I have a 2001 Sportster

When I bought the bike, I believe it had the original battery in it, that was 2009. The battery lasted until 2012, since then, I have had to replace the battery every year, usually about half way through the year.

So in 2012, I relocated the front turn signals myself, and since then my battery dies every year. Guessing this means I have a short, caused by the installation. Also, when I rev the bike high, the right turn signal, front and back turn signal brighten...

Not savvy with electrical, please help and tell e what it all means and how to fix it.

Thanks
