Hi,i need to remove the battery on my 06 streetglide,i need to do some welding on rear fender ,fender needs to be in place as i am putting a 180 tyre and rim on bike so need to cut the fender down the middle and add a strip to the centre,what i need to know is by removing the battery will i mess up the alarm system or will it work fine again once i replace the battery,also is there anything i need to look out for or disconnect electrical wise while i do welding thanks
