So I just picked up my first BMW (1985 K100RT)
When I was looking at it before I bought it there seemed to be a charging issue
I thought it was due to the fact that the owner had bought the battery at a tractor supply store
It's actually a law mower battery
The way it plays out is whenever I tried to start the bike, hell, when I turned on the ignition system, ALL power died
Even the clock would reset to all zeros
If I hooked it up to another battery or a battery charger the bike would start right up
VROOM!
Sweet
It would go right down the road
Love at first ride
Until I shut off that is
Then it was dead dead dead
Even after trickle charging all night
So I figured there was some sort of loose wire in there somewhere
As I said I'm we to these bikes and have never had a bike with a full front fairing
Anyone see what's coming?
So I tore off the front fairing
Ug
My 1970 CB 750 had most of it's wire connections inside the headlight bucket
Which is why I tore the fairing off
After I got it off I wasn't surprised to see no wire connection
So I pulled the tank
Clever putting it down there
Fiddle with this one
Pull that relay
Hooked up the charger again
Starts right up
Take it off
All dead
But I heard a small pop coming from further back
Come to find out THE POSITIVE BATTERY TERMINAL WAS LOOSE
That was all
Took me 6 hours to find out that the terminal was loose and a bit corroded
(hand slaps to face)
Guess I needed to get to know how things are laid out
Glad I didn't break anything

a win is a win farm ....enjoy !!

did you do that hundred times? ........
Oh, have your heard about KISS (Keep It Simple Stupid)?
Most of us have been there before.
Enjoy your new ride
