
Have you checked the fuse boxes (3 of them under the rider seat, just ahead of the passenger seat.

At the very least you will have to replace the battery, and that should be your first step. Then we'll take it from there.

Did you in fact connect the jumper cable incorrectly, or are you not sure? Sounds to me like you just might have a very dead battery. But you still should be able to connect the jumpers (properly) and see if the LT starts/runs.

Robert,

Living next to Canada, I went thru three batteries in four years of LT ownership.

How long is a while?

Is your battery gell or not?

Did you remove the battery and clean the terminals yet?

Check your battery now at any AutoZone for cell integrity before you get too wound up. Last time I talked to Memphis brass, they sold over 58,000 motorcycle batteries. Call the storre before you go there. Way cheaper than OE.

You may have pulled a ground by accident. Big car cables can be a pain, especially if they are cold and stiff.

Thankfully your ignition may have been shut off which would eliminate cross currents and hopefully your sensitive electrical systems on the bike.

It still works

thanks for all the replies. plucked up the courage this afternoon to have another go at starting it. thankfully it started right away, ran a bit rough tho. the LCD display is back on as well.
Ran it for 15 mins, tried to re start it but batteryis still dead. Suppose i will have to wait until tthe spring and I start riding it again to see if I have completely buggered it up.
Having lived in Naples, southern italy for the previous four years before moving here, (now live in Spokane,Washington. Yawn.) having to lay up a bike for so long in the winter is a real bummer. I`m used to riding all year round.

Thanks
Robert

EXCELLENT news! :)

That battery is going to need an all-night charge on a 2A charger if it has any hope of being revitalized at all.

Well, good news: having jump started thousands of dead batteries during my 17 years on patrol, I've NEVER come across one where the red sleeve/markings were not the positive terminal.

Put a trickle charger (2 amp or less) to maintain the battery for winter and you'll be fine.

It depends on the type of battery. I used to always prefer a 2 amp trickle charge until I accidentally drained my Odyssey. I checked their web site and was surprised to find that they recommended a 2 hour 10 amp or 1 hour 20 amp charge. It seams that the “These chargers, such as the 1.25 amp Battery Tender® from Deltran are not capable of charging a deeply discharged ODYSSEY® battery.”

That is exactly why the alternator fried on my '75 MGB when my father in law put the new battery in it. Ther battery is behind the passenger seat and has a long BLACK cable for the positive lead to the starter and a short RED negative lead to the frame. Granted not factory installed but always best to check the destination of the cable when in doubt.

Yes John, you're so right! I have never come across an MG. That could have been UGLY!!

IIRC at the time the Britts connected the positive to the ground instead of the negative. I guess that threw a curve to a lot of people. Maybe Woolly can confirm...

You are correct Gilles. It was back in the 6 volt days and I think a few early 12V were positive ground as well. That contributed to the blowing of the alternator diodes. I have had several old british cars but none were that old.
